MoS 2 as a graphene‐like 2 D material shows a large potential to replace and even overcome graphene in various important applications owing to its ideal properties of electrical, optical, frictional, and tunable band gap. However, its low solubility in the most of common solvents makes it difficult to prepare by a simple solution process. Here, we introduce a metal–organic compound to modify MoS 2 . Phenyl acetylene silver (PAS)‐functionalized MoS 2 is easily dispersed in solvents like DMF and water. A conductive polymer PEDOT:PSS (poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate) blend with the MoS 2 leads to a significant enhancement of the performance of planar heterojunction perovskite solar cells. The solar cells have a high power conversion efficiency of 16.47 % as well as largely increased stability. This provides a feasible method for large‐scale production of MoS 2 for wide applications in various electric devices.
