facade
ertex solar sat down in 2004 and set a clear goal to satisfy, as much as possible, the wishes for
architectural integration of photovoltaics into the building envelope. Some references can be
found on our website www.ertex-solar.at/cms/projects
Technically, today, all hurdles regarding electrical certi cation, but also the structural
constraints in the form of broad-based certi cates and approvals, have been mastered.
As before, however, the optical integration possibilities of photovoltaic elements into the
building envelope are often not suf cient. The BIPV modules in laminated safety glass from
ertex solar already offer in their different forms and styles (eg insulated glazing), module
dimensions and shapes, degree of transparency and types of solar cells, a wide spectrum of
possibilities. However, the colour design, in combination with as much a homogeneous
appearance as possible, especially when using crystalline solar cells, was still generally far
from being satis ed by the photovoltaic industry.
Photovoltaics for architecture.
Architecture for photovoltaics.
ertex solar has, therefore, with specialists in the architecture industry, but also experts from
the glass and PV sector, instigated a program to develop new modules in terms of their
appearance. These are primarily photovoltaic modules based on crystalline solar cells in a
variety of colours and with maximum optical homogeneity. In doing so, architects and façade
planners now have available to them a completely new photovoltaic module, that as
conventional façade elements meets their needs in terms of aesthetics and design freedom, but
is symbiotically combined with solar energy production.
In principle there are a variety of possibilities available, as each layer of the module from the
front glass surface to the reverse side of the glass can be textured and coloured. To name but a
few, LSG design front glazing with different patterns and degree of transparency, printed
reverse sides, coloured front glazing and encapsulated lm, textured front glazing, coloured and
semi-transparent solar cells and coloured solder joints can be realised.
Coloured panels with a high homogeneity, in which the solar cell structure is hardly perceptible,
is only possible through a combination of colouring and texturing different module layers. As a
rst step, a matrix was developed adhering to all sensible and realisable combinations. On the
basis of this decision made, pattern modules were produced, whereby the solar cells were
subjected to a particularly narrow performance grading and were characterised on their
performance before use in the cell asher. In this project, based on the module pattern, much
could be investigated and a variety of questions answered. Which combination of colouring and
structuring carries the highest homogeneity? Which colours can be achieved? What are the
effects upon the solar cells and the module yield through different shading structures, colours
and degree of transparency?
LSG-DesignPV
With help from measurement results, nally, a mathematical model was created which allows for
the calculation of module ef ciency for any colour and degrees of transparency, to save time in
the future for cost-intensive module test series and asher measurements. For a concrete
project we can, for your individual module choice, calculate the corresponding performance
data, at your ngertips.

ertex-solar is a company of ERTL GLAS AG, one of the leading producers of laminated safety glass (LSG). This LSGtechnology, in combination with the creativity and magnitude of ertex-solar's photovoltaic modules, opens up
completely new possibilities for architectural façade design.
ertex solar therefore sees itself as a partner for all architects who wish to know how to perfectly combines aesthetics and
solar energy. The XL-size solar modules in laminated safety glass technology are produced in special runs in one of the
world's most modern plants in Amstetten (Lower Austria). The extensive machinery and facilities in their own glass
processing centre offers individual custom-made products and limitless diversity of variants.
