Sake fasalin TOPCon zuwa BC: Abin da ke Canzawa, Abin da Yake Kashe kowane GW
Teburin Abubuwan Ciki
Amsa mai sauri: A TOPCon module line can be converted to back-contact assembly without touching lamination, framing or edge sealing — 85–90 % of the back end stays. What changes is stringing: cells run back-side up, so the SMBB welder gives way to a 0BB platform with two-channel UV dispensing, low-stress cleaving, rear vision and a de-gluing rework station, while a dispense kit bolted onto the old welder only produces samples. The UV-adhesive route costs about RMB 30–40 million per GW (US$4.2–5.6 million at 7.1), the IFC film route RMB 45 million and up, and a reported 7 GW project worked out at about RMB 33.5 million per GW. The binding constraint is not the purchase order: it is a 2–4 month yield ramp with breakage running one to two points above the TOPCon baseline.
