描述
產(chǎn)品介紹(Introduction)
SA-6070S 系列鋁漿是雙面 PERC 太陽(yáng)能電池電池局域鋁背場(chǎng)的專(zhuān)用漿料，該漿料經(jīng)熱處理后能很好填充激光開(kāi)孔位置，在開(kāi)孔處形成良好的局域鋁背場(chǎng)。該鋁漿與背銀電極能形成良好的接觸， 同時(shí)， 不損傷背面 Al2 O3/SiNx 鈍化層， 電池片有較高的開(kāi)路電壓、較低的串聯(lián)電阻，綜合表現(xiàn)為有較高的轉(zhuǎn)換效率。鋁膜外觀顏色均勻、附著牢固，有很強(qiáng)的耐水煮特性， 具有可靠的長(zhǎng)期工作穩(wěn)定性能。
SA-6070S Al Paste is used for local BSF(back surface field) of bifacial PERC solar cells. This paste can form local Al-Si alloy by annealing and get an excellent contact with silver electrodes and won’t damage the Al 2O3/SiNx layers. The BSF made by SA-6070S10 results a higher solar cell efficiency. The aluminium layer has some characteristics such as strong adhesion, good conductivity, and very strong characteristic of resistance water boiling. There for, it has a very good long-term work stability.
