Risen Energy's Breakthrough: 30.99% Efficiency in HJT-Perovskite Tandem Solar Cells

In a groundbreaking achievement, Risen Energy has pushed the boundaries of solar technology by attaining an impressive 30.99% power conversion efficiency in heterojunction technology (HJT) perovskite tandem solar cells. This remarkable feat, certified by the Chinese National Solar Photovoltaic Product Quality Supervision and Inspection Center, positions Risen Energy at the forefront of the global solar energy market.

The company's Global Photovoltaic Research Institute, led by Director Yang Bochuan, has successfully developed a tandem solar cell comprising a top perovskite cell and a bottom silicon HJT cell. This innovative design leverages the unique structural advantages of HJT cells, which use indium tin oxide (ITO) as a transparent conductive layer, enabling easier integration of tandem cells and enhancing overall performance.



Risen Energy's achievement is a significant milestone in the development of perovskite-silicon tandem solar cells, surpassing the 24.5% efficiency of the first commercial silicon-perovskite tandem modules shipped by Oxford PV in 2023. This high efficiency demonstrates Risen Energy's technological prowess and its potential to compete in the global solar energy market.

The company's success in developing high-efficiency tandem solar cells can attract further investment and support from stakeholders, enabling Risen Energy to expand its operations and strengthen its position in the global solar energy market. The high efficiency of its tandem solar cells can lead to lower levelized cost of energy (LCOE) and improved performance compared to traditional silicon solar cells, making Risen Energy's products more attractive to customers.

Risen Energy is committed to addressing the challenges associated with the stability and scalability of perovskite solar cells. The company is focused on improving the operational lifetime of perovskite cells by decreasing their reactivity and finding alternative materials for formulations. Additionally, Risen Energy is pioneering the use of nano-encapsulation and self-healing materials to address the durability gap of perovskite cells.

The company's existing HJT cell production lines feature forward-looking technological compatibility, enabling direct integration of perovskite cell equipment without requiring modifications. This approach allows for co-production of perovskite and silicon-based cells on the same line while maintaining existing operations, safeguarding prior investments and maximizing production line utilization.

Risen Energy's breakthrough in HJT-perovskite tandem solar cells highlights the company's commitment to innovation and its ability to drive the development of next-generation solar technologies. By addressing the challenges associated with perovskite solar cells and leveraging the advantages of HJT technology, Risen Energy is poised to make a significant impact on the global solar energy market.

As the world transitions towards renewable energy sources, Risen Energy's high-efficiency tandem solar cells offer a promising solution for generating clean, affordable, and sustainable electricity. The company's achievements serve as a testament to the potential of perovskite-silicon tandem solar cells and the importance of continued investment in research and development in the solar energy sector.
