摘要： A cadmium sulfide photovoltaic cell of improved efficiency comprising a barrier layer and cadmium sulfide-containing bilayer, the bilayer being formed by depositing at a first temperature an initial layer of cadmium sulfide in interfacial contact with the substrate and then depositing a subsequent layer of cadmium sulfide at a second temperature which is at least 20.degree. C. below the first temperature.
