A perylene diimide (PDI) derivative bearing four chlorine substituents in the bay area is deposited together with pristine multiwall carbon nanotubes (MWNTs) and/or Nafion p ‐ doped MWNTs (p‐MWNTs) onto indium tin oxide (ITO) solid substrates by means of air‐brushing. The resulting photoanodes are studied in photoelectrochemical cells and reveal highest photocurrent efficiencies when PDI and p ‐ MWNT are combined as photoactive materials, indicating the beneficial effect of Nafion.
