BC (Back-Contact) battery-onlyPhotovoltaic welding ribbon<\/a>A series of features are required to meet this advancedPhotovoltaic cells<\/a>Technology requirements:<\/p>\n

1. High conductivity: One of the characteristics of BC cells is that the electrode is located on the back of the cell, so the photovoltaic ribbon must have excellent conductivity to ensure that the current can be conducted efficiently.<\/p>\n

2. Thin and wide design: The electrodes of BC cells are usually wider and thinner than traditional cells. Therefore, the design of the photovoltaic ribbon needs to adapt to these special dimensions to ensure the accuracy and firmness of the welding.<\/p>\n

3. Good corrosion resistance: Since the electrodes of BC cells are located on the back of the cells, the photovoltaic ribbons may be subject to different environmental conditions and potential corrosion threats. Therefore, the ribbons need to be corrosion-resistant to ensure long-term reliable performance.<\/p>\n

4. High temperature stability: BC cells usually operate at high temperatures, so photovoltaic ribbons need to have excellent high temperature stability to prevent performance degradation.<\/p>\n
