Photoelectric converter, and transparent conductive substrate for the same

Abstract

A highly durable photoelectric converter with excellent photoelectric conversion efficiency is prevented from resistance loss or lowering of photoelectric conversion efficiency and free from problems of corrosion and reverse electron transfer reaction. Specifically disclosed is a photoelectric converter (1) comprising a semiconductor electrode (11), a counter electrode (12), and an electrolyte layer (5) arranged between the electrodes. The semiconductor electrode (11) includes a transparent conductive substrate (10) including a transparent base (2), a conductive interconnection layer (3), and a metal oxide layer (30), and a semiconductor particle layer (4) arranged on the transparent conductive substrate (10). The transparent base (2) of the transparent conductive substrate (10) has a trench (3h) on one surface, and the conductive interconnection layer (3) is embedded in this trench (3h).
