Production capacity could exceed 50 GW in 2022Debates have been heated on which of TOPCon and HJT can succeed PERC to be the next-gen mainstream cell technology. With Jinko, Jolywood, Jietai, and Runergy announcing large-scale capacity expansion plans, TOPCon production capacity is expected to exceed 50 GW in 2022. Production capacity additions per year will increase by nearly 80 GW in 2030. In the short run, TOPCon has been in the lead.
Non-silicon costs of TOPCon cells have reduced to under RMB 0.3/W, still RMB 0.18-0.22/W higher but will gradually approach to that of PERC, Zhao said, as metallization costs decline, yield rates and efficiency improve, and, just like PERC, can be used to produce large format products.
During the conference, Zhao gave detailed introduction of current TOPCon process flows, comparing their pros and cons. The talk also dealt with the much-discussed question of whether n-type wafer supply can meet the surging demand from n-type cells, probing into the future of TOPCon technology.
