DYE-SENSITIZED PHOTOELECTRIC CONVERSION ELEMENT

摘要

The present invention provides a dye-sensitized photoelectric conversion element that is provided with a porous film containing ZnO as a principal ingredient and that has a high open-circuit voltage. Provided are: a working electrode substrate 10 provided with a transparent support substrate 1, a transparent electrode film 2, and a dye-carrying porous film 3 containing ZnO as a principal ingredient; a counter-electrode substrate 20 provided with a support substrate 5 and an electrode film 6; and an electrolytic solution 30 containing an iodine redox. The working electrode substrate 10 and the counter-electrode substrate 20 are disposed opposite each other with the electrolytic solution 30 sealed therebetween. The electrolytic solution 30 contains an iodide salt having a cation with a molecular weight of 125 g/mol or more.
