en.Wedoany.com Reported - China's GCL Group has commissioned the world's first gigawatt-scale perovskite photovoltaic module factory in Kunshan, Jiangsu Province, marking the entry of third-generation solar cell technology into the stage of industrialized mass production. The factory has a planned production capacity of 2 gigawatts, with a total investment of approximately 5 billion yuan (nearly 700 million euros), aiming to reduce dependence on traditional silicon materials.
According to statistics from energy research institute Ember, silicon materials currently account for 80% of China's photovoltaic exports. GCL has achieved significant cost compression through vertically integrated production, with its perovskite module target unit price set at 0.075 euros per watt, roughly half the cost of existing technology. The factory is currently capable of producing 300 cells per day. In terms of efficiency, the conversion efficiency of single-junction perovskite modules reaches 19.04%, while silicon-based perovskite tandem modules achieve an efficiency of 29.51%. This data, certified by the National Institute of Metrology of China, surpasses the previous record of 25.2% held by Spain's IMDEA Nanoscience Institute.
The crystal structure of perovskite materials is susceptible to degradation from heat and moisture, making stability a key challenge for commercialization. To address this issue, research published in the German journal *Advanced Materials* shows that a team led by Professor Nazario Martín in Madrid used PTZ-Fl molecules to inhibit material degradation. The Chinese industry is currently testing module durability using the extreme ultraviolet radiation environment of the Kubuqi Desert. In terms of manufacturing processes, the application of granular silicon reduces energy consumption by 70% and carbon emissions by 42%, helping to obtain the low-carbon certifications required by the EU market, and enables full-process environmental traceability through blockchain technology.
