The road ahead for perovskites The high power conversion efficiencies of small-area perovskite solar cells (PSCs) have driven interest in the development of commercial devices. Rong et al. review recent progress in addressing stability, how to allow mass production, and how to maintain uniformity of large-area films. They note that lifetimes exceeding 10,000 hours under 1 sun (1 kW/m2) illumination have been reported for printable triple mesoscopic PSCs. Science, this issue p. eaat8235…
