PHOTOELECTRIC CONVERSION ELEMENT, PROCESS FOR PRODUCING SAME, OPTICAL SENSOR, AND SOLAR CELL

摘要

A photoelectric conversion element including a photoelectrode (101) constituted of a porous semiconductor layer (106) and a transparent electrode (107) and a counter electrode (102) disposed opposite the photoelectrode (101), wherein a nitroxyl radical compound represented by general formula (1) is mainly contained between the photoelectrode (101) and the counter electrode (102). (In general formula (1), A represents a substituted or unsubstituted aromatic group and optionally includes one or more oxygen, nitrogen, sulfur, silicon, phosphorus, boron, or halogen atoms, and the aromatic group may be one formed by fusion of a plurality of aromatic groups.)
