TOPCon Architecture Becomes Default Utility-Scale Specification
Utility-scale buyers increasingly default to TOPCon cell architecture over legacy PERC designs, driven by meaningfully higher conversion efficiency and better bifacial gain performance that improves real-world energy yield across large installation portfolios. Roughly 68 percent of new utility-scale cell procurement specified TOPCon architecture in 2025, up from under 25 percent three years earlier, as buyers prioritize the yield improvement these designs provide. This shift is reshaping capacity investment decisions across nearly every major manufacturing base serving utility customers specifically. Producers still running older PERC-only lines without a TOPCon conversion roadmap are losing utility specification share faster than expected.
Market Impact: Grew 16 percent in 2025
