The Chinese solar module maker Risen has revealed that its Hyper-ion Pro-Zonne module, based on its own N-type HJT technology, has achieved an average capacity of 740 W in mass production.
According to the Fujian Metrology Institute, the cell efficiency of the module is 26.61%, with incoming losses limits limited to 1.8%, resulting in a module efficiency of 24.81%.
The company attributed the performance to various internal technologies, including a stress-free cell interconnection method, a zero-bus bar design and the use of ultra-thin silicon waffles.
Other important developments include a reduction in silver use up to 5 mg/W-accident 37.5% lower than regular tunnel oxide-passivated contact (Topcon) modules-combined with screen prints to lower non-silicon costs. Encapsulation losses are reported at 1.8%, with fracture rates during production under 0.03%.
The company said that the performance tests by SGS in Saudi Arabia demonstrated that the Hyper-ion Pro module achieved a profit of power generation of 4.09% compared to Topcon products, with an average profit of 6.04% registered in August. The temperature coefficient is reported at -0.24%/C and the bifaciality of the module at 90%. Based on these figures, the company estimates an annual increase in the 3 GWH electricity generation for a 100 MW factory.
Risen also stated that the carbon footprint of the product was measured with 376.5 kg CO₂ equivalent per kW.
According to the company, the 740 W Hyper-ion Pro module is implemented in regional projects for regional projects in the field of utility scale, distributed commercial and high temperature. In China, HJT-Specific tenders have exceeded more than 9 GW for 2025, with the participation of state owners, including China Green Development Group (CGDG) and China National Nuclear Corp. (CNNC).
Yang Bochuan, director of Risen’s Global PV Research Institute, said that the company focuses on cell efficiency above 27% and crystalline silicon module outputs above 790 W within three years. It is also planning to speed up the commercialization of tandem cell technology, aimed at mass production of modules of more than 850 W in 2028.
From June 2025 Risen reports 15 GW of the production capacity of HJT module and 6 GW HJT cell capacity. Another 10 GW celf facility is under construction in the Chinese province of Anhui and is planned for completion by the end of the year.
