Abstract

The invention discloses a method for preparing a stable transparent electrode provided with a neutral PEDOT/PSS conducting layer. The transparent electrode comprises a transparent base material layer and the conducting layer covering the transparent base material layer, wherein the conducting layer comprises a coated first silver nanowire conducting layer part and a second neutral PEDOT/PSS macromolecule conducting layer part or a macromolecule conducting layer part formed by mixing neutral PEDOT/PSS with silver nanowires, and the PEDOT/PSS macromolecule conducting layer part is made of neutral PEDOT/PSS conductive ink. The preparing method comprises the steps that 3,4-EDOT is polymerized into PEDOT/PSS dispersion liquid in the presence of PSS, alkaline additives are added to regulate the PH, neutral PEDOT/PSS dispersion liquid is obtained after the ink strength is high enough through the seasoning technology, and at least one kind of organic functional auxiliaries is added to the neutral PEDOT/PSS dispersion liquid to obtain the stable transparent electrode. The transparent electrode prepared with the method has the advantages of being high in conductivity, high in light permeability, simple in preparing technology, resistant to weather and current stability and the like and can be applied to the fields such as organic solar cells, organic light emitting diodes and touch display screens.

Description

technical field [0001] The invention relates to an optoelectronic component, in particular to a stable transparent electrode with a neutralized PEDOT / PSS conductive layer and a preparation method thereof, belonging to the field of organic optoelectronic technology materials. Background technique [0002] As a conductive and transparent functional material, transparent electrodes have been widely used in related technologies such as thin-film solar cells, flat panel displays, touch screens, PDP displays, OLED displays, and e-books. The general requirements for transparent electrodes are as low as possible sheet resistance, as high as possible light transmittance, and as simple a manufacturing process as possible to keep production costs as low as possible. [0003] Among the existing transparent electrodes, indium tin oxide ITO thin films have been widely used in the above-mentioned fields of components and devices due to their good light transmittance and high electrical con...
