Premier Energies Limited has introduced what it calls India’s first zero busbar (0BB) solar cell
Based on TOPCon technology, the 0BB design replaces traditional multi-busbar (10BB and 16BB) structures
The company says that, with this new configuration, it attempts to boost performance economics and sustainability in solar manufacturing
Indian solar PV manufacturer Premier Energies Limited has launched what it says is India’s ‘1st’ zero busbar solar cell based on TOPCon technology.
Zero busbar, or 0BB, is the buzzword among solar PV manufacturers globally since it replaces thick silver busbars with ultra-fine silver lines, thereby reducing silver consumption and thus costs. It is also believed to minimize shading losses while boosting power output.
Traditionally, solar cells have relied on a multi-busbar (MBB) structure with 10BB and 16BB architectures.
Premier Energies Chief Strategy Officer Sudhir Reddy said, “By lowering silver usage while enhancing efficiency and durability, we are strengthening both performance economics and sustainability in solar manufacturing.”
While the manufacturer does not reveal any other technical details in an official statement, Premier Energies Chief Production Officer Chandra Mauli Kumar shared that scaling 0BB demanded significant manufacturing precision and process innovation.
Speaking at the TaiyangNews High-Efficiency Solar Technologies 2024 Conference, Forschungszentrum Jülich’s Kaining Ding had stressed that manufacturers must shift to 0BB to boost efficiency (see Manufacturers Must Shift To Zero Busbar To Reduce Costs & Improve Efficiency).
Premier Energies operates 3.6 GW of solar cell and 5.1 GW of module production capacity. By September 2026, it targets to expand the same to 10.6 GW and 11.1 GW, respectively. The manufacturer is also venturing into ingot production with 10 GW capacity targeted by FY2028 (see Premier Energies Commissions 400 MW Solar Cell Factory).
As part of an executive panel at the TaiyangNews STC.I 2026 in New Delhi recently, Reddy stressed that Indian companies invest in R&D to improve TOPCon or to explore new technologies like back contact to ensure cost competitiveness and quality (see Integration & Scale Key To Competing In Solar Manufacturing).
