太陽電池
Document Type and Number:
Japanese Patent JP7429881
Kind Code:
B2
Abstract:
The present disclosure provides a technique for increasing the conversion efficiency of a tin-based perovskite solar cell. A solar cell according to the present disclosure includes a first electrode, a second electrode, a photoelectric conversion layer located between the first electrode and the second electrode, and a first electron transport layer located between the first electrode and the photoelectric conversion layer, in which at least one selected from the group consisting of the first electrode and the second electrode is translucent, the photoelectric conversion layer contains a perovskite compound composed of a monovalent cation, a Sn cation, and a halogen anion, and the first electron transport layer contains a niobium oxide halide.
