摘要

This study explores using plasmonic nanoparticles to improve solar cell performance by enhancing light absorption and carrier generation. MATLAB simulations model the effects of localized surface plasmon resonance (LSPR) on the electromagnetic fields around these nanoparticles. The findings reveal significant increases in light scattering, spectral broadening, and absorption in the visible and near-infrared regions, crucial for efficient solar energy harvesting. The research focuses on gold and silver nanoparticles, demonstrating how LSPR optimizes light concentration and scattering into the solar cell’s active layer. The results include enhanced absorption in visible and near-infrared regions due to LSPR, leading to improved light harvesting and greater solar cell efficiency with optimized nanoparticle configurations. The study employs Gaussian functions for simulating wavelength-dependent absorption profiles, adjusting parameters such as nanoparticle size and shape to find optimal performance strategies. Comparative figures illustrate significant absorption profile differences between solar cells with and without plasmonic enhancements. The study concludes that plasmonic nanoparticles can boost light absorption, broaden spectral coverage, and reduce material usage, enhancing the cost-effectiveness and sustainability of solar cells. The novelty statistical analyses reveal higher mean absorption, broader spectral coverage, and increased absorption efficiency across wavelengths for plasmonic-enhanced profiles. The absorption range (300–1400 nm) captures critical parts of the solar spectrum, optimizing energy harvesting across both visible and near-infrared ranges. Enhanced absorption leads to better performance under varied lighting conditions, demonstrating the effectiveness of plasmonic structures. Increasing the plasmonic enhancement factor further boosts absorption and broadens the spectrum, showing potential for optimizing materials and structures in solar cells. Future research is directed toward experimental validation and expanding the modeling to other materials and configurations. Results indicate notable increases in absorption factors for plasmonic-enhanced cells, particularly at peak wavelengths of 600 nm and 800 nm, demonstrating significant potential for improved energy harvesting across critical parts of the solar spectrum.
