Transparent photovoltaic
The connecting leads are hidden in the metal frame. The photovoltaic cells generate energie from light of both sides. So, this module is also called Janus.  

Transparent photovoltaic

The connecting leads are hidden in the metal frame. The photovoltaic cells generate energie from light of both sides. So, this module is also called Janus.

This would bring a garden fence to about 100 W Peak per run meter.
Photovoltaic - Electric power direct from light Photovoltaic - Electric power direct from light
Even a far north situated industrial nation like Germany could produce a big part of the needed energy by the roofs of the houses. Photovoltaic has much potential.




  Photovoltaik fair Intersolar 2005 in Freiburg


Fair report from Intersolar in 2005 in Freiburg. In 3 parts. fair in general, only about photovoltaicand special part solar energie for Africa.

Double-sided photovoltaic half transparent: Janus Double-sided photovoltaic half transparent: Janus
This on both sides active photovoltaic offers new creation elements for the architecture. Maybe a garden fence or the balustrade for a patio.


Crystalline silicon in thin layer Crystalline silicon in thin layer
Much less consumption of silicon. Only 2 µ k instead of some 100 µm is the crystalline layer of this new thin layer module of Sharp thick.


Fashion color black: new photovoltaic with more achievement Fashion color black: new photovoltaic with more achievement
With an increase in output of the crystalline silicon cells also there came a color change. Instead of up to now blue gleaming, present the new cells in deep black.


Roof-integrated photovoltaic Roof-integrated photovoltaic
For what make a roof and integrate a photovoltaic? It is much eaiser, when the roof and the photovoltaikc are together delivered.


Sandwich roof with heat insulation and photovoltaic Sandwich roof with heat insulation and photovoltaic
Cross section by a ready roof element: Amorphous photovoltaic from Uni-Solar. Under it in 3 different strengths deliverable a foamed heat insulation.


Roof: Photovoltaic roof underside Roof: Photovoltaic roof underside
In the underside of a ready roof element are the energy connections of the photovoltaic. Today with this new technology one would produce many large photovoltaic roofs more cheap.


Roof renovation for big flat roofs Roof renovation for big flat roofs
1 m wide and up to 24 ms long are such ready roof elements in mono sandwich construction method. And the generated energy pays off the renovation completely by itself.


Round standing seam roof with photovoltaic Round standing seam roof with photovoltaic
The photovoltaic is already provided on the roof elements. Quick assembly of the finished part roofs allow a very inexpensive roof as well as favorable solar energie.


Progress with amorphous silicon cells Progress with amorphous silicon cells
The first modules of this size had only 10 watts till 1996. Then in 1997 I could test a 12 watts module. Now the technic has arrived at 18 watts.
