Perovskite solar cells (PSCs) have attracted significant scholarly attention in the field of photovoltaics due to their simple fabrication process and low cost. However, their potential for commercial use is limited by issues such as low power conversion efficiency (PCE) and instability. In this study, an approach for enhancing both the performance and life time cycle of perovskite solar cells (PSCs) by integrating biosynthesized silver nanoparticles (AgNPs) into the device structure was demonstrated. Unlike previous works that mainly focus on chemical synthesis of plasmonic nanoparticles, this method employs an eco-friendly biosynthesis route, offering a sustainable alternative. PSCs fabricated with varying AgNP concentrations (0–250 µL) exhibited significant improvements, with power conversion efficiency (PCE) increasing from 2.65% to 5.35%, and device lifetime extended by 69% relative to the control device. The observed enhancement is attributed to the plasmonic effects of AgNPs, which enhance light absorption, improve charge carrier extraction, and increase conductivity. This work highlights a promising strategy for the development of more durable and efficient PSCs through green nanotechnology.
