Monolithic Amorphous Silicon Modules on Continuous Polymer Substrate, Final Subcontract Report, 9 January 1991 - 14 April 1991

    Research output: NRELSubcontract Report

    Abstract

    This report examines manufacturing monolithic amorphous silicon modules on a continuous polymer substrate. Module production costs can be reduced by increasing module performance, expanding production, and improving and modifying production processes. Material costs can be reduced by developing processes that use a 1-mil polyimide substrate and multilayers of low-cost material for the frontencapsulant. Research to speed up a-Si and ZnO deposition rates is needed to improve throughputs. To keep throughput rates compatible with depositions, multibeam fiber optic delivery systems for laser scribing can be used. However, mechanical scribing systems promise even higher throughputs. Tandem cells and production experience can increase device efficiency and stability. Two alternativemanufacturing processes are described: (1) wet etching and sheet handling and (2) wet etching and roll-to-roll fabrication.
