Highly efficient sandwich design thin film luminescent solar concentrators based on blue and green emissive MAPbBr3 perovskites nanostructures

This study deals with the optimally designed blue and green emissive MAPbBr3 perovskite nanostructures (PNSs). Later PNSs were utilized as fluorescent material in a sandwich-design thin film luminescent solar concentrator (SD-TLSC). The fabricated SD-TLSC exhibits high performance with an impressive optical efficiency of 5.75% and a high average visible transmission (AVT) of 85.7%, which is the two-fold enhancement of the conventional single thin film LSC configuration. The high performance of the SD-TLC is induced by effective solar radiation absorption in the entire wavelength ranges, which is attributed to its unique morphology that exhibit different PL emission. These ground-breaking results pave the way for the potential practical use of perovskite-based SD-TLSC as solar windows, marking a major advancement in the field of building-integrated photovoltaic (BIPV). © 2023 Elsevier B.V.
