Title:
PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/168175
Kind Code:
A1
Abstract:
Provided is a photoelectric conversion element that is capable of selectively reflecting light as a result of the structure of the photoelectric conversion element itself. The photoelectric conversion element uses a semiconductor for converting light into electric power via the photovoltaic effect and is provided with: a semiconductor layer which comprises a semiconductor; a front side metal layer which is a metal layer formed on the surface of the semiconductor layer; and a rear side metal layer which is a metal layer formed on the rear surface of the semiconductor layer, wherein the front side metal layer, the semiconductor layer, and the rear side metal layer form a resonator having an MSM structure.
