Standard Cell Processing: PERC, PERL and PERT
This lecture covers the standard cell processing techniques for silicon solar cells, focusing on PERC, PERL, and PERT structures. Topics include surface texturing, p-n junction diffusion, antireflection coating, screen-printing, firing processes, and the history of c-Si photovoltaics. The instructor discusses the evolution from Al-BSF to PERC cells, the analysis of high-efficiency cells, and the challenges and advancements in solar cell manufacturing. The lecture also explores the importance of cost control, process stability, efficiency, and scalability in industrial manufacturing requirements for solar cells.
