Although organic solar cells are just the solar cell based on the movement of electron-hole just like amorphous or crystalline silicon semiconductor. We are going to talk about a little bit about that why organic solar cells should be used. As by now we know that we want to reduce cost and what could be less costly compared to then going to a hardware store and buying two cans of paints. If you could buy it, mix them up and can make a solar cell by painting on something. It will be a very-very cheap technology. In practice of course nothing is simple and it turns out that if you go and try to make a cost estimate of organic solar cell it is a then crystalline silicon seems comparably easy and good cell. Its property of semi transparency of OPVs is used in many field and green house is one of them. The recent research shows that hetero junction based organic photovoltaic cells can separate many colour components of sun light. So by making specific compound, special purpose and mostly utilised colour can be separated out from the sun light which can be used in some other process. As in photosynthesis process plants requires mostly only red and yellow colour. So in sun light other colours can be used to generate the electricity whereas the silicon based solar cell completely block the sun light. Excepts this polymer based organic solar cells have some other important benefits in comparison of conventional silicon based solar cell, which will be discussed here in brief.

OPVCs (Organic Photovoltaic Cells), HOMO, LUMO, Polymer based organic cells, hetero junction, nano-crystalline silicon and CIGS (copper indium gallium selenide), OPVs material (say P3HT, PTB7, PCMB and ICBA) and Conjugated system in OPVs
