Abstract: A solar-cell absorber layer for use in solar cells including tandem solar cells, is made of a metal-halide double perovskite material. The metal-halide double perovskite material has the formula A2BB′X6, where A is an inorganic cation, an organic cation, or a mixture of organic and inorganic cations where B and B′ are metals, and where X is a halide or a mixture of halides. For example, A can be Cs, Rb, K, Ba, CH3NH3, (NH2)2CH, or a mixture where B is Bi, Ag, Sn, In, Sb, Cu, Na, K, or Au of a predetermined oxidation state, and where B′ is Bi, Ag, Sn, In, Sb, Ga, Cu, or Au of various oxidation states, and where X is Br, I, Cl, F, or a mixture. One example of the metal-halide double perovskite material is Cs2BiAgBr6.
