Micromesh carbon nanosheet electrodes fabricated by phase-separation of immiscible polymer blends

Abstract

We adopt micromesh structure in carbon nanosheets (M-CNS) fabricated by phase-separation of immiscible polyacrylonitrile/poly(methyl methacrylate) blend precursors to improve their properties as a transparent conductive electrode. The facile approach without any time-consuming patterning processes can improve trade-off between sheet resistance and optical transmittance of conventional CNS. The M-CNS exhibits improved sheet resistance of similar to 50% without compromising optical transmittance, leading to a high power conversion efficiency of similar to 2.07% for M-CNS electrode-based organic photovoltaics.
