Abstract

Official abstract text for this publication.

The present disclosure provides a photoabsorber containing: a perovskite compound represented by the composition formula ABX 3 , where A represents a monovalent cation, B represents a divalent cation including a Sn cation, and X represents a halogen anion; and a trivalent cation of a Group 3 element.

First claim

Opening claim text (preview).

The invention claimed is: 1. A solar cell, comprising: a first electrode; a second electrode; and a photoabsorber layer containing a trivalent cation of a Group 3 element and a perovskite compound represented by the composition formula ABX 3 , where A represents a monovalent cation, B represents a divalent cation including a Sn cation, and X represents a halogen anion, wherein the photoabsorber layer is disposed between the first electrode and the second electrode, at least one selected from the group consisting of the first electrode and the second electrode is light-transmissive, and the Group 3 element is selected from the group consisting of yttrium and scandium. 2. The solar cell according to claim 1 , wherein a molar ratio of the trivalent cation to the Sn cation is more than 0.0002 and not more than 0.02. 3. The solar cell according to claim 2 , wherein the molar ratio of the trivalent cation to the Sn cation is not less than 0.002 and not more than 0.02.
