Series Resistance Associated with Thick-Film Contacts to Solar Cells

摘要

A high series resistnace is often associated with thick-film contacts on solar cells. A study of the thick-film silver/silicon interface of a single-crystal silicon solar cell is presented. Series and contact resistance measurements and scanning electron microscopy, in conjunction with hydrofluoric acid etching of cells, lead toward an understanding of the silver/silicon interface and of the barriers to current flow.
