The PVSC-40 takes place June 8-13, 2014, at the Colorado Convention Center in mile-high Denver, Colorado. Denver is a beautiful city with sunny days for most of the year, and one of strong solar importance, with many PV companies and the National Renewable Energy Laboratory located nearby. We are in the midst of a crucial time for energy management on our planet. Environmental, climate change, and energy security concerns are among the most pressing issues we face today. Clearly, photovoltaics can be part of the solution. Public awareness is growing that photovoltaics can shape energy use patterns for future generations - much as the automobile transformed transportation within a time span of 50 years - as evidenced by the exponential rise in photovoltaic production over the last decade. Science and technology developments in PV over the next several years, and their influence on the economics of PV installations, are likely to establish which energy technologies become dominant for decades to come. The purpose of our conference and our efforts to bring the world’s brightest PV minds together is essentially an educational mission. Our conference is here to exchange information on the fundamental principles, materials science, fabrication, characterization, and application of solar cells. In this modest way, we strive to create a forum which encourages discovery, advances understanding of all aspects of photovoltaics, and hastens the widespread availability of solar electricity and its multiple environmental, economic, and political benefits for humankind. The chance to share and discuss these crucial PV technologies, and what they mean for accelerating PV deployment, is what the PVSC is all about. Thank you for joining us in continuing the PVSC’s tradition as the preeminent conference dedicated to the science and technology of photovoltaics! The Technical Program is divided into 12 areas covering the range of important developments in PV, from fundamentals, materials science, devices, systems and reliability, through policy and PV deployment acceleration. In the PVSC’s oral and poster presentations, you’ll be able to hear the latest advances and breakthroughs in our field of photovoltaics. Our Technical Program Committee members come from all over the globe, and we are excited about making the PVSC an ever more international conference, with major contributions from all the continents of the world. The Tutorials and Short Courses program, taught by renowned experts in PV, is a great way to learn about a fascinating area of PV that may be new to you, or strengthen your foundation in a PV area you’ve been in for many years. The PVSC-40 hosts a dynamic Exhibition for companies and research labs to showcase their latest PV characterization, research, and manufacturing advances, bringing scientists and technologists together with leading PV industries and organizations. We are resuming our popular Solar Day in 2014, with many organizations showing how they are making solar electricity a reality in Colorado, and providing a model of PV acceleration for other communities. 40th IEEE PHOTOVOLTAIC SPECIALISTS CONFERENCE We will have some fun too. We’ll have Evening Poster Sessions for the first time at the conference on Tuesday night, with a reception-style dinner so you can feed mind and body at the same time. The Social Program has organized trips to see some of the best that Denver and nearby areas of Colorado have to offer for both attendees and companions, including touring Red Rocks, the chance to paint your own canvas, and hikes in the Rocky Mountains of Colorado. The Conference Dinner will be held in the breathtaking architectural space of the Hamilton Building of the Denver Art Museum. This event promises to be an evening of good art, music, food, and friends. I hope to see you there! On behalf of the Organizing, Cherry, and International Committees, welcome to Denver and the 40th IEEE PVSC! Richard R.

