Abstract :
In this paper, we report on the successful fabrication, using the MOCVD method, of a high efficiency In0.5Ga0.5P single junction solar cell on a GaAs substrate. We optimized the cell structure and the growth conditions. The minority carrier lifetime was improved using a growth temperature of 700°C and a maximum conversion efficiency of 17.4% was achieved under AM 1.5 condition
