The photon absorption can be enhanced by immobilization of surfactant-stabilized Au NPs on a self-assembled monolayer- modi ?ed indium tin oxide (ITO) electrode, and thus, the photocurrent as well as the power conversion e ?ciency (PCE) of these OPVs can be improved. Varying the density of the immobilized Au NPs in the devices provided no signi ?cant variation in the charge mobility but it did enhance the photocurrent. In addition, device simulation results demonstrated that the improvement in photocurrent was due to the enhancement of light absorption and the increase in charge separation, which was facilitated by the Au NPs. Overall, we attributed the i
