Here we report ambient-air, blade-coated perovskite solar cells and modules that achieve power conversion efficiencies of 26.6% (26.5% certified) and 23.2%, respectively. These devices demonstrate exceptional stability, retaining 99.8% of their initial power conversion efficiency after 1,200 hours of continuous light soaking.
