Abstract:A low-cost, high-yield technology for producing single-crystal silicon solar cells at high volumes, and suitable for export to developing countries, is described. Thc proccss begins with 100 mm diamctcr as-sawn single-crystal p-type wafers with one primary flat. Processing steps include ctching and surfacc texturization, gaseous-source diffusion, plasma etching, and contacting via screen printing. Thc necessary adaptations of such standard processes as diffusion and plasma ctching to solarcell production are d… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
