Implementation of an alternative graphene-based electrode

Here, it is presented the fabrication of a low-cost and semitransparent three-layer graphene electrode (anode) based on an easily processable graphene derivative and the conductive polymer PH1000 (PEDOT:PSS). The graphene derivative was mechanically synthesized and suspended in water (SPGSW); its deposit was made directly by drop casting on a glass substrate. The multilayer nature of the SPGSW films was corroborated by Raman spectroscopy and a number of similar to 7 graphene layers were estimated for the SPGSW film treated with hydroiodic acid (HI) and UV-ozone plasma, which was also corroborated theoretically (similar to 6 graphene layers). Furthermore, for the SPGSW film, a thickness of similar to 5 nm was determined experimentally. The alternative three-layer graphene electrode showed a transmittance and an electrical resistance of similar to 78% (at 550 nm) and similar to 88 omega/sq, respectively. These results are promising for this alternative electrode based on the graphene derivative and for potential application in photovoltaic devices beside other uses.
