On June 1st, Trina Solar announced that its independently developed perovskite/crystalline silicon tandem solar module, featuring an industry-standard size of 3.1 square meters, achieved a peak power output of 907W and a full-area module efficiency of 29.2%. Calibrated by the authoritative third-party testing organization TÜV SÜD, this milestone officially sets a new world record for the power output of global tandem modules.

It is reported that the successful development of this 907W ultra-high-power module relies primarily on Trina Solar's self-refined 210mm large-size tandem cell technology system. The R&D team overcame technical bottlenecks across multiple dimensions by improving the uniformity of the perovskite film, innovatively upgrading the interface passivation solution, and fine-tuning the adaptability of the tandem spectral absorption. These concerted efforts resulted in a dual leap in both the conversion efficiency and the operational stability of the tandem cells.

Furthermore, the module adopts a standardized industrial size design. Because it is fully compatible with universal industry technical standards, the module demonstrates an exceptionally high feasibility for practical technical application and commercialization.

As the solar industry continually pursues higher conversion efficiencies, crystalline silicon-perovskite tandem cells have emerged as the focal point for the next generation of technological advancement. Trina Solar's recent breakthrough to a 907W module power output not only pushes tandem module power beyond the 900W threshold for the very first time, but also further accelerates the march of perovskite tandem technology toward large-scale industrial application.
