Technical field
The present invention relates to a kind of molybdenum disulfide/titanium carbide/carbon composite nano-fiber film and its preparation method and application, belong to
Flexible solar battery technical field.
Background technology
With the development of science and technology, intelligent textile has been occurred gradually in our visual field, this emerging industry rises abruptly
The progress of human society certainly will will be carried forward vigorously by rising.And the intelligent textile based on battery is one important directions of textile,
It is the key factor for restricting wearable electronic product.Inexhaustible solar energy is converted into the solar cell of electric energy
The favor of numerous researchers is obtained.However, conventional solar cell relative stiffness, meeting how solar cell can
The requirement of wearing turns into the focus of research.
In numerous solar cells, DSSC (Dye-Sensitized Solar Cells, DSSC)
Possess the advantages such as making is simple, material is easy to get, cost is low.Such battery is proposed by professor M.Gratzel since 1991, using tool
There is the nanoporous TiO of high-specific surface area2Instead of traditional plate electrode, about 10 microns of thick optical clear films are formed, then
Dipping dyestuff obtains, and its photoelectric transformation efficiency is up to 7.1%.However, traditional DSSC, due to light anode and to the substrate of electrode all
It is glass, causes battery quality weight, it is frangible, seriously limit its practical application.If it can be made on the high flexibility substrate of lightweight
Standby DSSC, you can obtain high flexibility DSSCs, will be provided with the potentiality being combined with textile, will also be greatly promoted answering for DSSC
With.And the core of high flexibility substrate design is light anode and to electrode, at present, the research of high flexibility light anode is more, and obtains
Certain progress, still, research of the high flexibility to electrode needs further to be strengthened.
It is the important component of DSSC to electrode, it is the electronics for collecting external circuit that it, which is acted on, and
By the I in electrolyte3 -It is reduced to I-.Traditional is typically made up of to electrode platinum plating electro-conductive glass, but alloy platinum material cost is high, long
Phase is using easily by electrolytic corrosion.In recent years, carbon material had good electric conductivity, thermal conductivity, catalytic activity and corrosion resistance
The characteristics of, there is vast potential for future development in the application field to electrode.Therefore, graphene film is thin to electrode, CNT
Film is widely studied to electrode, carbon black film to carbon materials such as electrodes to electrode etc..Although these carbon materials can be effective to electrode
Reduce DSSCs cost, but themselves preparation technology is more complicated, and Yield comparison is low, and with the knot to electrode base board
Close relatively difficult, the stability of battery is also to be improved, thus its practical application is somewhat limited.
In recent years, increasing concern is attracted electrode by the use of the standby carbon nano-fiber of electro-spinning as DSSCs.Such as
Qiao et al. and Lee et al. is respectively by carbon nano-fiber and hollow carbon nanofibres deposit on conducting glass substrate, as right
Application of electrode is in DSCSs.Then, Qiao et al. is by TiO2Nano particle and carbon nano-fiber mixed deposit are in conducting glass substrate
It is upper to be applied to DSSCs.However, because the pure carbon nanofiber membrane low intensity of Static Spinning, fragility are big, it is difficult to combined with flexible substrate,
It is typically only capable to the DSSCs applied to glass substrate.High flexibility how is obtained efficiently to ask electrode as high flexibility DSSC key
One of topic.
The content of the invention
The purpose of the present invention is to be directed to the above-mentioned problems in the prior art, it is proposed that a kind of to have good electro-catalysis

Change on titanium/carbon composite nano-fiber membrane carrier.
Although titanium carbide is added in carbon nanofiber membrane can significantly improve the pliability of carbon nanofiber membrane and certain
Its electro catalytic activity is improved in degree, but its electro catalytic activity is still difficult to match in excellence or beauty with platinum electrode.And molybdenum disulfide is a kind of high
Catalytic activity to electrode material.Therefore, the present invention is by molybdenum disulfide and flexible titanium carbide/carbon composite nano-fiber film combination,
The electro catalytic activity of flexible nano fiber membrane electrode is significantly improved, and then improves flexible DSSCs electricity conversion.
Second purpose of the invention is the preparation side for providing above-mentioned molybdenum disulfide/titanium carbide/carbon composite nano-fiber film
