Scientists do not still understand what goes on in the material that makes up solar cells. But scientists did happen to make this discovery. Solar cells are made from organic semi-conductors. Solar cells are blended with materials. 

But these solar cells only have a whopping 3 percent efficiency rate. This model created by these scientists will increase efficiency. It is a mathematical model, and will help in chemistry a lot.
