A champion device had a certified power conversion efficiency of 24.8% and an open-circuit voltage near the Shockley-Queisser limit. These devices could maintain more than 87% of the original power conversion efficiency under 50% relative humidity for more than 500 hours. Science, this issue p. 1615.

DISCUSSION. We developed an effective multisource sequential vacuum deposition approach to fabricate large-area, pinhole-free perovskite films, which, together with precursor optimization, enables us to achieve high-efficiency PSCs with PCEs of 24.42 and 23.44% for 0.1-cm 2 -area and 1-cm 2 -area devices, respectively.
