- Abstract
We demonstrate mask-free fabrication of a 22.0%-efficient crystalline Si solar cell by applying laser ablation of Si and by laser ablation of protective coatings. The bulk absorber material is a p-type float zone silicon wafer and the designated cell area is 4 cm2. While the processing time of our laboratory-type of laser system is far too slow for industrial processing, we estimate on the basis of our experiments that laser processing of 12.5 × 12.5 cm2-sized solar cells in just a few seconds is feasible with commercially available equipment.
