The most basic form of a solar cell contains a light-absorbing semiconductor having hole and electron selective contacts of fixed energy bandgap for carrying extraction and separation of charges. The absorber materials used in solar cells are nontoxic, abundant, stable and its characteristics are well known. The available technologies, i.e., thin-film and crystalline depend solely on the manufacturing equipment and knowledge of solid forms of Si as well as know-how from the microelectronics industry.
