Abstract
Thin films have been produced over a wide range of values by concurrent vacuum evaporation of the constituent elements. The most consistent results in terms of producing single‐phase material were obtained when substrate temperatures were in the range of 350°–450°C. Photoelectrochemical evaluation of the resultant thin films indicated postdeposition heat‐treatment and surface etching were necessary to maximize photovoltaic outputs. A dependence of photoelectrochemical behavior, bandgap, and efficiency on value was also found. The maximum efficiency recorded was 7.4% for a composition under simulated AM2 conditions.Keywords
