Photovoltaic, Thin Film, Non Silicon
As an alternative to silicon (Si), other semiconductor materials can be used for thin film solar cells. They have been proven to have greater efficiency than thin film amorphous silicon.

Cadmium Telluride (CdTe) has a conversion efficiency of about 16%.

Copper-Indium Gallium Selenide (CIGS) has a conversion efficiency of about 20%.
