A facile and efficient synthesis of a solution‐processable MoO 3 /MoS 2 featuring uniformly decorated MoO 3 nanoparticles onto exfoliated MoS 2 nanosheets is realized via a one‐step oxidation and spontaneous exfoliation method using hydrogen peroxide. By using MoO 3 /MoS 2 as a hole extraction layer in organic solar cells, high efficiencies, regardless of annealing conditions of the interfacial layer, and excellent long‐term stability are demonstrated.
