高固含晶体硅太阳能电池双面铝浆研究
Study on Bifacial Aluminum Paste for High Solid Crystalline Silicon Solar Cells
摘要: 为研发出更高固含量的铝浆，将苯乙烯–马来酸酐共聚物(SMA)引入到铝浆中，多角度表征并分析了SMA对铝浆性能的影响。流变性能测试和沉降实验结果表明：SMA分子通过吸附在铝粉表面以提高铝浆的分散性和稳定性，添加量为0.6% (质量分数)时效果最好。当固含量为80%的铝浆中含有SMA时，浆料具有良好的印刷性，铝栅线线宽约148.13 μm，线电阻率约1.3 × 10−5 Ω·cm。
Abstract: In order to develop aluminum pastes with higher solid content, Styrene-maleic anhydride copolymer (SMA) was introduced into Al pastes, and the effect of SMA on the properties of Al pastes was characterized and analyzed from multiple angles. The results of rheological property test and sedimentation experiment show that SMA molecules are adsorbed on the surface of aluminum powders to improve the dispersion and stability of Al pastes. The effect is the best when the addition amount is 0.6% (mass fraction). When SMA is contained in the Al Pastes with 80% solid content, the slurry has good printability, and the Al grid line width is about 148.13 μm and the line resistivity is about 1.3 × 10−5 Ω·cm.
