Hyderabad: Premier Energies Limited, one of India’s largest integrated solar manufacturers, unveiled India’s first Zero Busbar (0BB) TOPCon Solar Cell at Intersolar Gandhinagar on Thursday, setting a new benchmark in advanced solar cell technology. Zero Busbar represents a structural shift from traditional 10BB and 16BB architectures. It replaces the use of thick silver busbars with a dense matrix of ultra-fine silver lines to collect current.
This next-generation architecture significantly reduces silver consumption, minimizes shading losses, and delivers higher power output compared to conventional designs. The 0BB structure also enhances mechanical flexibility, lowers cell interconnection stress and improves resistance to micro-cracks. These attributes enable stronger long-term reliability and superior performance in demanding Indian climates.
“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, 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.”
