Document Type and Number:
WIPO Patent Application WO/2022/145283
Kind Code:
A1
Abstract:
Provided is a see-through solar cell having high photoelectric conversion efficiency. A solar cell 1 according to an aspect of the present invention comprises: a semiconductor substrate 10 formed as a flat plate and having a plurality of light-transmitting openings 11 extending therethrough in a thickness direction thereof; a first semiconductor layer 20 stacked on one major surface side of the semiconductor substrate 10; a second semiconductor layer 30 stacked on another major surface side of the semiconductor substrate 10; a first electrode 60 stacked on the first semiconductor layer 20; and a second electrode 70 stacked on the second semiconductor layer 30. The inner circumferential surface of the light-transmitting openings 11 includes a first circumferential surface portion 12 positioned closer to the first semiconductor layer 20, and a second circumferential surface portion 13 positioned closer to the second semiconductor layer 30 and having a surface property different from that of the first circumferential surface portion 12.
