Systems and methods for enhanced light trapping in solar cells

摘要

Methods for improving the light trapping characteristics of crystalline silicon solar cells are provided. In one embodiment, the backside surface of a crystalline silicon solar cell substrate is textured with a pulsed laser beam. The textured backside surface of the back contact solar cell crystalline silicon substrate is then annealed to remove damage from the laser texturization process. Backside metallization is then formed on backside base and emitter regions.
