摘要
This paper reports on efforts to improve the photovoltaic performance of crystalline silicon solar cells by combining the plasmonic scattering of silver nanoparticles (Ag NPs) with the luminescent downshifting (LDS) effects of Eu-doped phosphors. The surface morphology was examined using a scanning electron microscope in conjunction with ImageJ software. Raman scattering and absorbance measurements were used to examine the surface plasmon resonance of Ag NPs of various dimensions in various dielectric environments. The fluorescence emission of the Eu-doped phosphors was characterized via photoluminescence measurements at room temperature. We examined the combination of plasmonic and LDS effects by measuring the optical reflectance and external quantum efficiency. Improvements in the photovoltaic performance of the solar cells were determined by photovoltaic current density-voltage under AM 1.5G illumination. A combination of plasmonic and LDS effects led to an impressive 26.17% improvement in efficiency, whereas plasmonic effects resulted in a 22.63% improvement compared to the cell with a SiO2 ARC of 17.33%.
