en.Wedoany.com Reported - Dimension News, June 3-5 – China National Nuclear Corporation's subsidiary, CNNC Photovoltaic, presented its full lineup of commercial-grade perovskite solar products at the 19th (2026) International Solar Photovoltaic and Smart Energy (Shanghai) Conference & Exhibition, highlighting comprehensive application solutions covering ground-mounted power stations, distributed photovoltaics, BIPV, vehicle-mounted systems, and consumer electronics.
Commercial-Grade Rigid Single-Junction Modules: Breakthroughs in Efficiency and Stability
The 1200×1600mm² rigid perovskite modules demonstrate outstanding overall performance. Without ALD/RPD processes: In terms of efficiency, certified by the China Institute of Metrology under MPPT steady-state testing mode (Note: MPPT is more stringent, simulating actual outdoor power generation conditions), mass production efficiency ranges from 19.10% to 19.57%, with champion full-area efficiency exceeding 21%. For stability, the modules passed the full suite of TÜV SÜD IEC 61215/IEC 61730 stability tests in one go. Featuring a dual-glass structure and anti-potential-induced degradation materials, the products offer low degradation and strong environmental adaptability, effectively mitigating risks of microcracks and hot spots.
Perovskite-Silicon Tandem Modules: Continuous Advancement in Technology Reserves
CNNC Photovoltaic's independently developed four-terminal perovskite-silicon tandem modules achieve an output power exceeding 500W. Combining the advantages of perovskite and silicon technologies through bandgap tuning and optical optimization, these modules deliver high power output, effectively reducing BOS costs for power stations and increasing energy yield per unit area, making them widely applicable to ground-mounted and distributed photovoltaic scenarios.
Colored Semi-Transparent and Flexible Modules: Adaptable to Diverse Scenarios
Concurrently exhibited differentiated products include: BIPV colored power-generating curtain walls with customizable transmittance ranging from 20% to 60%, balancing building daylighting, aesthetics, and power generation. Lightweight flexible perovskite modules, as thin as 2.7mm with a minimum bending radius of just 5mm, support personalized customization and can be applied to curved roofs, vehicle-mounted photovoltaics, outdoor equipment, and consumer electronics power supply.
During the exhibition, TÜV SÜD awarded CNNC Photovoltaic the IEC 61215/61730 full-sequence certification for its 1200×1600mm² commercial-grade large-size perovskite modules. This certification is a core passport for solar modules entering global mainstream markets, covering product performance reliability and electrical safety assurance. Additionally, CSA Group granted CNNC Photovoltaic the UL 61730 certification, a key准入 standard for the North American photovoltaic market, encompassing critical requirements from the American Electrical Association on module electrical safety and fire performance. With these two international high-standard certifications, CNNC Photovoltaic accelerates its products' global market entry and large-scale overseas delivery.
Looking ahead, CNNC Photovoltaic will continue to deepen perovskite technology iteration and industrialization, accelerate the large-scale global deployment of its products, contribute to the high-quality development of the photovoltaic industry, and play a core role in the green transformation of the energy structure.
