Premier Energies Limited has unveiled what it described as India’s first Zero Busbar (0BB) TOPCon solar cell at Intersolar Gandhinagar. The company said the development marks the introduction of a new cell architecture within its product portfolio.
According to the company, the Zero Busbar (0BB) design differs from conventional 10BB and 16BB solar cell architectures. Instead of using thick silver busbars for current collection, the 0BB structure uses a dense matrix of ultra-fine silver lines.
Premier Energies stated that this architecture reduces silver consumption and minimises shading losses compared to conventional multi-busbar designs. The company added that the design enables higher power output relative to traditional structures.
The company further said the 0BB configuration improves mechanical flexibility and reduces interconnection stress within the cell. It also stated that the structure enhances resistance to micro-cracks, which can affect long-term performance.
Premier Energies noted that these characteristics are intended to support long-term reliability and performance under Indian climatic conditions.
The product was unveiled during Intersolar Gandhinagar. Further details on commercial deployment timelines or production capacity were not disclosed in the announcement.
