Runergy introduced its next-generation TOPCon cell with a certified conversion efficiency of 26.9% at Intersolar Europe 2026
The full-area bifacial cell incorporates upgrades in passivation, cell architecture, and manufacturing processes
The company offers modules based on its TOPCon and PERC module portfolio
Chinese solar cell and module manufacturer Runergy introduced its next-generation TOPCon cell technology at Intersolar Europe 2026. According to the company, its full-area bifacial n-type TOPCon cell achieved a certified conversion efficiency of 26.9%, following independent verification by Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). The company states that the efficiency was measured on a full-area bifacial cell rather than a designated active area. It attributes the improvement to advances in cell architecture, passivation, and manufacturing processes.
According to the company, the new cell platform combines 3 technology developments. The first is RunPass, its proprietary rear-side passivation process, which is designed to reduce carrier recombination losses and improve open-circuit voltage. The second combines high-sheet-resistance diffusion with hydrogen passivation on the front side to reduce surface recombination and improve carrier collection. The third is the Powerloss in-house real-time analysis system that identifies efficiency losses across the manufacturing process to support process optimization. According to Runergy, the combined improvements also enhance wafer-edge uniformity, contributing to higher cell efficiency.
The company did not disclose module specifications based on the new cell technology platform. The TaiyangNews TOP SOLAR MODULES listing includes 2 commercially available Runergy modules based on TOPCon and PERC technologies. Its HY-DH144N8 Plus bifacial dual-glass TOPCon module delivers up to 600 W with a module efficiency of 23.2%. Built with 144 half-cut 182 mm n-type cells, the module features 80±5% bifaciality and is backed by a 12-year product warranty and a 30-year linear performance warranty.
The company’s HY-WH144P8 p-type PERC module series delivers up to 560 W with 21.7% module efficiency. The 144 half-cut cell module uses 3.2 mm anti-reflective tempered front glass and carries a 12-year product warranty and a 25-year linear performance warranty.
