描述
产品介绍(Introduction)
SA-5071银浆是光-伏电池的正面电极专用浆料，具有附着力强、导电性好、电极表面均匀致密、可焊性好、电池转换效率高等优点。该浆料可与SA-6071银铝浆和SA-6070铝浆配套使用，采用同一工艺一次烧结，提高生产效率，降低生产成本。
SA-5071 Silver Paste is used for grid electrodes of Si solar cells, characterized by strong adhesion, excellent conductivity and good solderability. Solar cells made by using SA-5071 will have a higher efficiency. This paste can also be used together with SA-6071 Ag-Al paste and SA-6070 Al paste and co-fired, therefore, the productivity would be increased and the cost would be reduced.
