Title:
PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/092066
Kind Code:
A1
Abstract:
This photoelectric conversion element (10) comprises an electroconductive layer (2), a photoelectric conversion layer (3), and an opposing electrode (8), wherein at least the photoelectric conversion layer (3) is filled with an electrolyte. In the photoelectric conversion layer (3), a colorant made of a compound having one thiocyanate group and/or a colorant made of a compound having no thiocyanate group are/is adsorbed on a porous semiconductor layer made of a semiconductor material. The electrolyte includes pyrazole and/or a pyrazole derivative.
