WIPO Patent Application WO/2010/098311

Kind Code:

A1

Abstract:

Disclosed is a photoelectric conversion element of excellent durability. The disclosed photoelectric conversion element (100) is equipped with a pair of electrodes (10, 20) that face one another, a porous oxide semiconductor layer (3) provided on one of the pair of electrodes (10, 20), an electrolyte (5) disposed between the pair of electrodes (10, 20), and a sealing part (14) that connects the pair of electrodes (10, 20) and envelopes the porous oxide semiconductor layer (3) and electrolyte (5). At least a portion of the sealing part (14) is composed of an inorganic sealing part (14b) which is made from an inorganic material formed on the surface of at least one of the pair of electrodes (10, 20), and a resin sealing part (14a), which is made from a material that includes a resin and is connected with the inorganic sealing part (14b) along the direction in which the pair of electrodes (10, 20) are connected. The region (S2) of the surface of the inorganic sealing part (14b) that is closer to the electrolyte (5) side than the region (S1) that is connected with the resin sealing part (14a) is covered by a protective resin layer (17) that is resistant to the electrolyte (5).
