Premier Energies Launches India’s First Zero Busbar Solar Cell Technology

Premier Energies Limited has unveiled India’s first Zero Busbar (0BB) TOPCon solar cell, marking a significant advancement in domestic solar manufacturing technology. The new architecture represents a shift from conventional busbar designs and is expected to improve efficiency and long-term reliability. 

The development strengthens the company’s focus on next-generation solar technologies and supports India’s push towards high-efficiency solar manufacturing. 

Zero Busbar Solar Technology 

The Zero Busbar architecture replaces traditional thick silver busbars with a dense network of ultra-fine silver lines for current collection. This structure helps reduce silver consumption while improving electrical performance. 

The design also lowers shading losses and increases power output compared with conventional 10BB and 16BB solar cell structures. Improved mechanical flexibility enhances durability under demanding operating conditions. 

The architecture is designed to reduce interconnection stress and improve resistance to micro-cracks, enabling more reliable performance in varying climatic conditions. 

Management Commentary and Expansion Plans 

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

Chandra Mauli Kumar, Chief Production Officer, Premier Energies, said, “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.” 

The company is currently undertaking a ₹12,500 crore capital expenditure programme over three years to expand solar manufacturing capacity and strengthen backward integration into ingot and wafer production.
