Improved cell photovoltaic conversion efficiencies are obtained by the simultaneous elemental reactive evaporation process of Mickelsen and Chen for making semiconductors by closer control of the evaporation rates and substrate temperature during formation of the near contact, bulk, and near junction regions of a graded I-III-VI[sub 2], thin film, semiconductor, such as CuInSe[sub 2]/(Zn,Cd)S or another I-III-VI[sub 2]/II-VI heterojunction. 1 fig.
