Abstract

Solar cells with measured sea level sunlight power conversion efficiencies of 13–18% and areas of several cm2 have been prepared by vapor phase epitaxial growth of n-AlAs on p-GaAs substrates. The cells are provided with an antireflective passivating anodically grown coating and have much improved stability in the laboratory atmosphere.
