Document Type and Number:
WIPO Patent Application WO/2020/250521
Kind Code:
A1
Abstract:
Embodiments described herein provide a solar cell, a multi-junction solar cell, a solar cell module, and a solar power generation system with improved characteristics. The solar cell according to an embodiment includes a first electrode being transparent, a photoelectric conversion layer mainly including cuprous oxide on the first electrode, an n-type layer being a metal oxide layer containing Zn and Si on the photoelectric conversion layer, and a second electrode being transparent on the n-type layer.
