ACCUMULATEUR SOLAIRE DE TYPE HUMIDE ET MODULE ACCUMULATEUR SOLAIRE DE TYPE HUMIDE

摘要

A wet-type solar battery (10) including a support (1) composed of a light transmissive material and a stack in which a conductive layer (2), a photoelectric conversion layer (4) containing a porous semiconductor, a porous insulating layer (5), and a counter electrode conductive layer (6) are stacked in this order is provided. The conductive layer (2) is divided into a first region (2a) including a portion where the photoelectric conversion layer (4) is to be formed on a surface thereof and a second region (2b) where the photoelectric conversion layer (4) is not to be formed. A protection film (9) for preventing internal short-circuiting, which is not greater in film thickness than the photoelectric conversion layer (4), is formed in at least a part around the photoelectric conversion layer (4) on the surface of the first region (2a).
