Abstract

The present study analyzes the implementation of an anti-reflective coating based on silver nanoparticles to improve the efficiency of ultrathin amorphous silicon solar cells. The absorption limitations in these cells are addressed and the impact of nanoparticle-induced optical scattering on enhancing light harvesting is explored. Through the Finite Differences in the Time Domain (FDTD) method, the interaction between incident radiation and nanoparticles is simulated, evaluating its influence on the amplification of the electric field and the conversion efficiency. The results show that the optimal arrangement of the nanoparticles allows reducing optical losses and increasing the efficiency of the device. It is concluded that the integration of metallic nanoparticles is a promising strategy to optimize the performance of thin film solar cells, which opens new possibilities for the development of more efficient and economically accessible photovoltaic technologies.
