Wuxi, China – April 10, 2024 – Trina Solar, a global leader in photovoltaic (PV) modules and smart energy solutions, announced today a groundbreaking achievement in solar cell technology. The company’s State Key Laboratory of PV Science and Technology, located in Wuxi, has achieved a record-breaking 31.1% efficiency for its large-area (210mm) perovskite-silicon tandem solar cell. This milestone, independently certified by Fraunhofer ISE CalLab in Germany, marks a significant step forward in the pursuit of higher efficiency and lower-cost solar energy.
The announcement marks Trina Solar’s 32nd world record in the solar energy sector, underscoring its commitment to innovation and technological advancement.
Pushing the Boundaries of Solar Cell Efficiency
The 31.1% efficiency was achieved using a 210mm x 105mm² high-efficiency crystalline silicon solar cell as the bottom cell, upon which the perovskite top cell was layered. Trina Solar’s research and development team focused on developing mass-producible processes, tackling key technical challenges such as large-area perovskite film formation on textured substrates, top and bottom cell matching, and interface passivation to minimize optoelectronic losses.
This achievement demonstrates Trina Solar’s unwavering dedication to pushing the boundaries of solar cell technology, said [Insert Name and Title of Trina Solar Spokesperson – This information is not provided in the source material and should be researched and added]. By overcoming critical technical hurdles, we have not only achieved a new world record but also paved the way for the commercialization of high-efficiency perovskite-silicon tandem solar cells.
The Promise of Perovskite-Silicon Tandem Technology
Perovskite-silicon tandem solar cells offer the potential to surpass the theoretical efficiency limits of single-junction silicon solar cells. While single-junction silicon cells have a theoretical efficiency limit of around 29%, tandem cells, which combine two different light-absorbing materials, can achieve efficiencies exceeding 43%. This higher efficiency translates to more electricity generated per unit area, reducing the overall cost of solar energy.
Furthermore, perovskite solar cells are versatile and can be integrated into various applications, including Building Integrated Photovoltaics (BIPV), Building Applied Photovoltaics (BAPV), and Building-Top Photovoltaics (BTPV), expanding the possibilities for solar energy adoption. Trina Solar has developed what is believed to be the largest industrial-grade tandem solar cell of its kind.
Looking Ahead
Trina Solar’s latest achievement underscores the growing importance of perovskite-silicon tandem technology in the future of solar energy. As the world seeks cleaner and more sustainable energy sources, advancements like this will play a crucial role in driving down costs and accelerating the adoption of solar power. The company’s continued investment in research and development positions it as a key player in shaping the future of the solar industry.
