Premier Energies Unveils India’s First Zero Busbar Solar Cell

Hyderabad-based Premier Energies Limited, an integrated solar manufacturer, has unveiled one of the first Zero Busbar (0BB) TOPCon Solar Cells in India at Intersolar Gandhinagar, thereby setting a new benchmark in solar cell technology. In a press release, Premier Energies explained that the Zero Busbar represents a structural shift from traditional 10BB and 16BB architectures. Moreover, it replaces the thick silver busbars with a dense matrix of ultra-fine silver lines to collect current. 

Sudhir Reddy, Chief Strategy Officer, Premier Energies, explained, “Zero Busbar is not an incremental upgrade; it is a redesign of solar cell engineering.”

Explaining the impact of the new product, Premier Energies said, “By lowering silver usage while enhancing efficiency and durability, we are strengthening both performance economics and sustainability in solar manufacturing. This achievement has reinforced our leadership  in next-generation solar technologies and our commitment to advancing India’s high-efficiency solar manufacturing ecosystem.” 

Reducing Silver Consumption 

Premier Energies said its latest Zero Busbar product reduces silver consumption, minimizes shading losses, and delivers higher power output compared with conventional designs. This is particularly important as prices of imported Chinese silver are rising due to the 9% value-added tax (VAT), which in turn adds to cost pressures for Indian manufacturers.

Premier Eneriges' latest product offers a 0BB structure, which also enhances mechanical flexibility, lowers cell interconnection stress, and improves resistance to micro-cracks. These attributes enable stronger long-term reliability and deliver superior performance in demanding Indian climate conditions, the company said.

Chandra Mauli Kumar, Chief Production Officer, Premier Energies, added, “Scaling 0BB  demanded significant manufacturing precision and process innovation. Our integrated  capabilities enable us to deliver enhanced crack tolerance, reduced interconnection  stress, and consistent performance in extreme temperatures.”
