A facile and efficient synthesis of a solution-processable MoO3/MoS2 featuring uniformly decorated MoO3 nanoparticles onto exfoliated MoS2 nanosheets is realized via a one-step oxidation and spontaneous exfoliation method using hydrogen peroxide. By using MoO3/MoS2 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.
