Abstract
The purpose of the overall program is to establish technological readiness and provide verification for the elements of a manufacturing sequence which would ultimately be suitable for the large-scale production of silicon solar-array modules at a selling price of less than $500/kW. A program and process plan for accomplishing this objective was developed and put into operation. This plan is centered around a processing sequence using Czochralski, silicon wafers. Three junction-formation processes are considered since cost analyses show that they do not differ greatly in cost. The progress made in the various process steps of the plan is described, and plans for the next quarter are summarized.
