Abstract
High‐efficiency p‐Ga1−xAlxAs, p‐GaAs, n‐GaAs solar cells are made by isothermally soaking n‐GaAs substrates in an undersaturated Zn‐doped Ga‐Al‐As melt. This one‐step growth procedure produces a graded band gap p‐Ga1−xAlxAs layer 0.2–0.4 μm thick. Efficiencies of 18.5% AM0 and 21.9% AM1 have been measured.Keywords
