Jolywood claims to have achieved an influence conversion effectivity of 26.7% for an n-type M10 photo voltaic cell primarily based on TOPCon expertise.
The China Academy of Metrology and Science confirmed the end result, which Jolywood stated now represents a world file for an n-type TOPCon cell. That is an enchancment on the corporate’s earlier file of 26.1%, which was achieved in November 2022.
The Chinese language photo voltaic module maker stated it achieved the brand new outcomes due to its independently developed Plasma Oxidation & Plasma Assisted Insitu-doping Deposition (POPAID) expertise. POPAID reportedly overcomes points with related doped amorphous silicon expertise.
“By way of steady technological innovation, Jolywood has efficiently developed varied applied sciences comparable to 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 injury restore, and ultra-fine gate line printing,” the corporate stated. “By adopting mass manufacturing tools and supplies within the manufacturing line, Jolywood has achieved a conversion effectivity of 26.7%, which factors to a transparent technical route for the longer term enchancment of the mass manufacturing effectivity of the TOPCon cell.”
Jolywood just 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 stated. 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.
