PURPOSE: To form a uniformly rough surface having a high adhesion by inserting a light scattering polymer film between a second transparent electrode layer and a moistureproof film. CONSTITUTION: On one side of a plastic film substrate 1 a first electrode layer 2, thin film semiconductor layer 3 and second transparent electrode layer 4 are laminated. On the other side a third electrode layer 5 is formed and connected through throughholes to the layer 2 or 4. A light scattering polymer film having a rough surface is formed on the layer 4 of a solar cell and this laminate is held between a transparent moistureproof film 81 through a transparent adhesive agent layer 71 and moistureproof film 82 through an adhesive agent layer 72 formed on a third electrode layer 5. The layers 71 and 72 use nylon-12, etc. The film 6 is made by polymerizing a polymethyl methacrylate (PMMA) resin with a polymer different in refractive index and hardening so as to form a rough surface. Thus a uniformly rough surface having a high adhesion to the electrode layer or moistureproof film can be formed. |
