As global photovoltaic (PV) installations continue to soar, the long-term reliability of PV modules under extreme climates has become a focal point of the industry. Recently, "HIUV New Materials," a leading domestic PV material enterprise, announced that its newly developed "space-grade" organosilicone encapsulant film has successfully passed rigorous radiation resistance tests and is about to enter mass production. The core of this revolutionary encapsulant lies in the cross-linking reaction between a special phenyl-containing linear silicone oil and a bulky silicone resin, constructing an extremely stable polymer network. Thanks to the introduction of phenyl raw gum (the precursor to phenyl silicone resin), the film not only maintains stable performance across an ultra-wide temperature range of -196°C to 400°C, but its UV radiation resistance is also more than 10 times that of ordinary EVA films, making it perfectly suited for extreme environments like deserts, plateaus, and outer space. Furthermore, to boost the power generation efficiency of the modules, the R&D team laminated an ultra-slip self-cleaning coating on the film's surface. Leveraging the low surface energy properties of modified fluorosilicone oil, this coating gives the PV panels excellent hydrophobic and oleophobic capabilities, effectively reducing dust accumulation and keeping the modules in a "self-cleaning" state outdoors. It is estimated to increase the lifetime power generation gain of power stations by over 1.5%. Industry experts point out that with the cross-boundary application of high-performance materials like solid phenyl silicone rubber in the photovoltaic field, the "longevity" and "high efficiency" of domestic PV modules will be doubly guaranteed, further solidifying China's leading position in the global new energy industry chain.
