PVTIME – In a significant development that has sent ripples through the photovoltaic industry, Trina Solar’s National Key Laboratory of Photovoltaic Science and Technology made an exciting revelation on 23 March. The laboratory’s achievement in developing a 3.1 square metre, 210-unit perovskite-silicon dual-junction tandem module has been officially validated by the internationally renowned TÜV SÜD. With a peak power output of an impressive 808W, this module has become the world’s first industry-standard photovoltaic module to surpass the 800W power milestone. This remarkable achievement not only marks the 31st time Trina Solar has broken the world record for solar cell conversion efficiency and module power, but also ushers in a new era, marking a significant leap from the “silicon-based era” to the “perovskite tandem era” of photovoltaic technology.
Trina Solar’s journey towards this breakthrough has been a long and dedicated one. Since 2014, the company has been deeply involved in researching perovskite tandem technology. It took the initiative to form strategic partnerships with renowned universities and research institutes, such as Nanjing University and Nankai University. Together, they undertook major scientific endeavours, including Jiangsu Province’s science and technology support projects and national key research and development programmes. Through relentless efforts and continuous technological innovation, Trina Solar has amassed an impressive portfolio of 331 related patents. These patents cover the entire spectrum from material research and development to process optimisation, demonstrating the company’s comprehensive technological capabilities.
This latest achievement is not an isolated success, but rather a testament to Trina Solar’s continued leadership in the photovoltaic technology race. Over the past three years, the company has continued to push the boundaries, breaking efficiency records for various cell modules, including TOPCon and HJT. These continuous improvements have solidified Trina Solar’s position as an industry leader.
The significance of Trina Solar’s breakthrough is even more pronounced in the context of the current global energy landscape. As the world accelerates its transition to renewable energy, PV is at the forefront as a key driver. However, it faces the pressing challenge of overcoming the twin hurdles of efficiency and cost. Perovskite tandem technology, with its inherent advantages of high theoretical efficiency and low material cost, has emerged as a promising core direction for the next generation of PV technology.
Trina Solar’s latest achievement has far-reaching implications. By setting a new performance benchmark for the industry, it not only raises the bar for competitors, but also provides a clear roadmap for the development of photovoltaic technology. It also bridges the gap between laboratory research and large-scale production of tandem modules, opening up exciting possibilities for the widespread adoption of high-efficiency photovoltaic power generation. This could potentially revolutionise the way we use solar energy and play a key role in achieving a sustainable energy future.
