%X The use of metal-halide perovskites in photovoltaic applications has become increasingly attractive due to their low-temperature manufacturing processes and long charge-carrier lifetimes. High-bandgap perovskite solar cells have potential for indoor applications due to their efficient absorption of the spectrum of light-emitting diodes (LEDs). This study investigates the performance of high-bandgap perovskite solar cells under a wide range of lighting conditions, including a commercially available white LED lamp with a 5–40 000 lx illuminance range and a standard 1 sun reference. The performance of CH3NH3PbI3-based perovskite solar cells to CH3NH3Pb(I0.8,Br0.2)3 solar cells with varying electron transport layers (ETL), including PCBM, PCBM:CMC, and CMC:ICBA fullerene combinations, is compared. Because the spectral response of perovskite solar cells covers the white LED spectrum very well, the major performance difference is related to the open-circuit voltage and fill factor. The cells with the CH3NH3Pb(I0.8,Br0.2)3 absorber layer and the CMC:ICBA ETL demonstrate superior open-circuit voltage and therefore a high efficiency above 29% at 200–500 lx, typical for indoor lighting.
