Abstract
Thin film photovoltaic solar cells are made by forming the cell structure from a number of layers including the contact layers and semiconductor layers. At least one of the semiconductor layers is a tellurium containing II-VI compound. After the structure is formed, it is heated to temperatures above 300.degree. C. and then rapidly cooled at rates greater than 10.degree. C./s. Cells comprising CdS and CdTe have increased fill factor when the fabrication process includes heating and rapid cooling.
