In article number 1900004, Bi Xu and co‐workers design an easy‐to‐manufacture, low‐cost, and highly reliable solar‐driven evaporator for water purification using a black cotton towel with a hollow conical shape. The reactive dye molecules diffuse into the cotton and form strong covalent bonds with the fiber after dyeing, which firmly fixes light‐absorbing materials on the substrate.
