Performance and Vulnerability of TOPCon Solar Modules Highlighted in New Studies

• JinkoSolar and Trina Solar report higher power generation in TOPCon modules than p-type rear contact PV modules.
• Tests by German agency TÜV Nord confirm JinkoSolar’s results, showing performance benefits in real-world conditions.
• Kiwa PVEL’s 2023 scorecard reveals reliability concerns, with a 41% failure rate at the BOM level – the highest recorded.
• University of New South Wales research underscores TOPCon’s susceptibility to contact corrosion.
• Thermal and damp heat tests by Kiwa PVEL highlight degradation issues, especially for TOPCon modules compared to PERC.
• TOPCon technology shows promise but faces long-term durability challenges that require enhanced testing for reliability.
