GCL Optoelectronics, a subsidiary of GCL Group, has secured a 1.2 MW commercial perovskite tandem module procurement project launched by Huaneng Clean Energy Research Institute, according to a tender document published on March 18 on the e-commerce platform of China Huaneng Group.
The company was named the sole winning bidder for the project, which calls for commercial-grade perovskite/silicon heterojunction (HJT) tandem photovoltaic modules. These modules will be deployed in an outdoor demonstration power plant to be developed by Huaneng.
The tender sets out stringent technical and commercial requirements. Modules must achieve a mass-production conversion efficiency of at least 26%, obtain full IEC 61215 and IEC 61730 certification, and be supplied from a production line with a minimum capacity of 100 MW.
In addition, the modules must demonstrate long-term durability, with outdoor degradation performance aligned with a 25-year operational lifespan. Delivery is scheduled for completion by the end of June 2026, alongside a 25-year performance warranty.
Notably, the procurement marks a shift in industry expectations. Unlike earlier projects that focused on laboratory samples or pilot-scale products, this tender explicitly requires fully commercial, mass-producible tandem modules with international certification and large-scale supply capability.
According to Huaneng, this represents the first publicly tendered commercial perovskite tandem module procurement among China’s five major state-owned power generation groups.
GCL Optoelectronics states that it has achieved mass production of perovskite modules at its manufacturing facility in Kunshan, positioning it among the early movers in the commercialization of perovskite technology in China.
The company reports that its products have passed IEC 61215 and IEC 61730 certification standards and have completed over 10,000 hours of reliability testing, including damp heat, ultraviolet exposure, and thermal cycling.
GCL Optoelectronics also highlights a growing intellectual property portfolio, with more than 500 patent applications covering perovskite tandem materials, manufacturing processes, and device structures.
The project underscores growing momentum toward the commercialization of perovskite/silicon tandem solar technology. By combining high efficiency with scalable manufacturing, tandem modules are increasingly seen as a key pathway to surpass the performance limits of conventional silicon photovoltaics.
As large state-owned energy groups begin to procure commercial-scale systems, the industry may be entering a new phase—moving from laboratory validation to real-world deployment.
