Abstract

Abstract We investigated the properties of nitride‐based solar cells under concentrated light illumination from 1 to 200 suns. The conversion efficiency of our solar cells increased with increasing concentration up to 200 suns. The short‐circuit cur‐ rent density, open‐circuit voltage, fill factor, and conversion efficiency were 510 mA/cm 2 , 1.9 V, 70%, and 3.4%, respectively, under an air mass filter of 1.5G at 200 suns and room temperature.
