This paper describes the spectral characteristics of GaAs solar cells grown by low-temperature liquid phase epitaxy (LPE). It demonstrates improvements in blue response and peak internal quantum efficiencies of 100% for an optimized cell structure with isovalent In doped base and ultrathin (<100{angstrom}) heavily doped cap p{sup +}-GaAs layer on the photosensitive surface. The conversion efficiency obtained from the optimized cells under one-sun AM 1.5 conditions is 23.4%. Their results indicate that the low-cost LPE-grown films are suitable for high-efficiency solar cells.
