Organic & polymer solar cells are made from thin films (typically 100nm) of organic semiconductor such as polymer and small molecule compounds like poly phenylene vinylene, copper phthalocyanine a blue or green organic pigment and carbon fullerenes. The energy conservation efficiency of data using conductive polymer are low at 4-5% efficiency for the best cells to data. Though, these cells could be helpful in some applications where mechanical flexibility and disposability are significant. The invention of conductive polymer has leaded the development of much cheaper cells which are based on inexpensive plastics. However all organic solar cells made of data suffer from degradation upon exposure to UV light, and hence have lifetimes which are far too short to be viable. The conjugated double bond systems in the polymers, which take the charge, are all the time susceptible to breaking up when radiated with shorter wavelengths. Additionally, most conductive polymer, being highly unsaturated and reactive, are highly sensitive to atmospheric moister and oxidation, making commercial applications difficult.
