By judiciously engineering solvent and anti-solvent ratios during the preparation of precursors, Li et al. exploit solvent-Pb2+ coordination to control the multiple quantum well (MQW) distribution in perovskite nanoplatelets (PNPLs). They report 10 × 10 cm luminescent solar concentrator (LSC) devices based on PNPL/poly(methyl methacrylate) composites; these reach an optical conversion efficiency of 2.0%.
