Processing steps used in fabricating silicon Schottky solar cells have been evaluated to optimize energy conversion efficiency. Factors such as wafer resistivity and orientation, etching, oxide growth, heat treatment, deposition technique, and grid design are included in the study. The proper heat treatment and metal deposition rate are most crucial in achieving a high open-circuit voltage. The process has produced a solar cell with V//o//c equals 0. 55 V, fill factor of 0. 71, and 8. 6% AM1 efficiency with a potential improvement to 12. 5%.
