Water‐soluble CuPc derivatives (TS‐CuPc) have a self‐assembly phase when present with PEDOT:PSS. In particular, a unique nano‐mesh structure is formed in a thin film in which PEDOT:PSS and TS‐CuPc are blended at a specific volume ratio. The nano‐mesh structured thin film can be used as a hole transport layer of perovskite solar cell, and the efficiency of the device applied has increased efficiency and stability compared to the device to which pristine TS‐CuPc or PEDOT:PSS films are applied. The cover figure shows the molecules of TS‐CuPc that are aligned in the presence of PEDOT:PSS and the resulting mesh structure.
