Abstract
The photovoltaic performance enhancement of silicon solar cells depositing indium nanoparticles (In NPs) on TiO2 layer and capping an Al2O3 layer was demonstrated. The impressive performance enhanced was attributed to the In NPs broadband light scattering based on Al2O3/TiO2 antireflection. The optical reflectance, photovoltaic current-voltage, and external quantum efficiency were measured and compared with various thickness of TiO2 layer. The efficiency enhancement of 54.5% (from 10.96% to 16.93%) was obtained when the cell with In NPs embedded in the Al2O3 (65-nm)/TiO2 (20-nm) structure.
