Researchers from the Chinese Academy of Sciences (CAS) have made a breakthrough in perovskite solar cells, achieving an efficiency of 26.08%. This marks a significant advancement in the field of solar energy, as perovskite materials are known for their potential to surpass the performance of traditional silicon-based solar cells.
The research team developed a method to address the degradation and instability caused by ultraviolet (UV) radiation. By applying a molecular-induced strain regulation strategy, they integrated a UV-blocking molecule into the perovskite film. This approach not only protected the material from UV damage but also passivated defects, enhancing the stability and efficiency of the solar cells.
The result was a 26.08% certified efficiency and an open-circuit voltage of 1.201V, pushing the boundaries of what is achievable with perovskite solar technology. This development holds promise for the future of high-efficiency solar power and further application in the energy sector.
