Premier Energies Unveils Zero Busbar TOPCon Solar Cell at Intersolar Gandhinagar

Premier Energies, an integrated solar manufacturing company, has unveiled Zero Busbar (0BB) TOPCon Solar Cell at Intersolar Gandhinagar, advancing in 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, minimises 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. 

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