MORTON B. PRINCE RECOGNITION OF DR. MORTON B. PRINCE (Bell Labs Pioneer and PV Leader) The confluence of the 40th IEEE PVSC and the 60th Anniversary of the Bell Telephone Laboratories discovery of the modern solar cell provides us with a unique opportunity to recognize one of our most distinguished members of the world PV community. As a MIT graduate student, Dr. Morton Prince was recruited by William Shockley to join Bell Labs and their development of the relatively new “transistor”. While Mort was involved with the investigation of minority-carrier properties in these devices, he was approached by fellow group member, Gerald Pearson, about some incredible progress he was leading with this other new Bell device opportunity — the solar cell. In the late fall of 1953, Mort joined Pearson with responsibilities for characterization and device applications — and a seminal publication about the performance potential of the Si solar cell. History and Mort’s contributions to photovoltaics thereafter speak for themselves! He left Bell Labs in 1956 to become Director of R&D at Hoffman Electronics (Semiconductor Division), leading the efforts to establish PV as the “power of choice” for space applications with the first solar power satellite, Vanguard, in 1958. Mort Prince has had an incredible career in semiconductor electronics — and led the growth of PV as the ERDA and DOE manager for this technology from 1975 to 1993. In 1994, he was recognized with the European Becquerel Prize for Outstanding Merits in Photovoltaics. The world PV community owes a lot to Mort. This year, the IEEE PVSC is especially proud to have this special recognition of Dr. Morton B. Prince for his leadership and his pioneering and outstanding contributions to our PV technology. 40th IEEE PHOTOVOLTAIC SPECIALISTS CONFERENCE WILLIAM R. CHERRY AWARD This award is named in honor of William R. Cherry, a founder of the photovoltaic community. In the 1950’s, he was instrumental in establishing solar cells as the ideal power source for space satellites and for recognizing, advocating, and nurturing the use of photovoltaic systems for terrestrial applications. The William R. Cherry award was instituted in 1980, shortly after his death. The purpose of the award is to recognize an individual engineer or scientist who devoted a part of his/ her professional life to the advancement of the science and technology of photovoltaic energy conversion. The nominee must have made significant contributions to the science and/ or technology of PV energy conversion, with dissemination by substantial publications and presentations. Professional society activities, promotional and/or organizational efforts, and achievements are not considerations in the election for the award. This award is presented at each IEEE Photovoltaic Specialists Conference. The recipient is selected by the William R. Cherry Committee, which is composed of past PVSC conference chairpersons and past recipients of the award. Those nominated for the award do not participate in the process. To be eligible for the award, the nominee must currently be active in the science and technology of PV conversion. He/ she must have been active in the field for an extended period with the expectation of continued activity.

Sinton is founder and president of Sinton Instruments, based in Boulder, Colorado. Ron received his PhD in Applied Physics from Stanford University in 1987, following a B.S. in Engineering Physics from the University of Colorado in 1981. His studies at Stanford University included the demonstration of 28%-efficient silicon concentrator solar cells, the physics of highinjection solar cells, detailed device modeling, measurements of Auger recombination, and the test and measurement of concentrator solar cells. As a Research Associate at Stanford, Ron developed simplified versions of the sophisticated point-contact solar cell designs that could maintain the high efficiency while minimizing the process complexity. He continued this work during the early years of SunPower Corporation, focusing on solar cell designs and manufacturing processes potentially suitable for commercialization. Dr. Sinton founded Sinton Consulting in 1992. The company soon focused on the development of novel test and measurement instruments. This work resulted in many fruitful, and very international, collaborations and research papers. Innovations from Sinton Instruments that have become standard within the R&D community and the silicon manufacturing industry include the QSSPC lifetime technique, Suns-Voc measurements, and novel methodologies for measuring the efficiency of high-efficiency solar cells and modules. Dr. Sinton has maintained his special interest in the device physics of silicon solar cells. Running a metrology company has proven to be an effective way to be at the center of both of the R&D and manufacturing communities, offering opportunities to contribute at the most technical academic level as well as providing instrumentation to support tens of GWs of silicon solar cell and module production. Ron received the R&D 500 award in 2005 for developing instruments for measuring bulk lifetime in silicon ingots and bricks. He is well published and has coauthored 4 book chapters. He is an associate editor of the IEEE Journal of Photovoltaics and has frequently presented tutorials on silicon solar cells and device physics at the IEEE PVSC conferences, first in 1988 and as recently as 2013. Ron is a frequent contributor to conference program committees; especially the IEEE PVSC, the NREL Silicon Workshop, and the SiliconPV conference. Congratulations, Dr. Sinton!

OLIVER SCHULTZ-WITTMANN On behalf of the organizing and program committees of the 40th IEEE PVSC, I am delighted to announce the recipient of this year’s award—Dr. Oliver SchultzWittmann. He is recognized for his outstanding achievements in the development of silicon solar cells, including the current world-record multicrystalline cell (20.4%) and high-efficiency, low-cost crystalline cells developed for commercialization by a recently-acquired start-up company. Dr. Oliver Schultz-Wittmann started his work in the PV field in 1998 helping with rooftop installations while studying Physics at the University of Hamburg, Germany, where he received his diploma in Physics in 2001. His graduate thesis topic was the manufacturing and characterization of selective emitter structures on crystalline silicon solar cells in cooperation with the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany. In 2002, he began his doctoral thesis on high-efficiency multicrystalline silicon solar cells at Fraunhofer ISE. The highlight of his work was demonstrating cells made from this material with conversion efficiencies greater than 20%, a record that still stands today. Oliver worked with industrial partners on several high-efficiency concepts, including laser-grooved buried contact cells and interdigitated back contact structures, before leading the high-efficiency cell group from 2007-2008. In 2009, Oliver co-founded the Silicon Valley start-up company TetraSun which was acquired by First Solar in 2013 for their launch of crystalline silicon solar cell production. He has five issued patents and is an active peer-reviewer for several journal publications and the IEEE Photovoltaic Specialists Conference. Oliver received the Solar World Junior Einstein Award in 2006 and is a coawardee of the R&D 100 award of 2013.

