On April 8, 2014, Trina Solar made a significant announcement, revealing that its monocrystalline silicon photovoltaic module—featuring 60 cells measuring 156 mm x 156 mm—has set a new world record for the output power of P-type monocrystalline modules. This achievement was independently verified by TUV Rheinland, a renowned third-party certification body, with the peak power output (Pmax) reaching an impressive 326.3 watts. This breakthrough confirms that Trina Solar’s mass-produced PERC (Passivated Emitter Rear Cell) high-performance modules have reached the pinnacle of global innovation.
The module that achieved this record was developed using the research platform of the China National Key Laboratory of Photovoltaic Science and Technology at Trina Solar. It utilizes Honey Ultra, a pilot-scale mass production technology for ultra-high-efficiency monocrystalline solar cells. This advancement marks a major step forward in the company’s ongoing efforts to push the boundaries of solar efficiency.
Honey Ultra, the second-generation iteration of Trina Solar’s Honey technology, previously set a world record for polysilicon modules in May 2012. At that time, the peak power output of high-efficiency components based on 60 156 mm x 156 mm cells reached 284.7 watts. The current Honey Ultra modules represent a significant evolution, incorporating multiple proprietary technologies such as advanced battery back passivation, anti-reflective coating, and low-resistance interconnection techniques.
All of these high-efficiency modules are built on a foundation of self-developed intellectual property, ensuring that Trina Solar maintains a competitive edge in the global solar market. Since the acceptance of the industry’s key laboratory for photovoltaic science and technology in November 2013, the company has made remarkable progress. In particular, it has achieved a 24.4% efficiency rate for Back Contact Interdigitated Back Contact (IBC) cells, marking another critical milestone in the development of high-performance solar technology.
This breakthrough signals that PERC-based monocrystalline modules are now ready for large-scale commercial deployment. As these high-efficiency modules become more widely adopted, they are expected to significantly boost the performance and cost-effectiveness of solar energy systems across the photovoltaic industry.
Dr. Feng Zhiqiang, Vice President of Trina Solar Technology and Director of the State Key Laboratory of Photovoltaic Science and Technology, emphasized the company’s commitment to advancing high-efficiency solar cell technology through its state-of-the-art R&D platform. Over the years, Trina Solar has successfully developed a range of innovative, high-quality products with independent intellectual property rights. The company continues to lead in invention patent applications and authorizations, maintaining its position at the forefront of technological innovation.
Looking ahead, Trina Solar remains dedicated to accelerating the widespread adoption of affordable solar energy. By pushing the boundaries of efficiency and performance, the company aims to drive the transition toward a cleaner, more sustainable energy future for humanity.
