Embodiment Construction

[0031] In describing embodiments of the invention, specific terminology is employed for the sake of clarity. However, it is not intended that the invention be limited to the specific terms so chosen. It is to be understood that each specific element includes all technical equivalents which operate in a similar method to achieve a similar purpose.

[0032] The present invention adopts the composite transparent electrode of graphene / MXene / graphene sandwich structure to replace ITO as the transparent electrode of the flexible photoelectric device, wherein the graphene on both sides is prepared by CVD method, and MXene is prepared by solution synthesis method. Through mechanical transfer of graphene and spin-coating of MXene, a transparent electrode is finally prepared by lamination. The composite transparent electrode with a sandwich structure of the invention solves the problem that MXene is easily oxidized as a transparent electrode.

Abstract

The invention discloses a flexible transparent electrode suitable for a flexible photoelectric device, a battery and a preparation method thereof, and the flexible transparent electrode, the battery and the preparation method use a graphene / MXene / graphene sandwich structure, so that the problem that the conductivity is reduced due to the fact that MXene is oxidized can be effectively avoided. Thegraphene / MXene / graphene composite electrode can simultaneously have the advantages of optics, electricity, mechanical properties, stability, low cost and the like, and can become an excellent flexibletransparent electrode of a flexible photoelectric device.

Description

technical field [0001] The invention belongs to the field of photoelectric devices, and in particular relates to a flexible transparent electrode, a battery and a preparation method suitable for flexible photoelectric devices. Background technique [0002] The transparent electrodes of flexible optoelectronic devices need to meet the following characteristics: high optical transmittance, high electrical conductivity, good mechanical resistance, strong stability, and cheap materials. ITO has good optical and electrical properties, and is the most commonly used TCO material in the field of optoelectronics. However, when ITO is used as an electrode material in flexible devices, it is difficult to obtain satisfactory results. This is because on the one hand, the temperature resistance of flexible substrates such as PET / PEN generally does not exceed 150 °C, and ITO prepared at low temperature There are many defects in the film, and the electrical and optical properties are lost....
