An Ag-grid/graphene hybrid structure for large-scale, transparent, flexible heaters.

Abstract: Recently, carbon materials such as carbon nanotubes and graphene have been proposed as alternatives to indium tin oxide (ITO) for fabricating transparent conducting materials. However, obtaining low sheet resistance and high transmittance of these carbon materials has been challenging due to the intrinsic properties of the materials. In this paper, we introduce highly transparent and flexible conductive films based on a hybrid structure of graphene and an Ag-grid. Electrohydrodynamic (EHD) jet printing was used to produce a micro-scale grid consisting of Ag lines less than 10 μm wide. We were able to directly write the Ag-grid on a large-area graphene/flexible substrate due to the high conductivity of graphene. The hybrid electrode could be fabricated using hot pressing transfer and EHD jet printing in a non-vacuum, maskless, and low-temperature environment. The hybrid electrode offers an effective and simple route for achieving a sheet resistance as low as ∼4 Ω per square with ∼78% optical transmittance. Finally, we demonstrate that transparent flexible heaters based on the hybrid conductive films could be used in a vehicle or a smart window system.

Surface Characterization and Modification of Indium Tin Oxide in Ultrahigh Vacuum

Abstract: Modern organic light emitting diode (OLED) architecture comprises a transparent supporting platform (for example, glass) covered with a thin film of transparent conducting oxide (usually indium tin oxide, ITO) that serves as the device anode. 1-4 The ITO is overlain first with an organic hole-transport layer (HTL) material, then an emissive, electron-transport layer, and finally, a low work function cathode. Photons produced by recombination of carriers escape through the oxide film and the supporting platform.1,5 Commercially available thin film ITO has good conductivity and excellent transparency in the visible region, but it has been suggested that inefficiency of hole injection from ITO can lead to poor device characteristics in OLED applications. 1,6-10

Fully indium-free flexible Ag nanowires/ZnO:F composite transparent conductive electrodes with high haze

Abstract: Solution-processed metal nanowires (NWs) and Earth-abundant doped ZnO have been proposed to replace the most widely used indium tin oxide (ITO) transparent and conductive electrode Generally, there is a dilemma, the trade-off between optical transparency and conductivity for these materials taken alone makes them difficult to compete with commercial ITO In this work, a modified polyol synthesis method was adopted to grow single-crystal silver nanowire with controlled length by adding AgNO3 solution in advance and using high molecular weight polyvinylpyrrolidone (PVP) Ag nanowires ink was then spin coated onto flexible PET substrate to form Ag NW mesh, which shows impressive transparent and conductive (TC) property with sheet resistance of 23 Ω sq−1 and transmittance of 904% at a wavelength of 550 nm A post fluorine-doped ZnO (FZO) layer was then deposited by pulsed laser deposition method to improve the TC, stability and mechanical property High-quality Ag NW/FZO composite electrode was finally acquired at room temperature after optimizing the Ag NW length, concentration in suspension, and FZO layer thickness, with transmittance of 83% at wavelength of 550 nm, sheet resistance of 17 Ω sq−1, and high haze of 365% Perovskite solar cells incorporating such Ag NW/FZO composite electrode exhibited a better cell performance compared to the similar FTO-based perovskite solar cells

Synthesis of Carbon Tubule Nanocoils in High Yield Using Iron-Coated Indium Tin Oxide as Catalyst

Abstract: We have synthesized carbon coils of nanometer-scale size by catalytic thermal chemical vapor deposition. The catalyst used is iron-coated indium tin oxide and the carbon source is acetylene. The yield of carbon coils is over 95% at a growth temperature of 700°C. The carbon coil usually consists of two or more carbon tubules and each of them grows with its own diameter and pitch. The external diameters of the coils are from several tens to several hundreds of nanometers. It is found that iron plays an important role in the growth of carbon nanotubes, while indium, tin, oxygen, and/or their alloys are necessary in the formation of the coils.
