Enhancing Wide-Bandgap Triple-Halide Perovskites for Tandem Solar Cells by 0.5% Formate and Zn(II) Doping
Abstract
The intrinsic properties of wide-bandgap, triple-cation, triple-halide perovskites, like (Cs0.21FA0.74MA0.05)Pb(I0.81Br0.14Cl0.05)3, can be improved by simultaneous doping with zinc cations (0.5%) as well as formate anions (0.5%). Photoluminescence quantum yields (up to 14% on quartz), as well as photoluminescence lifetimes (up to ~7 µs on quartz), indicate improved optical properties. Based on photoluminescent properties, the optimal total doping concentration of zinc ions (Zn(II)) and formate anions (Fo−) is determined to be 1% relative to Pb(II).
