Development of low-cost thin film polycrystalline silicon solar cells for terrestrial applications. Annual progress report, 1 Jan--31 Dec 1974

Technical Report ·
OSTI ID:7192013
Polycrystalline silicon solar cell structures were deposited on borosilicate/steel, graphite, and metallurgical-grade silicon substrates by the thermal decomposition of silane and the thermal reduction of trichlorosilane containing appropriate dopants. Solar cells on borosilicate/steel substrates showed very low conversion efficiencies. Solar cells on graphite substrates of 6 sq cm area had AMO efficiencies of up to 2%, and a substantial improvement in efficiency is believed to be attainable by improving the chemical and structural properties of silicon. Solar cells on metallurgical silicon substrates with AMO efficiencies of up to 2.6% were obtained, and the optimization of the device structure will lead to further improvement of conversion efficiency.
