Fibrous photo-active compound solar cell and preparation method thereof

Abstract

The invention discloses a fibrous photo-active compound solar cell and a preparation method thereof. The method comprises the following specific steps: (1) selecting a fine copper wire as a conductive electrode; (2) preparing a working electrode through an electrochemical anodic oxidation method, wherein the step (2) comprises the processes as follows: with a titanium wire as an anode and a platinum wire as a cathode, an electrolyte is a glycol water solution containing ammonium fluoride with the mass fraction of 0.2%-0.4% and water with the volume fraction of 4%-6%; the anodic oxidation voltage is 40V to 60V; the anodic oxidation time is 10-30 minutes; and an oriented titania nanotube array which is 1-7 microns in height grows on the surface of the titanium wire; and (3) cleaning the titanium wire which is subjected to anodic oxidation with deionized water for a plurality of times, drying and heating the titanium wire to 450-550 DEG C, keeping the temperature at 450-550 DEG C for 1-3 hours, and naturally cooling the titanium wire, so as to obtain anatase crystal TiO2, immersing the anatase crystal TiO2 into an N,N-dimethyl formamide solution containing porphyrin for 2-4 hours, taking out and drying the anatase crystal TiO2, immersing the anatase crystal TiO2 into a PEDOT:PSS water solution containing thionyl chloride with the mass fraction of 5%-15% for 3-5 minutes, taking out and drying the anatase crystal TiO2, and convolving the anatase crystal TiO2 and a fine copper wire, so as to obtain the product.

Description

technical field [0001] The invention relates to a solar cell and a preparation method thereof, in particular to a fibrous photoactive porphyrin compound solar cell and a preparation method thereof, belonging to the field of organic solar cells. Background technique [0002] As a form of utilizing solar energy, solar cells have received widespread attention. There are many types of solar cells, among which fibrous organic solar cells have attracted extensive attention because of their light weight, flexibility, and weavable properties. At present, dye-sensitized solar cells have been studied a lot, and some progress has been made, but dye-sensitized solar cells need to add electrolyte, which undoubtedly complicates the manufacture of batteries, increases costs, reduces safety and stability, and limits its application. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and the purpose is...
