PURPOSE:To effectively utilize the incident light on both surfaces by providing semiconductors having P-N junctions or Schottky barriers and output electrodes on both sides of a substrate whose both surfaces indicate conductive porperty. CONSTITUTION:On both sides of a stainless steel plate 1, N layers 2, I layers 3, and P layers 4 are layered by the aid of amorphous Si. The layers are formed in a sequential process by changing the gas supply. Transparent electrodes 5 are deposited or the entire surfaces of the layers 4, and comb-shaped current collecting electrodes 6 are provided. By the incidence of the solar light 7, a voltage is generated between the substrate 1 and both electrodes 6. In this constitution, the output can be increased or the required area can be reduced. |
