Abstract
This study characterized the plasmonic scattering effects of indium nanoparticles (In NPs) on the front surface and silver nanoparticles (Ag NPs) on the rear surface of a thin silicon solar cell according to external quantum efficiency (EQE) and photovoltaic current–voltage. The EQE response indicates that, at wavelengths of 300 to 800 nm, the ratio of the number of photo-carriers collected to the number of incident photons shining on a thin Si solar cell was enhanced by the In NPs, and at wavelengths of 1,000 to 1,200 nm, by the Ag NPs. These results demonstrate the effectiveness of combining the broadband plasmonic scattering of two metals in enhancing the overall photovoltaic performance of a thin silicon solar cell. Short-circuit current was increased by 31.88% (from 2.98 to 3.93 mA) and conversion efficiency was increased by 32.72% (from 9.81% to 13.02%), compared to bare thin Si solar cells.

We examined the degree to which photovoltaic performance was enhanced by the plasmonic scattering of indium nanoparticles (In NPs) and Ag according to external quantum efficiency (EQE) and measurements of photovoltaic current–voltage (I-V)
Short-circuit current was increased by 31.88%, and conversion efficiency was increased by 32.72%, compared to those of bare thin Si solar cells
Summary
Photovoltaic energy is a viable renewable source of energy for coming generations. the cost per unit of electricity generated by a photovoltaic system is higher than the retail price of electricity generated using conventional methods. Current photovoltaic technology is based on bulk waferbased crystalline silicon (C-Si) technology, which depends on the cost of Si materials and processing. Many light-trapping methods have been proposed to achieve high efficiency without incurring high costs. Most previous studies have shown that silver (Ag) and gold (Au) nanoparticles (NPs) can be used in bulk wafer-based C-Si solar cells or thin-film Si solar cells where the NPs are deposited on one surface of the solar cells [1,3,4,8,9,10,11,12]. Few studies have examined the effects of metallic NPs deposited on the front and back surfaces of a thin Si solar cell [13]
