Summary It is well recognized that combining nonpotable water with solar energy to desalinate water and produce water vapor is an effective route to solve the shortage of fresh water. However, the solar vapor generation suffers from either low solar energy efficiency or complex and high‐cost devices. Herein, we explore a black membrane based on polypyrrole (PPy) and filter paper to enhance solar‐to‐vapor conversion performance, thus providing a low‐cost, stable, and strong efficient solar vapor generator. This device displays high solar‐to‐vapor conversion efficiencies of up to approximately 92.2% and 95.6% under irradiation of 1 and 4 kW m −2 , respectively. Therefore, this paper‐based high solar‐to‐vapor conversion and scalable evaporator provides a promising solution to the problem of freshwater scarcity and nonrenewable recourses.
