Metal nanoparticles have demonstrated outstanding properties in photovoltaic devices through introducing localized surface plasmon effects. The performance of Perovskite solar cell (PSC) by incorporating Ag@P4VP NPs was investigated systematically. The plasmonic enhancement effects are explored based on the combination of UV-visible absorption spectroscopy and Scanning Electron Microscope (SEM). The performance, especially the short circuit current density (Jsc), and open circuit voltage (Voc)of the PSC containing Ag@P4VP NPs was significantly affected. The power conversion efficiency (PCE), Jscand Vocofthe reference device shows a value of 3.80 %, 11.04 mAcm?2and 0.85 V. Upon introducing AgNPs@P4VP, a PCEof 5.69 %, Jscof 12.61 mAcm?2and Vocof 0.88 V were recorded, which improved the PCE? 39.4 % over that of the standard device. The improvement is attributed to an increase in photocurrent density due to enhanced light harvesting by silver nanoparticles.
