Our partners at UCSB have developed a method to produce high-quality perovskite films at room temperature, achieving a power conversion efficiency of 24.4% in perovskite solar cells. This process eliminates the need for thermal annealing and additional post-treatments, making it more versatile and applicable to non-traditional substrates like plant leaves. By using a specific perovskite composition and an organic linker, the team optimized the film’s growth and improved device performance. This room-temperature method not only surpasses previous efficiency records for low-temperature perovskite solar cells but also opens the door to new applications, including semi-transparent solar cells for integration into windows and vehicles, as well as indoor solar cells with potential efficiencies over 40% under LED lighting.
