Luminescent solar concentrators (LSCs) concentrate sunlight incident from a large area to a smaller one, thereby reducing photovoltaic (PV) materials consumption and enabling building-integrated PV. Reduced-dimensional metal halide perovskite nanoplatelets (PNPLs) have recently emerged as candidates for low-loss large-area LSCs, since they combine the optoelectronic properties of perovskite materials with reduced absorption-luminescence spectral overlap. Prior LSC studies based on PNPLs used bromine-based perovskites, and their absorption spectral range was limited to wavelengths shorter than 520 nm. We engineered the precursor chemistry of iodine-based perovskites to realize a room-temperature synthesis of PNPLs that exhibit a substantially uniform distribution of quantum wells. The high photoluminescence quantum yield led to an optical conversion efficiency that is 1.3× higher than in the best previously reported room-temperature-fabricated perovskite LSCs.
