Light-trapped, interconnected, silicon-film (trademark) modules. Annual subcontract report, 18 November 1994--18 November 1995

摘要

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 a confirmed efficiency for a 0.57cm(sup 2), thin-layer solar cell grown on a low-cost substrate.
