Researchers at the Department of Electronic Engineering of the Universitat Politècnica de Catalunya (UPC) have obtained a record efficiency of 22% with silicon solar cells that incorporate a surface treatment called black silicon on the front of the cell. This technique coats the surface with a dry chemical that results in small conical tips at the nanometric scale.
