TOPCon has rapidly become the mainstream successor to PERC in global PV manufacturing .i-TOPCon (industrial Tunnel Oxide Passivated Contact) technology introduces: An ultra-thin tunnel oxide layer Highly doped polysilicon passivation Reduced recombination losses Higher open-circuit voltage (Voc) This results in: Higher conversion efficiency Improved temperature coefficients Exceptional performance stability over time. 1 N-Type vs. P-Type Cells Traditional P-Type PERC modules suffer from: Light-Induced Degradation (LID) Light- and elevated Temperature-Induced Degradation (LeTID) Faster long-term performance decline By contrast, N-Type cells offer: Near-zero LID and LeTID Higher carrier lifetime Superior low-light and high-temperature performance Higher long-term energy yield

Trina Solar Vertex N Series N-Type i-TOPCon Bifacial Dual Glass Modules (TSM-NEG2) Engineering the Next Standard for High-Performance, Bankable Solar Assets 1. Introduction: From Nameplate Power to Long-Term Energy Value As the global photovoltaic (PV) industry matures, project success is no longer defined by headline wattage alone. Developers, investors, and grid operators increasingly prioritize lifetime energy yield, degradation control, bankability, and levelized cost of energy (LCOE). In this new landscape, advanced cell technologies and system-level optimization have become decisive factors. Trina Solar’s Vertex N Series, built on N-Type i-TOPCon bifacial dual-glass architecture, represents a decisive step toward this next phase of solar development. Rather than focusing solely on peak output, Vertex N modules are engineered to deliver stable, predictable, and superior energy production over 30 years, making them ideally suited for utility-scale, commercial, and industrial (C&I) solar projects worldwide.
