Work function of carbon nanosheets (CNSs) is easily controlled using various chloride-based metal precursors. The metal ions in the precursors are reduced despite the simple spin coating without posttreatment due to electron transfer from the CNSs to the ions. The work function of CNSs doped with AuCl3, ZnCl2, and CoCl2 presented values of 4.91, 4.77, and 4.69 eV, respectively, which are significantly higher than pristine CNSs (4.60 eV). The reduced metal nanoparticles locally induced electronic modification of the CNSs located in the vicinity, leading to transparent conducting electrodes with high work functions and subsequently a high power conversion efficiency of ~2.01% for an ITO-free OPV incorporating a AuCl3-doped CNS electrode.
