Light-Trapped, Interconnected, Silicon-Film (TM) Modules: Annual Subcontract Report, 18 November 1994 - 18 November 1995

This report describes the first year of work performed by AstroPower, Inc., of Newark, Delaware, under the Thin-Film PV Partnership Program. The work led to the development of a new barrier-coated substrate that has enabled high-quality thin-layer polycrystalline silicon to be grown on a low-cost substrate. High diffusion lengths were measured after external phosphorous gettering. This led to aconfirmed 12.2% efficiency for a 0.57cm2, thin-layer solar cell grown on a low-cost substrate. ;