King, Dave Wilt 40th IEEE PHOTOVOLTAIC SPECIALISTS CONFERENCE IN MEMORIAM John “Bill” Yerkes, a solar pioneer considered the “father of terrestrial PV”, died on January 29, 2014 in Santa Barbara from an adenocarcinoma. He was 79. Yerkes was an innovator and entrepreneur in PV for his entire life. He got his solar start as designer/manager of the Boeing Spacecraft test facility in Kent, WA. His supplier of sun-simulators, Spectrolab, hired him as General Manager to further develop flashers and search lights. As President, he led the development of solar arrays for Apollo 11 and his signature – among other key contributors’ - is still on the moon. When he left Spectrolab, Yerkes looked for ways to use solar energy on earth and founded Solar Technology International in 1973, where he scaled up low-cost processes such as POCl diffusion and screen printing. The purchase by oil giant Atlantic Richfield in 1979 allowed Yerkes’ company to become the world’s #1 cell and module producer out of Chatsworth and Camarillo, CA, where today’s essential solar module components were born. Markets included an alternative to thermoelectric power for telecom, aids to navigation, cathodic protection, vaccine refrigeration, water pumping and lighting in developing countries. Charlie Gay, who was VP of R&D under Yerkes and later ARCO Solar’s President recalls “Bill was magical. His raw, positive enthusiasm was contagious.” ARCO Solar’s ownership transitioned over the years to Siemens, Shell and 10 years ago to German giant SolarWorld, who still runs the largest solar cell and panel production in the USA out of Hillsboro, OR. In the early 90’s, Yerkes returned to Seattle to build Boeing’s High Tech Center and later to lead the power systems division of Teledesic’s ambitious broadband satellite constellation program. More recently, Yerkes co-founded Solaicx to develop novel continuous-growth Czochralski pullers delivering record productivity, and its ingot production operation in Portland, OR, is still growing today under Sun Edison’s ownership. Yerkes’ passion beyond solar included wine and great food, art, Formula 1 and his family. His natural hands-on skills and just-do-it attitude inspired many people to become passionate about solar and launch careers in photovoltaics. Richard Swanson, SunPower Corp.’s founder and long-time friend says “Bill had a unique ability to form lifelong friendships with his former employees and partners.” Yerkes is survived by his wife Sara, his daughter Kari Hummel and three grandchildren.

This area has gone through a complete transformation, drawing together expertise from chemistry, materials, physics and engineering to better match with ongoing exciting developments in this interdisciplinary field of organic PV. Moreover we strengthened the Technical Program by early involvement and announcement of more than 40 Featured Speakers and by introducing 13 joint sessions between various Areas. This year the PVSC-40 received a record number of more than 1100 abstracts which lead to a Technical Program of more than 360 Oral presentations, and more than 670 Poster presentations. Besides publications of papers in the Conference Proceedings, we are continuing the very popular option of offering authors who have submitted particularly high quality PVSC review abstracts to submit their research results as a manuscript to IEEE Journal of Photovoltaics (J-PV). This path allowed 155 authors to enjoy both the PVSC conference experience as well as receiving a peer review citation from a highly regarded journal. On behalf of the Technical Program Committee I wish you a great PVSC-40!

