The cells incorporate a Zero Busbar (0BB) architecture that eliminates conventional busbars, reducing shading losses and increasing the active area available for light absorption. This design improves current collection efficiency, resulting in higher cell efficiency and enhanced power generation. Reduced silver consumption during manufacturing helps optimise material usage and production costs. AI-enabled manufacturing processes support greater production accuracy through automated inspection and defect detection systems. Improved module reliability is achieved by reducing stress concentration within the cell structure, while advanced interconnection technology enhances current flow and minimises resistive losses for better overall performance.
