Risen Energy officially produced the first batch of its RisenFlex Nova pHJT solar cells on August 29, 2026. This initial manufacturing milestone utilizes p-type heterojunction technology to enable thin-film applications.
Why it matters
The development marks the transition of 70μm p-type heterojunction technology from research into small-batch production. Risen Energy intends to use this specialized cell design to serve environmental applications requiring thin, flexible power sources.
The cells achieve a 21% efficiency at Beginning of Life, scaling to a maximum of 22.2% under the AM0 space standard spectrum. These dimensions are adjustable, ranging from 30×40 mm to 210×105 mm.
The players
Risen Energy
A global solar manufacturer specializing in photovoltaic module production, heterojunction research, and large-scale utility power solutions.
The details
The RisenFlex Nova series employs p-type heterojunction (HJT) technology, a method that sandwiches crystalline silicon between ultra-thin layers of amorphous silicon to minimize energy loss at the cell surface. By reducing the wafer to a thickness of 70μm—a hair-thin profile—the design achieves the flexibility required for specialized environments. This manufacturing process represents a shift toward higher-efficiency, thin-film integration that deviates from standard rigid solar module architectures.
Timeline
June 2026: Risen Energy launched the RisenFlex Nova product line.
August 29, 2026: The company produced the first batch of pHJT cells.
2027: The firm expects to establish GW-scale mass production capacity.
The Tech Race
Risen Energy is accelerating its move toward high-efficiency HJT architectures to compete with current market-leading PERC and TOPCon cell technologies. The path to GW-scale production by 2027 places the firm in direct competition with major manufacturers currently scaling their own heterojunction roadmaps.
The RisenFlex Nova series is designed for specialized environmental applications rather than standard residential rooftop use. Commercial and industrial sectors needing high-efficiency, flexible, or lightweight photovoltaic components will likely gain access to these cells as the company scales to mass production.
The takeaway
Risen Energy has moved p-type heterojunction technology into its first production batch, pushing the limits of cell thinness and efficiency. Stakeholders should monitor the company’s progress toward its 2027 goal of achieving GW-scale manufacturing.
What happens next
Risen Energy plans to scale the production of these cells to a GW-capacity facility by 2027. Future milestones will include the development of cells with a thickness of less than 70μm.
