New low-temperature protection material for photovoltaic systems: Bafang silicate anti-icing coating

Scientists from Poland have developed a new type of anti-icing coating for photovoltaic panels, which is based on transparent silicone epoxy resin and modified with two or three kinds of functionalized organic silicides with customizable structure-octahedral silicate (OSS) to enhance the anti-icing performance.

Researchers created five different coating samples to investigate their icephobic properties by measuring the adhesion force (IA) of ice and the freezing delay time (FDT) of water droplets. They found that compared to unmodified samples, samples modified with bifunctional and trifunctional octasilicate esters for silicone epoxy coatings showed a decrease in IA and a significant extension in FDT. It can be seen that modification can indeed improve anti icing performance.

The formation and accumulation of ice and snow on photovoltaic panels will obstruct light, thus reducing its power generation efficiency. However, at present, the method of removing snow/ice from the device is still manual cleaning or using chemicals, which may lead to environmental pollution and damage the surface of photovoltaic modules.

As a promising solution, the modified coating not only does not affect the optical properties of the coating, but also has strong anti-icing performance. Therefore, the coating may replace the inefficient deicing method used in industry and be applied to photovoltaic panels.
