描述
產(chǎn)品介紹(Description)
SA-6171D 系列 PERC 背銀漿是我公司推出的一款低耗量、高附著力硅太陽(yáng)能電池背銀漿料，按照固含量不同可分為 SA-6171D18、SA-6171D62 和 SA-6171D65 等產(chǎn)品，具有優(yōu)異的附著力、良好的可焊性和耐焊性、寬的燒結(jié)工藝窗口、卓越的抗老化能力和電池轉(zhuǎn)換效率高等優(yōu)點(diǎn)。
SA-6171D Series PERC Ag Paste is a new perc rear side silver paste series for silicon solar cells. According to solid content, it is divided into SA-6171D18，SA-6171D62 and SA-6171D65. This paste has some characteristics such as good soldered adhesion, excellent solderability, wide co-firing process window and outstanding anti-aging ability. Solar cells made by using SA-6171D will have a higher efficiency.
