Luminescent downshifting coatings represent a cost-effective enhancement for semiconductor photovoltaic systems by amplifying solar cell power generation. Nanohybrid coatings were prepared by doping polymethyl methacrylate with green-emitting indium phosphide/zinc sulfide (InP/ZnS) quantum dots (QDs) using the spin coating technique. The samples were characterized by differential scanning calorimetry, transmission electron microscope, optical absorption, and fluorescence spectroscopy. The results indicated that the optimal film homogeneity and optical quality were achieved with a doping concentration of 0.12 wt%. Additionally, this concentration exhibited the highest tuned green emission, boasting a quantum yield of 76%. The power conversion efficiency of GaAs solar cells was significantly increased by 35.17% due to the down-conversion of UVA photons into the spectral sensitivity range. Additionally, by increasing QDs concentration, the coatings exhibited outstanding resistance to heat and ultraviolet radiation. The results of this study are significant for countries with hot and sunny climates, as they contribute to the advancement of eco-friendly energy solutions that align with the goals of sustainable development.
