Bandgap Tunable Two-Step Vapor-Deposited Perovskite Absorbers for Perovskite-Silicon Tandem Solar Cells

Year: 2026

Type: article

Abstract: We report a two-step thermal evaporation-close space sublimation deposition method for tunable bandgap lead halide perovskites with single junction solar cell efficiencies exceeding 20%. These absorbers are integrated into perovskite-silicon tandem solar cells with stabilized efficiencies of >29%.
