Description
Technical field
The application belongs to dye-sensitized solar cell anode technical field of material, is directed to a kind of acanthosphere
The environment-friendly preparation method thereof and purposes of shape TiO2.
Technical background
Dye-sensitized solar cells (DSCs) is turned with its cheap cost, simple technique and relatively high photoelectricity
It changes efficiency and has attracted worldwide attention, become one of the solar battery of current most potentiality to be exploited.Dyestuff is quick
Change solar battery to consist of three parts: the nanocrystalline porous light anode of dye sensitization and is loaded with catalysis at redox electrolytes liquid
Agent to electrode.Wherein, developing efficient optical anode material is the key that improve such cell photoelectric transformation efficiency.Efficient light anode
Material usually has biggish specific surface area and quick charge transfer performance.Generally, the light being made of nano-crystalline granule
Anode film often has biggish specific surface area, to guarantee sufficiently large Dye Adsorption amount, promotes light utilization ratio.However it receives
The presence of a large amount of granular boundaries greatly reduces the rate of carrier transport in the brilliant film of rice, increases the probability of charge recombination.
In fact, charge transport properties are highly dependent on the pattern of anode material, compared to nano-crystalline granule, one-dimentional structure is such as received
Mitron, nano wire etc. have biggish charge transport rate, thus construct one-dimensional nano structure become reduce charge transfer resistance,
Increase the effective way of transmission speed.However, effectively overcoming electricity based on the dye-sensitized solar cells of one-dimensional nano structure
While lotus transmission performance, but along with the extreme loss of specific surface area.Thus how to balance efficiency of light absorption and charge transmits
Relationship between performance is universal, the crucial problem of the efficient DSCs of exploitation.
Structure by the lesser structural unit composition micron level of partial size is effective coordination and the above-mentioned two necessary item of balance
One important method of part.Based on such a design philosophy, multiple research teams have been prepared with different-grain diameter
TiO2Microballoon.Due to nanocrystalline as basic unit using small particle TiO2, thus can while large specific surface area is provided
The crystal grain boundary and defect inside spherical structure are reduced to a certain extent.Moreover, the TiO of this three-dimensional2Usually have
Micropore or meso-hole structure, thus get enter into light wave inside light anode, greatly increase light utilization ratio.With commercially use TiO2
(P25) and the TiO of small particle2It compares, the incident photon-to-electron conversion efficiency of the structure is remarkably reinforced.However due to mistake inside the three-dimensional structure
Small basic structural unit partial size also will increase inside configuration charge recombination not only bad for Built-in potential is formed, to limit
The further promotion of battery performance.
Increase the draw ratio of basic unit and provides new Research Thinking to promote the performance of dye-sensitized solar cells.
Basic unit for constructing three-dimensional structure can be nanometer rods, nanometer bundle and nano wire etc..In this configuration, because of 1D structure
Presence and so that electron-transport is accelerated；At the same time, specific surface area can be made by adjusting the size with optimization 1D structure
It is maintained, realizes the active balance of electron-transport and Dye Adsorption.Moreover, light scattering in this hierarchy
It will can also get a promotion.It may be speculated that promote the photoelectric conversion performance of such three-dimensional structure, for basic cell structure
It is most important with the regulation of pattern.Kim etc. synthesizes the three-dimensional TiO of a variety of dendritic structures using hydro-thermal method2, but the research is adopted
It is titanium source with the higher butyl titanate of price, thus increases preparation cost；In addition, in the synthesis process also for control pattern
A variety of organic reagents, i.e. ethylene glycol and cetyl trimethylammonium bromide are additionally added to, expenditure is not only increased and also aggravates
Environmental pressure.
Application number 201510740402.X discloses a kind of flower-shaped TiO2It the preparation method of/graphene photo-catalyst and its answers
With specifically with titanium tetrachloride TiCl4As titanium source, bromo N- butyl-pyridinium ionic liquid passes through water as style control agent
Hot microwave method is prepared.But this method in implementation process only by means of style control agent (bromo N- butyl-pyridinium from
Sub- liquid) under the action of can just obtain flower-shaped TiO2, this undoubtedly increases environmental pressure and cost；In addition, to finally obtain flower
Shape TiO2It also needs by hydro-thermal microwave treatment, and the use of relevant device considerably increases the research cost of product.And it is of the invention
The synthesis technology of involved exploitation controls without any shape or regulates and controls reagent, while without High-temperature water heat treatment.It synthesized
Journey is simpler, economical and environmentally protective.
Up to the present cut-off, still rarely has using three-dimensional dendroid or acanthosphere TiO2Report of the structure as optical anode material
Road, one of them important reason may just be the absence of the important method for synthesizing such material.
