We report systematic design and formation of plasmonic perovskite solar cells (PSCs) by integrating Au@TiO2 core-shell nanoparticles (NPs) into porous TiO2 and/or semiconductor capping layers. The effects in the formed PSCs are examined. most efficient configuration is obtained incorporating NPs both layers, which increases power conversion efficiency (PCE) from 12.59% to 18.24%, demonstrating over 44% enhancement, compared with reference device without metal NPs. PCE enhancement mainly attributed short-circuit current improvement. nanosphere photovoltaic composites explored based on combination UV-vis absorption spectroscopy, external quantum (EQE), photocurrent properties, photoluminescence (PL). addition nanospheres increased rate exciton generation probability dissociation, enhancing charge separation/transfer, reducing recombination rate, facilitating carrier transport device. This study contributes understanding also provides a promising approach for simultaneous photon energy electron management.
