Abstract

This research explores the enhancement of power conversion efficiency in thin-film organic–inorganic halide perovskite solar cells by embedding plasmon-enhanced coupled spherical core–shell nanoparticles within the absorber layer. To address the limitations of traditional metallic nanoparticles, core–shell structures were employed to improve both chemical and thermal stability. Electromagnetic field distributions and optical characteristics were analyzed by solving Maxwell’s equations, while the electrical performance parameters were obtained through numerical simulations of the Poisson and continuity equations. Under optimized conditions, the perovskite solar cell demonstrated a notable performance, achieving an open-circuit voltage (Voc) of 1.056 V, short-circuit current density (Jsc) of 22.885 mA/cm², fill factor (FF) of 85.70%, and a power conversion efficiency (PCE) of approximately 21%. Moreover, the use of a thinner perovskite absorber layer contributed to a reduction in lead-related toxicity. This study provides a comprehensive framework for incorporating plasmonic coupled core–shell nanoparticles into high-efficiency thin-film perovskite solar cells. It underscores the dual advantage of enhanced photovoltaic performance and reduced environmental impact, paving the way for more sustainable solar technologies.
