Recent development in laser technology and optical instruments enables new processes and technologies in the energy industry. Laser processing provides several advantages over the conventional processes includes precision of operation, local treatment, fast processing, and low cost. Shaping the energy materials is one of the major applications in laser processing, includes net shaping of thermoelectric pins, scribing of thin-film solar cells, edge isolation of crystalline silicon solar cells, laser doping of solar cells, surface texturing for hydrophobicity, and photon capturing.
