Highhyphen;performance solar cell material:nhyphen;AlAs/phyphen;GaAs prepared by vapor phase epitaxy

摘要

Solar cells with measured sea level sunlight power conversion efficiencies of 13ndash;18percnt; and areas of several cm2have been prepared by vapor phase epitaxial growth ofnhyphen;AlAs onphyphen;GaAs substrates. The cells are provided with an antireflective passivating anodically grown coating and have much improved stability in the laboratory atmosphere.
