New Metallization Technique Suitable for 6-MW Pilot Production of Efficient Multicrystalline Solar Cells Using Upgraded Metallurgical Silicon: Final Technical Progress Report, December 17, 2007 -- June 16, 2009

Research output: NRELSubcontract Report

Abstract

This report describes CaliSolar's work as a Photovoltaic Technology Incubator awardee within the U.S. Department of Energy's Solar Energy Technologies Program. The term of this subcontract with the National Renewable Energy Laboratory was two years. During this time, CaliSolar evolved from a handful of employees to over 100 scientists, engineers, technicians, and operators. On the technical side,the company transitioned from a proof-of-concept through pilot-scale to large-scale industrial production. A fully automated 60-megawatt manufacturing line was commissioned in Sunnyvale, California. The facility converts upgraded metallurgical-grade silicon feedstock to ingots, wafers, and high-efficiency multicrystalline solar cells.