New technologies for advanced III-V multijunction solar cell architectures are presented in this area, since materials science is the basis for continuous improvements in the understanding and further development of III-V solar cell structures. III-V multijunction solar cells are the basis for the growing terrestrial market of high-concentration photovoltaics and concentrator silicon solar cells are the basis for systems in the low and medium concentration range. Area 3 covers all aspects of concentrator photovoltaics (CPV) system development including primary and secondary optics, solar cell receivers, module components, trackers, modules and CPV power plants. Reliability is an important aspect for this growing industry as well as market development, financing, power prediction, industry standards, balance of systems (BOS) and installation-related issues. In the field of low and medium concentration, high efficiency silicon solar cells offer interesting applications. Sub-Area Chairs Marc Stan (Emcore Photovoltaics, USA), Scott Burroughs (Semprius, USA), Daniel Biro (Fraunhofer ISE, Germany) 40th IEEE PHOTOVOLTAIC SPECIALISTS CONFERENCE AREA 4 OVERVIEW CRYSTALLINE SILICON PHOTOVOLTAICS Chair: Stefan Glunz, Fraunhofer ISE, Germany Co-Chairs: Ron Sinton, Sinton Instruments, USA Mariana Bertoni, ASU, USA Donghwan Kim, Korea University, Korea Area 4 Description Crystalline silicon photovoltaics is the dominant solar cell technology, with a market share of around 85% in 2012. Silicon is non-toxic and abundantly available in the earth’s crust; silicon PV modules have proven their long-term stability over decades in the field. The price reduction of silicon modules in the last 30 years can be described very well by a learning factor of 20%. Due to strong competition, this price decline was even stronger in the last years, resulting in module prices well below $1/W. This is an excellent situation for customers and PV installers, but rather challenging for producers of silicon solar cells and modules. Thus, cost reduction is still a major task. The cost distribution of a crystalline silicon PV module is clearly dominated by material costs, especially by the cost of the silicon wafer. Therefore, besides improved production technologies, the efficiency of the cells and modules is the main leverage to bring down the cost even more, especially when considering the full levelized cost of PV electricity. Area 4 of the 40th IEEE PVSC presents contributions reporting on all aspects of crystalline silicon technology, encompassing the whole value chain, as well as fundamental and scientific aspects.

OPV has continued to show tremendous progress in the past years. Solar cell efficiencies have rocketed to well above 10% and operating lifetimes have reached more than 10 years. Based on abundant materials and scalable coating technologies, OPV shows potential for low-cost, lightweight, and flexible solar power generation. Based on these prospects, many companies around the world are putting considerable efforts towards commercializing OPV. Organic photovoltaics – a prime example of interdisciplinary research drawing together expertise from chemistry, materials, physics, and engineering – will soon have to prove its viability in the market. Despite this remarkable progress, much of the underlying physical processes and their limitations have yet to be better understood. Similarly, scale-up in manufacturing volume has proven challenging for fast progress towards commercialization. The goal of this focus area is to address these issues, ranging from fundamental science to technological advances.

Almost of all spacecraft are powered by PV generators, and thus advances in space PV technologies contribute significantly to improvement of spacecraft performance. Space engineering including PV is one of the most important key technologies which contribute to national security. On the other hand, the size of space industry is not sufficient to stand and maintain activities in a country or an area. Therefore, we should compete and collaborate at the same time in this particular area. Area 7 of this conference will offer such opportunity for the competition and also collaboration, owing to your contributions!

Measurements are needed at all different levels of R&D and production – from investigating the operating principles of solar cells to developing standards for the performance of installed photovoltaic (PV) systems. The relationship between structure, physical properties, and the resulting PV performance is a challenge in materials science and engineering. Reliable and precise determination of the efficiency and thus power of solar cells and PV modules is crucial for the successful widespread deployment of PV and an ongoing challenge for flat-plate and concentrating PV technologies. Area 8 present the latest full range of scientific and technological challenges in the field of characterization of photovoltaics.

The world requires safer PV modules with more embedded services, including safety switch disconnect, ground-fault protection, monitoring services, maximum power point (MPP) trackers, power optimizers or micro-inverters. New materials for PV modules are introduced on a regular basis and require new testing methods for characterization. New assembly technologies are proposed. PV module modeling is getting more sophisticated including mechanical, thermal and electrical models, sometimes combined. Customers require better energy prediction and energy rating of the modules. Papers that describe advancement in PV module design, technology and modeling to improve cost, safety, energy performance, monitoring, are sought in this Area. This Area also presents papers related to improvements in manufacturing along the entire production chain of PV, from raw material to modules, including automation, inline monitoring, statistical process control, manufacturing plant design, cost models and cost prediction.
