近年来，德达特化集团持续关注高分子材料在光伏领域的应用和发展趋势，不断努力为客户提供解决光伏材料耐候性问题的优化方案。为此，我司推出了多款高透光率低色度UV吸收剂，与光伏材料相容性极佳！

In recent years, Deltachem Specialty Chemicals Group has continuously paid attention to the application and development trends of polymer materials in the photovoltaic field, and has been constantly striving to provide customers with optimized solutions to the weather resistance problems of photovoltaic materials. For this reason, our company has launched a variety of high-transmittance and low-chromaticity UV absorbers, which have excellent compatibility with photovoltaic materials!

其中，欧稳德 UV312是一款UVB型紫外线吸收剂，在UVB波段表现出强烈的吸光度，吸收范围可覆盖250-350nm。因此UV312可高效吸收光伏材料中C-C、C-H键最敏感波段，从而阻断光老化发生。并且UV312色度低，在可见光波段透光率高，因此不会影响光伏胶颜色和透明度，这将大幅降低太阳光穿过胶膜时产生的损失，并避免光量下降，提升光伏器件的整体转化效率！

Among them, the OMNISATB UV312 is a UVB type ultraviolet absorber that exhibits a strong absorbance in the UVB band, with an absorption range covering 250-350nm. Therefore, UV312 can efficiently absorb the most sensitive bands of C-C and C-H bonds in photovoltaic materials, thereby blocking the occurrence of photoaging. Moreover, UV312 has a low chromaticity and a high light transmittance in the visible light band. Therefore, it will not affect the color and transparency of photovoltaic adhesives. This will significantly reduce the loss of sunlight passing through the adhesive film and prevent a decrease in light quantity, thereby enhancing the overall conversion efficiency of photovoltaic devices!
