Risen Energy’s Steel Frame HJT Module In Mass Production

• Risen Energy has started mass production of its 210 mm n-type HJT solar module with a steel frame
• The steel frame is aimed at reducing the module's tear-resistance by over 20% and also helps bring down its CO2 footprint
• The new module offers a maximum efficiency of over 22.5% and power output of 710 W, according to Risen

Chinese solar PV company Risen Energy has put its 210 mm n-type heterojunction (HJT) solar modules packed in a steel frame into mass production claiming its maximum power output as reaching 710 W and efficiency exceeding 22.5%.

The module offers a stable temperature coefficient and 85%±5% ultra-high bifaciality. It uses 100 μm ultra-thin cell technology and a low-temperature process, which can lower the the module's carbon footprint to less than 400kg eq CO2/ kWc, according to Risen.

Instead of the traditional metal frame, Risen says the use of a high-strength alloy steel frame for the module strengthens its tear-resistance by over 20% and can greatly reduce its CO2 emissions. As recycled steel gains popularity in China, the low-carbon advantages will further be available for Risen to exploit, it added.

The Chinese company has a 500 MW cell and module production capacity each for its HJT Hyper-ion products. It targets to expand the same to 5 GW each by H1/2023 and to 15 GW each by 2023-end, as shared by the company's General Manager, HJT, BU, Po-Chuan Yang during TaiyangNews High Efficiency Solar Technologies Conference in November 2022 (see Day 2: TaiyangNews High Efficiency Solar Technologies Conference).
