Researchers at Shanghai Jiao Tong University have developed a new type of tin-based perovskite solar cell, achieving a remarkable power conversion efficiency of 17.7%. This achievement was reported on October 16, 2025, by The Paper. The development team at Shanghai Jiao Tong University, in collaboration with the Future Energy Research Institute, has successfully produced this innovative solar cell, which has shown great potential for commercial applications without the usual degradation issues associated with existing technologies.
The solar cell, titled “Tin-based perovskite solar cells with a homogeneous buried interface”, was featured in the journal Nature on October 15. The research presents a breakthrough in enhancing the stability and efficiency of perovskite solar cells, which have been gaining attention for their promising performance in renewable energy applications.
In the realm of renewable resources, tin-based perovskite solar cells are positioned as a strong contender due to their high efficiency and lower material costs. They are engineered to be the next generation of solar technology, providing substantial improvements over traditional silicon-based cells. However, the key challenge remains ensuring the stability of these cells in real-world conditions.
The researchers emphasized that the target is to create a truly green solar cell that is both efficient and sustainable in the long run. They aim to stabilize the solar cells against environmental factors while maintaining high performance efficiency. This approach will help address issues related to resource scarcity and environmental impact.
After five years of research focused on overcoming the limitations of current technologies, the team successfully developed a systematic method that combines material stability with efficient energy conversion. The new technology has been validated through rigorous testing, achieving a conversion efficiency of 17.7%, surpassing the previous record of approximately 16.5% for tin-based perovskite solar cells.
According to the researchers, this advancement positions tin-based perovskite solar cells at the forefront of solar energy technology, making them the first in the world to reach this efficiency level. They also noted that the innovation could potentially lead to broader adoption in various applications, including electric vehicles, where direct integration of these solar cells could provide a stable power source.
Looking ahead, the team plans to collaborate with industry partners to commercialize this technology, striving to scale up production and implement it in real-world applications. The future of this green technology appears promising, with potential integrations in electric vehicles and other energy systems that enhance sustainability.
The research team expressed their commitment to developing efficient and environmentally friendly solar solutions that meet the growing energy demands without compromising ecological integrity.
