MBB (Multi-busbar) half-cut cell is an optimized design of solar cell, which uses multiple copper wires to form shorter current paths on a solar cell for improvement of current collection efficiency. Compared to traditional flat copper ribbons, copper wires of circular design are utilized to increase the amount of light incident on the solar cells. In addition, the half-cut cell design can reduce shading effect and loss from electrical resistance, as well as lower the impact of micro-cracks on the solar cells. Hence, the power generation performance of module is improved further. In addition, by using the multi-busbar design, the impact of external force on solar cell can be reduced effectively, and the range of micro cracks is limited to prevent current transmission path (current distribution) from further damage, so that the solar module can maintain a stable output performance for a long period of time. Thus, this is a new generation technology that enhances both power performance and reliability simultaneously. SunBravo PM060MW6 and PM072MW6 are all high-efficiency solar modules using multi-busbar half-cut cell technology.
