 Select Review of fabrication methods of large-area transparent graphene electrodes for industry Petri MUSTONEN, David M. A. MACKENZIE, Harri LIPSANEN Front. Optoelectron..  2020, 13 (2): 91-113.   https://doi.org/10.1007/s12200-020-1011-5 Abstract   HTML   PDF (837KB) Graphene is a two-dimensional material showing excellent properties for utilization in transparent electrodes; it has low sheet resistance, high optical transmission and is flexible. Whereas the most common transparent electrode material, tin-doped indium-oxide (ITO) is brittle, less transparent and expensive, which limit its compatibility in flexible electronics as well as in low-cost devices. Here we review two large-area fabrication methods for graphene based transparent electrodes for industry: liquid exfoliation and low-pressure chemical vapor deposition (CVD). We discuss the basic methodologies behind the technologies with an emphasis on optical and electrical properties of recent results. State-of-the-art methods for liquid exfoliation have as a figure of merit an electrical and optical conductivity ratio of $43.5$, slightly over the minimum required for industry of $35$, while CVD reaches as high as $419$.
