摘要： A solar cell having high conversion efficiency and excellent flexibility is realized. A mica substrate or laminated mica substrate is used as substrate 1. The mica and laminated mica have high insulating property and heat resistance temperature, which can be selenized at an appropriate treatment temperature through vapor-phase selenization process, high conversion efficiency and excellent flexibility resultantly suitable for mass-production can be obtained. On the other hand, because the surfaces of the mica and laminated mica have large surface roughnesses, it is impossible to induce leakage to obtain high conversion efficiency in the case where a chalcopyrite based light absorbing layer 6 is simply formed. In the present invention, an intermediate layer 2 of ceramic based material and binder layer 4 are interposed between the mica substrate 1 and a molybdenum electrode 5. By providing the intermediate layer 2 and binder layer 4, surface coating property is enhanced and a solar cell having high conversion efficiency can be realized.

摘要： A first electrode layer 14 is formed on a mica substrate 54, and then first scribe portions 64 are disposed. Next, a light absorbing layer 16 and a buffer layer 18 are disposed on the first electrode layer 14, and through holes (second scribe portions 66) which penetrate from the upper end face of the buffer layer 18 to the lower end face of the mica substrate 54 are formed in a spot-like manner.
