Problems solved by technology

But above-mentioned two patent technologies all adopt photolithography method and etching process to engrave and make the mesh crack mold of metal mesh electrode, not only cost height, process complexity, efficiency are low (for example need to process and prepare the mask of metal mesh membrane plate, and the higher the resolution of the metal grid, the more complex the required process); and when preparing a large-area metal grid, the required process conditions are more complicated, and the performance requirements and production costs of the hardware facilities are also higher. higher

Embodiment 1

[0022] This embodiment takes the preparation method of the composite transparent electrode of graphene film and gold metal mesh as an example:

[0023] Step 1: Preparation of egg white gel: After separating the egg white from the egg yolk, put the egg white and 1 / 3 of the water of the egg white volume together in a miniature magnetic stirrer, and stir until uniform at 500r / min. Get egg white gel, set aside;

[0024]Step 2: Prepare a sheet body with a network crack film sacrificial layer: first clean and dry the polyethylene terephthalate (PET) substrate, and then evenly coat the egg white gel prepared in step 1 Brush it on the substrate, then send it into an oven and heat and bake it at 60°C until the egg white gel on the substrate forms a film with a network crack with a thickness of 2 μm, thereby making a network crack PET sheet of film sacrificial layer;

[0025] Step 3. Preparation of the metal mesh electrode: use the sacrificial layer of the adhesive film with reticular...

Abstract

The invention belongs to the method of producing transparent electrodes by compounding graphene film and metal mesh, including: the preparation of egg white gel, the preparation of sheet body with mesh-shaped crack rubber mold sacrificial layer, the preparation of metal mesh electrode, the preparation of graphene film, Preparation of composite transparent electrodes. The invention uses egg white gel as the mesh crack mold and sacrificial layer of the metal mesh electrode, and then uses magnetron sputtering or vacuum evaporation to make the metal mesh electrode in the composite electrode, and then the metal mesh electrode and the transparent insulation The substrate is covered with a layer of graphene film, and the square resistance of the formed composite transparent electrode is 25-30Ω / sq, and the light transmittance is 90-92%. Therefore, while simplifying the production process and improving the photoelectric characteristics and productivity of the composite electrode, The production cost of the composite electrode is effectively reduced, and it can be widely used in optoelectronic devices such as organic solar cells, organic light-emitting diodes, and touch screens, and can prepare large-area, high-quality composite transparent electrodes and the like.

Description

technical field [0001] The invention belongs to the production method of photoelectric devices in the field of nanoelectronics, in particular to a production method of a transparent electrode with higher light transmittance which is formed by compounding graphene film and metal mesh. Background technique [0002] High-performance transparent electrodes are essential in many optoelectronic devices, such as touch screens, photovoltaic cells, organic light-emitting diodes, etc. Currently commercially, indium tin oxide (ITO) thin films have been widely used in various optoelectronic devices as transparent electrodes due to their high optical transmittance, low surface resistance and mature manufacturing process. However, indium is a rare metal, and its distribution in the earth's crust is relatively small and scattered. It mainly exists in cassiterite and sphalerite in trace amounts. With the popularity of products such as liquid crystal displays and touch screens, the price of ...
