The global solar industry has reached a pivotal moment as Trina Solar officially announced two staggering world records in perovskite-crystalline silicon tandem solar technology. As the world transitions toward renewable energy, the efficiency of solar panels has become the ultimate benchmark for success. Trina Solar’s latest breakthrough—achieving a certified power conversion efficiency of 32.6% for industrial-scale tandem cells and a peak power output of 865 W for tandem modules—proves that the next generation of photovoltaics (PV) is no longer a distant dream but a commercial reality.
A New Era for Tandem Solar Cells
For years, the solar industry has relied on crystalline silicon technologies like TOPCon and heterojunction. However, these technologies are rapidly approaching their theoretical efficiency limits. To break through this ceiling, researchers have turned to tandem architectures, which layer perovskite materials on top of traditional silicon. This “best of both worlds” approach allows the cell to capture a wider spectrum of sunlight, significantly boosting energy harvest.
Trina Solar’s record-breaking tandem cell utilizes a 210 mm half-cut format, an industrial standard that ensures these results can be replicated in mass production. Certified by the prestigious Fraunhofer Institute for Solar Energy Systems (ISE) CalLab, the 32.6% efficiency rating places Trina Solar at the forefront of the global race for high-efficiency solar.
Powering the Future: The 865 W Tandem Module
While high efficiency in a laboratory setting is impressive, the real challenge lies in scaling that technology to a full-sized module. Trina Solar has successfully bridged this gap. Their new tandem module, which spans an area of 3.1 square meters (aligning with mainstream utility-scale designs), has been certified by TÜV SÜD with a peak power output of 865 W.
This achievement is monumental for utility-scale solar projects. Higher power output per module means:
- Reduced BOS (Balance of System) Costs: Fewer modules, racks, and cables are needed to achieve the same energy capacity.
- Higher Land Efficiency: Projects can generate more electricity on the same footprint, a critical factor for regions with limited space.
- Accelerated ROI: Enhanced efficiency leads to faster returns for investors and lower Levelized Cost of Energy (LCOE).
Collaborative Innovation: The Secret to Success
These milestones were not achieved in isolation. The project was a joint effort between Trina Solar’s Photovoltaic Science and Technology National Key Laboratory and China’s Huairou Laboratory. While Huairou Laboratory focused on the fundamental science of perovskite absorbers and functional layer materials, Trina Solar applied its expertise in industrial process integration and large-area fabrication.
Dr. Yifeng Chen, Vice President of Trina Solar, emphasized that these results demonstrate the “commercial potential of tandem architectures beyond laboratory prototypes.” This focus on industrial-relevant formats is what sets Trina Solar apart from competitors, as it ensures that the technology can move from the lab to the factory floor without losing performance.
37 World Records and Counting
Trina Solar’s commitment to R&D is legendary in the PV sector. With these two new milestones, the company has now created or broken global benchmarks in solar cell efficiency and module power output a total of 37 times. This track record of consistent innovation solidifies their position as a leader in the energy transition.
As the industry looks toward 2026 and beyond, the focus will shift to the long-term stability of perovskite materials. However, by proving that industrial-scale tandem cells can achieve such high efficiency and power today, Trina Solar has cleared one of the biggest hurdles standing in the way of the solar-powered future.
Summary:
Trina Solar’s record-breaking 32.6% efficiency and 865W output signal a major leap in tandem PV technology, proving that industrial-scale perovskite-silicon integration is the future of high-performance solar energy.
