Improvement and optimization of five laser processes to facilitate their integration into industrial PV manufacturing: 1. High throughput laser junction isolation, 2. High speed laser micro drilling for new cell concepts, 3. Damage-less laser ablation of dielectric coatings on solar cell emitters for contact formation, 4. Laser micro soldering for module interconnection, 5. Laser-selective emitter doping.
Development of prototype lasers individually optimized for these processes.
Development of a high speed laser scanning system for very high ablation and welding rates to meet an industrial throughput of 2000 wafers/hour.
Integration of the main new laser components and processes into PV manufacturing systems.
