Abstract
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 crystalline silicon solar cell substrate is then annealed to remove damage from the laser texturization process.
