China’s Mellow Energy, a spin-off from Jinan University’s Institute of New Energy Technology, has unveiled what it claims to be the world’s largest flexible perovskite solar module, the ML-Flex.
Key Specifications:
- Dimensions: 1,200 mm x 1,600 mm x 1 mm
- Weight: 2.04 kg
- Efficiency: 13.5% to 15.1%
- Power Output: 260 W to 300 W
- Temperature Range: -40°C to 85°C
- Features: IP68-rated junction box
The module highlights the scalability of perovskite technology, known for its lightweight design, high efficiency, and cost-effective production. “This innovation paves the way for diverse applications, including wearable devices, portable solar products, electric vehicles, drones, and building-integrated photovoltaics (BIPV),” said CTO Shaohang Wu.
Mellow Energy’s production line has a capacity of 100 MW and supports both rigid and flexible modules. The company is in the ramp-up phase, focusing on improving performance and scalability. Third-party efficiency certifications are underway, and the company anticipates IEC 61215 certification for rigid modules by mid-year.
Technical Innovations: Last year, the team developed a monolithic perovskite solar module with improved efficiency and stability. This was achieved by preventing ion migration in the interconnect regions through an innovative ion barrier layer technique. This process enhances both the efficiency and the longevity of the modules.
The ML-Flex module’s development underscores the rapid advancements in perovskite technology, offering immense potential for wide-scale commercialization and diverse applications in the solar industry.
