Chinese solar manufacturer Huasun has finalized a significant deal to provide 1.2 gigawatts (GW) of G12R (210mm) rectangular heterojunction (HJT) solar cells to an undisclosed company. The collaboration agreement outlines that Huasun will be the exclusive supplier of these solar cells, with both entities set to engage in joint efforts, including research and development initiatives focused on advancing HJT technology. This marks the first-ever gigawatt-scale deal specifically for rectangular HJT cells, as confirmed by the company.
The Everest G12R rectangular HJT solar cells are constructed on a half-cell silicon wafer measuring 182mm*105mm, incorporating HJT3.0 bifacial microcrystalline mass production technology, advanced silver-coated copper, and super multi-busbar (SMBB) processes. This integration aims to enhance photoelectric conversion efficiency, reaching an impressive 35.5% for mass-produced cells.
Huasun's strategic focus on HJT technology in both cells and modules has proven successful, with the company shipping over 3GW of products in 2023, as reported by Yang Zongyuan, the general manager of Huasun's sales division in China.
Additionally, the company has demonstrated continuous improvements in module efficiency. Notably, the Huasun Himalaya G12-132 HJT solar module achieved a noteworthy power output of 750.544W and an impressive conversion efficiency of 24.16%. This certification was granted by TÜV SÜD, a solar testing and certification institute headquartered in Munich, in November of the previous year.
