摘要:
Provided is a tandem-type thin film silicon solar cell module having a structure wherein an intermediate layer is arranged. The module suppresses a problem of a current leak through the intermediate layer and has high light conversion efficiency by suppressing expansion of an ineffective area not contributing to power generation. A method for manufacturing such module is also provided. The module has a structure wherein a separating groove is arranged between the intermediate layer and a connecting groove, the separating groove is embedded with a crystalline silicon film, and a separating member does not exist between the separating groove and the connecting groove.

摘要:
A photoelectric converter includes a transparent substrate having a photoelectric converting element provided on a surface opposing a document relating to reading of image information, a transparent support for supporting the substrate, and a light source provided on a surface of the support opposite to a supporting surface for the substrate. Light emitted from the light source is radiated on a document through the support and the substrate, and reflected light is received by the photoelectric converting element.
