Photovoltaic performances enhanced by novel indium nanoparticles using surface plasmonic in GaAs-based 3-junction solar cells
Photovoltaic Specialists Conference（2012）
Abstract
We report the performance enhancement of GaAs-based triple-junction solar cells using novel indium nanoparticles upon the cell front-surface to achieve the top cell current matching. The external quantum efficiency (EQE) enhancements of >; 5% in top cell at wavelengths from 350 nm to 450 nm are achieved as the cell with indium nanoparticles plasmonic structure. Besides increasing in short circuit current (ISC) of 11.20% (from 2.95 mA to 3.28 mA) and in conversion efficiency (η) of 13.5%(from 20.8% to 23.6%) are also obtained under one sun AM1.5G illumination.
