We provide the first NREL‐certified efficiency measurement on an all‐inorganic, solution‐processed, nanocrystal solar cell. The 3% efficient device is composed of ZnO nanocrystals and 1.3 eV PbS quantum dots with gold as the top contact. This configuration yields a stable device, retaining 95% of the starting efficiency after a 1000‐hour light soak in air without encapsulation.
