Transparent solar cells and modules
"The heart of a fool is in his mouth, but the mouth of a wise man is in his heart."
(Benjamin Franklin)

Transparent solar modules offer probably the most attractive BIPV sollutions. Modules with different transparency rates and/or different technologies are available on the market. Most common they consist of transparent crystalline cells, very often are also modules with transparent back side and with standard crystalline cells. Another interesting sollution are thin film transparent amorphous modules. Transparent modules can be used as window glazing in usual windows, sunspaces, they can be integrated into roofs etc. Quite often they are also a part of shading devices whether movable or not. Such systems are also knows as "shadow-voltaic" systems. Transparent modules can be also part of energy efficient glazing, where they are used instead of usual glass. With coloured back side interesting architectural visual effects can be obtained. Such sollutions are often used in old architectural protected heritage buildings. Example of heritage building renovation with photovoltaic roof tiles you may also find in roof tiles section. Very attractive are also thin film modules because they offer some tailor made sollutions - different shapes or patterns within modules are possible. World's largest photovoltaic module with rated power 1500 W was presented on Intersolar fair in June 2005 (see photo above). Module is produced by austrian company Ertex Solar GmbH. Glass-glass laminate module is suitable for facade integration, atriums or large sunspaces.

Transparent modules as shading devices |
Transparent modules as glazing |
|
Transparent modules are often part of shading devices. Shading devices - like overhangs for example - can be fixed or movable. Manual tracking-combined with shadowing system, or automatic tracking systems can be realised. Very often they are realised as venetian blinds or classic awnings. Vertical ond horizontal shading devices are used in practice. If transparent modules are integrated into transparent roof or sunspace glazings they also offer some shading so additional shading devices are usually not necessary. Some shading devices you may find in pictures below. For details about shading calculation, shading analysis tools etc. please see shading section. |
Different types of transparent modules are used as glazing, most common crystalline as single glazing or double (low U-value)
insulation glass. Transparent modules can also be used in sunspaces and atriums. Example of renewed heritage building with transparent modules you may see on picture below.
