Embodiment 1

[0029] The preparation method of the flexible photoanode material is as follows: 7g of zinc powder is placed in a test tube with an open end, and the titanium sheet that has been corroded by hydrofluoric acid and polished by sandpaper is also placed in the test tube. The distance between the zinc powder and the titanium sheet is 2cm Then the test tube is placed in the quartz tube, and the mixed gas of argon and oxygen is passed into the quartz tube through the gas flow control system, the volume flow of argon is 100 sccm, and the volume flow of oxygen is 0.5 sccm. Heating in a type furnace at a heating rate of 30°C / min. After the temperature rises to 600°C, hold the temperature for 30 minutes, and begin chemical vapor deposition of zinc oxide on the titanium sheet. After holding the heat, it cools with the furnace to obtain a photoanode composed of zinc oxide and titanium sheet P1. The thickness of the photoanode is 160 microns, wherein the thickness of the titanium sheet ...

Abstract

The invention relates to a flexible photoanode material, a preparation method thereof, a device and application of the flexible photoanode material and belongs to the field of nano material preparation and application. The preparation method comprises the step that with a titanium sheet adopted as substrate, zinc powder as a raw material, oxygen as reactant gas and argon as carrier gas, multi-branched nano zinc oxide is deposited on the titanium sheet through a chemical vapor deposition method such that an flexible photoanode consisting of the zinc oxide and the titanium sheet can be obtained. The photoanode can be used for making a flexible dye-sensitized solar cell of which the photoelectric conversion efficiency can achieve more than 3%. The chemical vapor deposition method of the invention is advantageous in pure product, high crystallinity, rapid response, easy and convenient operation and the like, and is a kind of excellent method for preparing a multi-branched zinc oxide nano structure.

Description

technical field [0001] The invention belongs to the field of preparation and application of micro-nano materials, and in particular relates to a flexible photoanode material, a preparation method of the material, equipment used and the application of the material. [0002] Background technique [0003] Flexible dye-sensitized solar cells are a new generation of solar cells after silicon cells and thin film cells. Compared with silicon cells and thin film cells, they have the advantages of low cost, flexibility, simple preparation process, and easy mass production. Flexible dye-sensitized solar cells are usually composed of flexible conductive substrates, semiconductor materials, dyes, and electrolytes, and the electrolytes are not necessary. Titanium is a flexible conductive substrate with excellent performance. When it is used at one end of the photoanode, the titanium dioxide layer formed on its surface can effectively reduce the dark current. Its excellent conductivity c...
