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.


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.


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.




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. 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. 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 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 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. 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.
