Huasun unveils zero busbar technology for high-efficiency solar modules

Huasun Energy introduced high-efficiency modules with zero busbar (0BB) technology. This advancement has been integrated into Huasun’s mass production lines, including the Himalaya G12 series and Everest G12R rectangular series of large-format modules. In the manufacturing process of 0BB cells, Huasun utilizes a simpler two-step SP printing technology for superior product quality and enhanced electrical and CTM performance, demonstrating advantages over SMBB products. The design reduces metal coverage on the back, expanding the light-receiving area and achieving bifaciality of up to 90%. The implementation of fine ribbons and low-weight encapsulants reduces production costs. The 0BB technology supports the trend towards thinner silicon wafers by providing higher reliability with no main grid, thinner ribbons, minimal stress, and lower fragmentation rates.
