Trinasolar has achieved a new milestone for perovskite/crystalline silicon tandem solar modules, hitting a peak power output of 907W with a full-area efficiency of 29.2%. The performance figure has been independently certified by Germany’s TÜV SÜD, marking the firm’s 41st global record in photovoltaic technology.

The company’s tandem module power rating has seen rapid growth over just more than one year: up from 808W in March 2025 to 829W in June 2025, and now reaching the new high of 907W. The breakthrough relies on Trinasolar’s self-developed 210mm large-area tandem cell platform.

Its R&D team resolved core bottlenecks restricting perovskite commercialization via three major technical optimizations: enhanced uniformity of perovskite thin films, upgraded interface passivation technologies, and optimized spectral absorption matching for tandem structures. The upgrades simultaneously lift conversion efficiency and long-term operational stability, a historic pain point for perovskite-based products.

Notably, the record-setting tandem module adopts standard industrial dimensions consistent with mainstream industry standards, proving robust scalability and commercial viability instead of remaining limited to lab prototypes.

Separately at SNEC 2026 last week, Trinasolar sealed a 600MW module distribution memorandum of understanding (MoU) with Ecohope Solar, a supplier of PV and energy storage system solutions.
