PURPOSE:To obtain a solar cell high in energy conversion efficiency where electron-hole pairs generated near to the surface of a window layer are efficiently caught as a photocurrent by a method wherein a transparent first electrode layer, a ZnS thin film, a CdS thin film, a light absorbing semiconductor layer 3, and a second electrode layer are successively laminated on a transparent insulating board. CONSTITUTION:A transparent first electrode layer 12 of ITO or SnO2 or the like is formed on a transparent insulating board 11 such as a glass board, a ZnS thin film 13a is formed thereon as thick as 0.2mum or so, and a Cd thin film 13b is formed thereon as thick as 0.2mum or so. Then, a P-type CdTe thin film or a P-type CuInSe2 thin film is formed as thick as 3mum or so to serve as a light absorbing semiconductor layer 14, and a second electrode layer 15 of Au or Ni or the like is provided thereon. |
