The research article “Ultrastable and efficient slight-interlayer-displacement 2D Dion-Jacobson perovskite solar cells,” published in Nature Communications, addresses the stability issue in solution-processed perovskite photovoltaics. The study showcases that the ultrastable Dion-Jacobson perovskites, specifically (1,4-cyclohexanedimethanammonium)(methylammonium)n−1PbnI3n+1 (n ≥ 1), has achieved a 19.11% power conversion efficiency with blade-coated solar cells. The un-encapsulated cells retain 92% efficiency over 4,000 hours at ~90% relative humidity and exhibit minimal efficiency loss after 5,000 hours at 85°C and 6,000 hours at 45°C under continuous light illumination of 100 mW cm−2. This advancement demonstrates the potential of DJ perovskites in achieving high efficiency and long-term stability, essential for practical photovoltaic applications.
