Abstract

Transparent electrodes, which are widely used in displays and solar cells, are predominately utilized indium tin oxide film (ITO). However, several drawbacks such as high price (limited resources), brittleness and requirement of high vacuum deposition conditions are the driving forces for next generation of electrode development. Currently, the emerging solution is using carbon nanotubes or silver nanowires due to low junction resistance. In fact, nano-structure can effectively reduce the sheet resistance, however, the interface resistances of carbon nanotubes and graphite are desperately to minimize. Moreover, existing technology to grow silver nanowires are limited to 100 aspect ratio (length-to-diameter) as well as relatively expensive material cost. We propose a low-cost and scalable electrospinning process to fabricate metallic nanowire arrays such that high-performance transparent electrode can be obtained. Typically, electrode conductivity (resistance) and transparency are two key factors to be considered for a large scale adoption. Commercially, solar cells and liquid crystal displays are seeking electrode resistance less than 20 Ω /m<SP>2</SP>, to avoid unnecessary voltage drops and additional heat consumption during operation. Traditionally, ITO is widely used in various optoelectronic devices, transparent electrodes, and the increased demand for electronic products in recent years, making the ITO prices skyrocketing in the past decade,. Moreover, the ITO film is brittle and fragile to sustain significant deformation for flexible substrates. The present invention shows a manufacture method for metallic nanowires, aims to replace traditional ITO in terms of high performance and high scalability. This invention includes the followings: (1) the metal salts, solutions and various surfactants are dissolved in a solvent by magnetically stirred, (2) Set substrate plate in a mechanically mobile platform, through the mobile platform to control the nanowire array spacing, (3) applied high voltage using DC power supply and through a needle, nanowires can be electrically stretched and deposited. Furthermore, adjusting high voltage and electric field can effectively control the diameters metal nanowire, (4) calcined thoroughly in air for a period, (5) hydrogen annealing for later testing.

If there is a chemical formula in this case, please reveal the chemical formula that best shows the characteristics of the invention: [Description of the Invention] [Technical Field] The present invention describes a near-field electrospinning technique, in particular, emphasizing near-field electrospinning and controlling metal nanowire spacing, metal nanowire diameter, and metal nanowire stacking height , light transmission ^ and guide [Prior Art] 201226644 Indium tin oxide στο) is a mixture of indium oxide (In2〇3) and tin (IV) oxide (Sn〇2), usually 90% by mass In2 〇3,10% Sn〇2. It is transparent and colorless in the form of a film, but it is yellowish gray in the block state. The main characteristic of indium tin oxide is its combination of electrical, conductive and optical properties. However, compromises are needed in thin failures because high concentrations of charge carriers will increase the conductivity of the material, but will reduce its transparency. Indium tin oxide thin films are most commonly deposited onto the surface by electron beam evaporation, physical vapor deposition, or by some deposition techniques. Because of the high price and limited supply of indium, the lack of brittleness and softness of the IT layer, and the high cost of vacuum, other alternatives are being sought. The solution that has arisen in recent years is to make the carbon nanotubes or silver-nine, because at the junction of low resistance, the structure of the rice can effectively reduce the sheet resistance, but the resistance of the interface between the carbon nanotubes and the graphite is too high; The aspect ratio of the silver nanowire is limited to approaching 1〇〇, and the silver phase is expensive. The following five major losses are caused: (1) The high price of tin oxide, brittleness, and high vacuum deposition are their limitations. (2) High concentration of charm 2 will increase the machine's electrical rotation, but will reduce its transparency. (3) The resistance of the interface between the carbon nanotubes and the graphite is too high; the aspect ratio of the secret is limited to close to 100, and the silver is relatively expensive. (4) It is impossible to accurately control the aspect ratio, pitch, wire diameter, etc. of the metal nanowire. (5) Cannot be applied to flexible boards.
