Abstract

We demonstrate a method to enhance the power conversion efficiency (PCE) of MAPbI 3 perovskite solar cells through localized surface plasmon (LSP) coupling with gold nanoparticles:CsPbBr 3 hybrid perovskite quantum dots (AuNPs:QD-CsPbBr 3 ). The plasmonic AuNPs:QD-CsPbBr 3 possess the features of high light-harvesting capacity and fast charge transfer through the LSP resonance effect, thus improving the short-circuit current density and the fill factor. Compared to the original device without Au NPs, a 27.8% enhancement in PCE of plasmonic AuNPs:QD-CsPbBr 3 /MAPbI 3 perovskite solar cells was achieved upon 120 μL Au NP solution doping. This improvement can be attributed to the formation of surface plasmon resonance and light scattering effects in Au NPs embedded in QD-CsPbBr 3 , resulting in improved light absorption due to plasmonic nanoparticles.
