GCL Perovskite, the perovskite subsidiary of GCL Group, has announced that its commercial perovskite PV module developed in-house has successfully passed triple-strength accelerated aging tests based on international standards IEC 61215:2021 and IEC 61730:2023. According to the company, it is the world’s first perovskite module to pass such stringent certification. The tests, conducted by TÜV Rheinland, extended the duration or cycle counts of critical aging procedures, such as damp heat and thermal cycling, to 3 times the standard requirements. The company said that its perovskite module showed ‘excellent reliability and performance’ throughout the rigorous evaluation that simulated long-term module degradation under extreme conditions.
Last month, GCL Perovskite launched the ‘world's first’ perovskite AI high-throughput device (see China Solar PV News Snippets).
Perovskite manufacturer SolaEon has announced that it has set a new world record by achieving a certified power conversion efficiency of 20.7% on a full-area (0.72 m²) single-junction perovskite module (1.2 × 0.6 m), as verified by China National Institute of Metrology. The company says it is the first time that any perovskite module has surpassed the 20% efficiency threshold at a square-meter scale, delivering an output of 149 W. SolaEon recently commissioned a 200 MW perovskite production line in March, which is now in volume production with commercial orders being delivered and a reported yield exceeding 95%.
In April, SolaEon announced that its all-perovskite tandem solar cell achieved a certified conversion efficiency of 31.38% (see China Solar PV News Snippets).
PV inverter maker Sungrow has officially unveiled its PowerTitan 3.0 smart energy storage platform, with the first full system rolling off the production line on June 5. The company says PowerTitan 3.0 is the industry’s first large-scale deployment of silicon carbide (SiC)-based power conversion systems (PCS) and features its proprietary thermal-electric separation technology, enabling a system round-trip efficiency (RTE) of 93.5%.
Sungrow also introduced its third-generation high-capacity battery cells, offering 3 product variants under PowerTitan 3.0: Flex, Class, and Plus. The Plus version features a single cabinet energy capacity of 12.5 MWh and an energy density exceeding 500 kWh/m2, both of which, the company claims, rank among the highest globally. It adds that this enables significant reductions in land use and cabling costs, effectively lowering CapEx.
Sungrow unveiled its latest C&I Energy Storage System, PowerStack 255CS, at the recently held Intersolar Europe 2025 (see Sungrow’s Latest C&I Scale ESS Solutions For Europe).
Vertically integrated solar PV manufacturer Trinasolar has won the Silver Award at the 25th China Patent Awards. The company says it is the first PV tracker company to receive this national-level intellectual property honor. The award-winning patent (ZL202010441260.8), titled ‘Method for Estimating Direct Irradiance Ratio Using Dual Pyranometers,’ was jointly recognized by China’s National Intellectual Property Administration (CNIPA) and the World Intellectual Property Organization (WIPO). The innovation introduces a sunshine index prediction algorithm and a dual pyranometer-based measurement system, enabling accurate, real-time weather condition classification and dynamic tracker angle adjustment. This breakthrough allows PV modules to consistently operate at optimal generation angles while overcoming technical barriers previously controlled by overseas patents.
