PURPOSE:To improve the photoelectric conversion efficiency of a photoelectric converter by using a specific colorless transparent polyimide film as a substrate, and irradiating a light from the substrate. CONSTITUTION:In a photoelectric converter having a photoelectric conversion element for converting optical energy into electric energy on a substrate, a colorless transparent light transmission polyimide film is employed as a substrate. The used colorless transparent polyimide film is formed of polyimide which mainly contains repetition unit represented by the formula (I). In the formula (I), X1-X4 are-H,-CH3-C2H5,-NO2,-F,-COOH or-Cl. Thus, the colorless transparent polyimide film is used as the substrate, and a light is irradiated from the substrate side, i.e., the side having excellent quality to remarkably improve the photoelectric conversion efficiency. |
