Electrical and Optical Performance of Silicon Solar Cells Using Plasmonics Indium Nanoparticles Layer Embedded in SiO2 Antireflective Coating

In this study, we demonstrate the photovoltaic performance enhancement of silicon solar cell by means of plasmonics indium nanoparticles (In-NPs) layer embedded in SiO
₂
antireflective coating (ARC). The optical reflectance, external quantum efficiency and photovoltaic current-voltage are measured and compared. Impressive conversion efficiency enhancement of 35.94% for the cell with double In-NPs layers ARC, 34.77% for the cell with single In-NPs layer ARC and 26.67% for the cell with a pure SiO
₂
ARC were obtained which is compared to the reference cells. Besides, the gain in absolute efficiency of 1.26-1.52% for the cells with In-NPs ARC was higher than that of the cell with a pure SiO
₂
ARC, due to the contribution of plasmonics scattering of In-NPs.
