YD****0AD Al paste is used for BSF(back surface field) of Si solar
cells. This paste can form Al-Si alloy by annealing and get an
excellent ohmic contact with Silicon wafers with some
characteristics such as strong adherence, good conductivity, and
homogeneous thick layer. The BSF made by YD****5AD results a higher
solar cell efficiency.
