Chinese solar manufacturer Huasun has claimed to set a new benchmark in power output for heterojunction (HJT) photovoltaic modules by achieving a power output of 750.544W and demonstrating a conversion efficiency of 24.16%.

Within a span of six weeks following its earlier accomplishment in late September, the Huasun Himalaya G12-132 HJT solar module received certification from Germany headquartered TÜV SÜD, a third-party testing and certification institution.

The Himalaya G12-132 module is constructed using double-sided microcrystalline G12-20BB HJT solar cells produced at Huasun’s Xuancheng Phase IV HJT Cell Project.

According to the head of the company’s research and development center, the average mass-production efficiency of these cells has reached 25.8%, indicating a substantial increase of 0.5% from three months ago when production commenced at the project.

The company credited this accomplishment to significant advancements in cell efficiency, coupled with the refinement of the polyisobutylene (PIB) plus light conversion film encapsulation process.

Consequently, the Himalaya G12-132 HJT module has exceeded its own record established six weeks ago, achieving a 6W increase over the previous 744.43W record.

In China, HJT, after being dropped by multiple manufacturers as an unviable technology, accounted for only 10.23% of the total expansion.

Mercom recently reported on how solar manufacturers in China have scaled up capacity as the price of polysilicon materials dropped by almost 50% during the first half of 2023.

In India, Reliance Industries formalized a letter of commitment with Maxwell Technology, a wholly-owned subsidiary of Suzhou Maiwei Technology, for the acquisition of eight sets of high-efficiency production lines designed for HJT cells.

Each production line has a capacity of 600 MW, collectively enabling the manufacture of an annual capacity of 4.8 GW of HJT cells.
