Title: Alloyed halide double perovskites as solar-cell absorbers

Abstract

An alloyed halide double perovskite material, an alloyed halide double perovskite solar-cell absorber and solar cells constructed with such absorbers, the alloyed halide double perovskite material having the formula A2B1-aB′1-bDxX6, where A is an inorganic cation, an organic cation, a mixture of inorganic cations, a mixture of organic cations, or a mixture of one or more inorganic cations and one or more organic cations, where B is a metal, a mixture of metals, a metalloid, a mixture of metalloids, any mixture thereof, or is a vacancy, where B′ is a metal, a mixture of metals, a metalloid, a mixture of metalloids, any mixture thereof, or is a vacancy, where D is a dopant, and where X is a halide, a pseudohalide, a mixture of halides, a mixture of pseudohalides, or a mixture of halides and pseudohalides, and where x=a+b.
