Solar Module Super League member Risen Energy has started commercial production of its Hyper-ion heterojunction technology (HJT) solar modules, which boast a conversion efficiency of 23.89%.

The company produced the first of the n-type HJT modules on Friday at its Nanbin manufacturing base in the city of Ningbo, China, at an event attended by company executives and government officials. The module’s maximum power output of 741.5Wp, and its efficiency rating, are records for the company’s HJT modules, and Risen expects the modules to be particularly durable, expecting their power output to fall to just 90% after 30 years.

Risen first announced the module in February of this year, and the scale-up of production is a significant milestone for the company. It has already announced plans to increase its production capacity of the Hyper-ion modules to 15GW by the end of this year, following a US$7 billion investment into new manufacturing capacity made in January 2022.

“The official operation of the Nanbin manufacturing base not only gives Risen Energy another competitive edge but also holds pivotal importance in fuelling Ninghai’s resources for developing intelligent manufacturing,” said Wu Xuegang, president and member of the executive board of Risen.

“We will focus on ramping up the production of high-efficiency modules as we continue to strengthen the solar value chain in Nanhai to achieve greater industry synergy, helping the region establish itself as a PV and energy storage powerhouse.”

Risen’s Hyper-ion modules also use technological innovations, such as surface contact passivation, to optimise efficiency in electricity production. There has been considerable investment in new technologies in the solar sector in recent months, including LONGi’s unveiling of a solar cell with a conversion efficiency of 33.5%, but implementing meaningful change to the solar sector will rely upon implementing these innovations on a large scale.

As a result, Risen’s success production of its Hyper-ion modules, and the company’s plans to further scale up operations, could be an important proof of concept for processes such as surface contact passivation in the solar sector.

FREE WEBINAR -This special webinar will take a deep dive into the latest PV ModuleTech Bankability Ratings pyramid, capturing the relative bankability status of the top 70-80 PV module suppliers globally. In addition to revealing the latest ranking of global PV module suppliers, PV Tech’s Head of Research, Finlay Colville, will show the depth of analysis and commentary included within the report for module suppliers. A key output from the webinar will be to learn which PV module suppliers have moved up the rankings pyramid in recent years and why this growth has been achieved. Conversely, some of the companies that have fallen down the rankings will be discussed, in particular those suffering from market-share losses and financial problems.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 8-9 October 2024 is our second PV CellTech conference dedicated to the U.S. manufacturing sector. The event in 2023 was a sell out success and 2024 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
