摘要 |
A photoelectric conversion element includes a substrate with an insulation layer having a metallic substrate and an electrical insulation layer formed on a surface of the metallic substrate, a diffusion prevention layer made of nitride and formed on the electrical insulation layer, an alkali supply layer containing an alkali metal element and formed on the diffusion prevention layer, a lower electrode formed on the alkali supply layer, a photoelectric conversion layer including a compound semiconductor layer and formed on the lower electrode, and an upper electrode formed on the photoelectric conversion layer. The electrical insulation layer includes an anodized film of aluminum, and the diffusion prevention layer prevents at least diffusion of the alkali metal element from the alkali supply layer to the substrate with the insulation layer.
