Unique Properties of Halide Perovskites as Possible Origins of the Superior Solar Cell Performance

Halide perovskites solar cells have the potential to exhibit higher energy conversion efficiencies with ultrathin films than conventional thin‐film solar cells based on CdTe, CuInSe2, and Cu2ZnSnSe4. The superior solar‐cell performance of halide perovskites may originate from its high optical absorp...

Description
Summary:Halide perovskites solar cells have the potential to exhibit higher energy conversion efficiencies with ultrathin films than conventional thin‐film solar cells based on CdTe, CuInSe2, and Cu2ZnSnSe4. The superior solar‐cell performance of halide perovskites may originate from its high optical absorption, comparable electron and hole effective mass, and electrically clean defect properties, including point defects and grain boundaries.
