Hi partners! I found some interesting stuff. One Russian company developed photovoltaic panels based on silicon-polymer. There are two types of these panels. First is being producing serially and has characteristics not worse than conventional monocryslalline silicon panels and in some items panels of first type have advantages, f.e. in cloudy weather. Price is differed greatly. They ask for 0,5..0,6 Euro per 1 Watt. In other words 1 m2 of Russian panel costs 60 Euro against 320..340 Euro per common known one. Second type has been developed already and prepared to produce. Panels of the second type are also based on polymer and has 70% efficiency i.e. 1 m2 of this panel gives 600..700 Watt when illumination conditions are1000 Watt per 1m2. But this damned panel is too expensive: something about 1000 Euro per 1m2. Hopefully the price will be reduced in serial production. It’s the first point. The second one is that this panel is 7 times more effective then standard panel and correspondently it takes 7 times less effective area. So even alone panel is incredibly expensive the total price is awaited to be some times cheaper. I am interested in your opinion. Thanks.

Oleg,

A 70% efficient solar PV panel would necessarily operate on different physics from today's PV panels. Conventional PV panels have a response range from 0.4 to 1.1 micrometer (see http://en.wikipedia.org/wiki/Photodiode) but are highly sensitive only from 0.6 to 1.0 micrometers, much narrower than the solar spectrum which ranges from 0.3 to 2.5 micrometers. If the conversion efficiency for solar energy directly to electrical energy were truly 70%, this would truly be world-changing. I am skeptical.

Then the rights of intellectual property were registered it would be
planned to begin production of PV panels of such type.
