Shunt isolation in silicon solar cells by chemical etching

Abstract

A significant percentage of crystalline silicon solar cells produced by the industry are classified as off-spec or non-prime cells as a result of electrical shunts and are rejected during post-manufacturing quality checks. Repairing these non-prime cells, so they can be used for electrical generation, can help improve the overall yield of the solar cell industry. It was found that localized shunts can be successfully isolated by chemical etching to yield fuctional solar cells in terms of thermal- and electrical properties. Keywords: Multicrystalline silicon, Shunts, Isolation
