Perovskite-type compound and photoelectric conversion element

Abstract

Provided is a perovskite-type compound having high heat resistance. The perovskite-type compound comprising a composition represented by A(Pb1-xSnx)I3-yBry. The element A is one kind or two or more kinds of elements selected from the group consisting of Li, Na, K, Rb and Cs. In the composition formula, x and y belong to any of ranges (1) to (6) below: (1) 0.0≤x<0.0125 and 1.6≤y≤3.0; (2) 0.0125≤x<0.1 and 1.1≤y≤3.0; (3) 0.1≤x<0.3 and 0.8≤y≤3.0; (4) 0.3≤x<0.5 and 0.8≤y≤3.0; (5) 0.5≤x<0.7 and 0.8≤y≤2.8; and (6) 0.7≤x≤0.8 and 0.8≤y≤1.8.

Dependencies are inferred from the claim text.
