Abstract

InGaN/GaN multiple-quantum-well solar cells were grown on (111) Si substrates. AlN/AlGaN superlattice and self-assembly Si_xN_y masking islands were employed to alleviate the material mismatches between Si and GaN. The devices were characterized under the illumination of AM 1.5 G with different solar concentrations. As the concentration ratios increased from 1-sun to 105-sun, energy conversion efficiency was enhanced by 25%, which was noticeably greater than the enhancement reported on sapphire substrates under similar solar concentrations. The result is attributed to the superior heat sinking of Si substrates.
