Abstract
This paper presents a cost-effective and scalable fabrication process for high-quality selective double-side tunnel oxide passivating contact (DS-TOPCon) solar cells, featuring a front SiOx/Poly -Si selective emitter. A novel two-tier co-diffusion process simultaneously forms phosphorus-and boron-doped poly-Si layers on both sides in a single step, eliminating the need for additional masking and diffusion processes. The full-area DS-TOPCon cell precursors, fabricated through this rapid process, demonstrated the best iVoc of 738 mV and iFF of 86.3%. An inkj et-based patterning technique for the full-area front poly-Si, coupled with n-Si field re-passivation process, retains the passivation quality, and successfully transforms it into selective DS-TOPCon cell precursor. Initial device fabrication on large area Czochralski (Cz) n-Si wafers achieved 22.0% cell efficiency with 714 mV open-circuit voltage Voc ) after post-metallization treatments (laser enhanced contact optimization and light/heat treatment). These results suggest that with further process optimizations and improvements in material and contact properties, the efficiency of selective DS-TOPCon solar cells has potential to surpass 25%, making it a promising alternative to fabricate high-efficiency next-generation solar cells at low-cost.
