Abstract

Controlled incorporation of PbI2 improves wide-bandgap perovskite film quality, crystal growth, and carrier dynamics. The optimized Cs0.18FA0.82Pb(I0.6Br0.4)3 perovskite solar cell demonstrated an impressive performance of 19.01%, achieving a remarkable open-circuit voltage of 1.32 V under sunlight. Under indoor lighting conditions, the tailored perovskite solar cell achieved a high indoor PCE.
