Researchers in China have developed a perovskite solar cell (PSC) with improved stability by incorporating a ~7 nm polymeric interlayer (D18) between the perovskite layer and the hole-transport layer (HTL). The interlayer inhibits ion diffusion, preventing degradation of the HTL and perovskite components while enhancing energy-level alignment and hole extraction efficiency. The study, published in Nature Communications, reports certified efficiencies of 26.17% for a 0.12 cm² aperture and 25.02% for a 1.00 cm² aperture. After 1,100 hours of operation under maximum power point tracking, the PSCs retained 95.4% of their initial efficiency, addressing challenges of reduced operational lifetimes in n-i-p structure PSCs.
