Title:
PHOTOELECTRIC CONVERSION ELEMENT, SOLAR CELL, AND POSITIVE-HOLE TRANSPORT MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/053968
Kind Code:
A1
Abstract:
Provided are: a photoelectric conversion element and solar cell which contain a perovskite compound in a photosensitive layer thereof and have a high fill factor; and a positive-hole transport material. This photoelectric conversion element has a conductive support body which forms a first electrode, a photosensitive layer containing a light-absorbing agent between the first electrode and a second electrode facing the first electrode, and a positive-hole transport layer that is layered on the photosensitive layer, wherein the light-absorbing agent contained in the photosensitive layer includes at least a compound having a perovskite crystal structure, and the positive-hole transport layer contains a positive-hole transport material represented by a specific formula.
