After adhesive printing on ribbon positions on the front and back sides of the cells, the cells are connected in series by ribbons and form a string after adhesive curing.
The technology enables 0BB mass production and greatly reduces cell printing costs.Module-level ribbon diameter change and adhesive costs are also lower than SMBB. Moreover, 0BB pad design boosts module power output, and low-temperature cursing improves CTM efficiency, offering a particularly perfect solution for HJT technology.
