Indian PV manufacturer EMMVEE has commissioned a 1.4 GW TOPCon solar cell production line, achieving cell efficiencies of up to 25.4% on M10 wafers. Following the ramp-up, German equipment suppliers involved in the project have secured follow-up orders from the company.

The production line incorporates equipment from Germany-based centrotherm, RENA Technologies and halm. The ramp-up was supported by the International Solar Energy Research Center Konstanz (ISC Konstanz), which provided process integration and technology transfer services in collaboration with EMMVEE and the equipment suppliers.

Having been active in solar module manufacturing for decades, EMMVEE has expanded upstream into solar cell production with the 1.4 GW TOPCon facility in Bengaluru. centrotherm coordinated the setup of the production line and engaged ISC Konstanz to support process integration and the technology ramp-up in early 2025.

“The successful ramp-up and the subsequent follow-up business demonstrate the value of close cooperation between equipment suppliers and technology experts,” says Dr. Helge Haverkamp, CTO of centrotherm. “Together, we have shown that German engineering can deliver outstanding results in highly competitive photovoltaic markets.”
