Jolywood claims to have achieved an influence conversion effectivity of 26.7% for an n-type M10 photo voltaic cell primarily based on TOPCon know-how.
The China Academy of Metrology and Science confirmed the outcome, which Jolywood mentioned now represents a world report for an n-type TOPCon cell. That is an enchancment on the corporate’s earlier report of 26.1%, which was achieved in November 2022.
The Chinese language photo voltaic module maker mentioned it achieved the brand new outcomes because of its independently developed Plasma Oxidation & Plasma Assisted Insitu-doping Deposition (POPAID) know-how. POPAID reportedly overcomes points with comparable doped amorphous silicon know-how.
“Via steady technological innovation, Jolywood has efficiently developed varied applied sciences reminiscent of impurity extraction within the physique area of the silicon wafer, a neighborhood polysilicon layer, regulation of the hydrogen content material of the polysilicon movie, new metallic harm restore, and ultra-fine gate line printing,” the corporate mentioned. “By adopting mass manufacturing gear and supplies within the manufacturing line, Jolywood has achieved a conversion effectivity of 26.7%, which factors to a transparent technical route for the long run enchancment of the mass manufacturing effectivity of the TOPCon cell.”
Jolywood lately commissioned a 1.5GW TOPCon photo voltaic cell manufacturing unit in Taizhou, in China’s Zhejiang province.
“With this new manufacturing facility, our TOPCon photo voltaic cell manufacturing capability has reached 3.6GW,” an organization spokesperson mentioned. pv journal.
In October, the corporate introduced a bifacial 700W TOPCon photo voltaic module at Intersolar in Munich, Germany. In January, it unveiled a 615W TOPCon product.
