Professor Samson A. Jenekhe Tuesday, April 19, 2016 Departments of Chemical Engineering & Chemistry Chemistry Room #1315 3:30 PM University of Washington Organic Photovoltaics Beyond Fullerenes Seminar sponsored by: UW-Madison MRSEC Finding a way to meet the energy needs of the world’s growing population via an environmentally sustainable paradigm is among the grand challenges facing society. Although the sun represents the most abundant potential source of pollution-free energy on earth, electrical power from current photovoltaic technologies is too expensive compared with that from fossil fuels. Organic photovoltaics (OPVs) field aims to develop novel organic materials and devices that could potentially revolutionize solar energy conversion technologies, to make them cheaper than fossil fuels. Fullerene-based electron acceptors have provided the foundation for advances in fundamental understanding of charge photogeneration, charge transport, morphology and practical developments in OPVs in the last 20 years. New electron-acceptor materials are long sought to overcome the small photovoltage, high-cost, poor photochemical stability, and other limitations of fullerene-based organic photovoltaics. Our years of efforts have recently led to major advances in developing nonfullerene OPVs that promise far superior performance and ruggedness. .
