Abstract:
Perovskite materials useful in the manufacture of photovoltaic cells are provided. The perovskite materials have the formula AB′ 0.5 B″ 0.5 X 3  or A′ 0.5 A″ 0.5 B′ 0.5 B″ 0.5 X 3 , wherein A, A′, and A″ are organic or inorganic cations, X is a halogen ion, B′ is tin, and B″ is germanium. Embodiments of the mixed tin and germanium halide perovskite materials possess a direct bandgap within the optimal range of 0.9-1.6 eV and have an optical absorption spectrum that is comparable to the state-of-the-art methylammonium lead iodide perovskites. The perovskite materials provided herein have been formulated to be lead-free.

Claim (Index 8):
The perovskite material of  claim 1 , wherein X is iodide.
