Fujiyama Plans 1.2 GW TOPCon Solar Cell Line at Ratlam, Madhya Pradesh
Expanding Domestic Cell Manufacturing
Fujiyama Power Systems has announced plans to set up a 1.2 GW TOPCon (Tunnel Oxide Passivated Contact) solar cell manufacturing line at Ratlam in Madhya Pradesh. The facility will produce N-type TOPCon cells with targeted efficiencies exceeding 25%, aligning with the global shift away from older PERC technology toward higher-performance cell architectures.
The investment is part of Fujiyama's broader strategy to become a vertically integrated solar manufacturer in India, covering wafers, cells, and modules. Madhya Pradesh offers competitive land costs, reliable power supply, and state-level incentives that complement the central PLI scheme for solar manufacturing.
Why TOPCon Matters
TOPCon cells deliver 1-2% higher absolute efficiency compared to PERC, translating to meaningfully more energy output per square metre of rooftop or ground-mounted area. For Indian conditions with high irradiance and elevated ambient temperatures, N-type TOPCon's superior temperature coefficient provides additional yield advantages. The technology is rapidly becoming the global standard, with Chinese manufacturers having already transitioned the majority of their capacity.
What It Means
India's cell manufacturing capacity has been the weakest link in the domestic solar value chain. Fujiyama's 1.2 GW line, along with similar investments by other firms under PLI, will narrow the gap between India's module assembly capacity and its upstream cell production, reducing import dependence on Chinese cells.
