Description
Technical field
The present invention relates to DSSC technical field, be specifically related to a kind of method that full silk screen printing makes dye-sensitized cell (DSSC).
Background technology
DSSC (DSSC), the relatively advantage such as simple manufacture craft low, nontoxic with its abundant raw materials, cost, has attracted the extensive concern of educational circles, industrial circle.Its working mechanism and Mathematical Modeling are just furtherd investigate from that time, comprise electron injection, diffusion and multiple mechanism, and the physical model of whole solar cell.
have employed porous titanium dioxide thin-film, considerably increase the specific area of electrode and the ability of absorbing dye, through with after the bipyridyl ruthenium class dye sensitization of carboxyl, the maximum extinction efficiency of single wavelength can reach more than 98%, and the depth & wideth of DSSC research achieves breakthrough at this point.
Photoelectric efficiency at present based on the small size dye-sensitized cell of titanium deoxid film reaches 13%.But see with regard to the large-area efficiency of DSSC, stability, technical merit, industrialization, scale be realized, also there is the problems such as photoelectric conversion efficiency is not high, secular instability, complex process.
At present, TiO
2be most widely used smooth anode material in DSSC, other broad stopband oxide semiconductor materials are as ZnO, SnO in addition
2, Nb
2o
5deng also under study for action, but with TiO
2combination property best.Due to TiO
2abundance is cheap, nontoxic to be easy to absorbing dye and to become preferred material in dye-sensitized cell.TiO
2the porosity, specific area, particle size, crystal formation, degree of crystallinity etc. of film directly will have influence on Dye Adsorption, electric conductivity, extinction efficiency, the light scattering property of DSSC, thus affect the photoelectric conversion efficiency of DSSC.TiO
2layer must have specific area large as far as possible to adsorb more dye molecule promoting short circuit current to improve dyestuff to the absorption of light.Large specific area adds electron recombination probability simultaneously, and dark current increases.Both is conflict body, needs to reach optimum performance by process optimization.
The preparation method of nano-titanium dioxide film generally comprises Physical and the large class of chemical method two.Physical mainly comprises sputtering method, using vaporization condensation process and molecular beam epitaxy etc.The method preparing nano thin-film mainly chemical method conventional in DSSC research, common chemical method has sol-gel process (Sol-Gel method), predecessor crystalline solid is sublimed into embrane method, electrodeposition process, chemical vapour deposition technique, liquid phase deposition and hydro thermal method etc., and the existence form different according to reactant can be divided into vapor phase method, solid phase method and liquid phase method again.Vapor phase method can control particle size and the shape of product; Solid phase method prepares nano thin-film by the method such as pyrolysis, powdered reaction.Maximum methods is adopted to be liquid phase method, comprising solvent evaporated method, the precipitation method and sol-gel method etc. in current DSSC preparation.
Being prepared in the production of DSSC of titanium dioxide photo anode is a very crucial step, and the pattern of titanium dioxide and character will be directly connected to the photoelectric conversion efficiency of battery.At present conventional sol-gel process constant temperature a period of time and simultaneously add the growth that nitric acid or acetic acid suppresses titanium dioxide, then as hydro-thermal reaction in reactor at a certain temperature.The dispergation of this process need long period, carries out hydro-thermal reaction afterwards, occupies the plenty of time, and condition is not easy to control, and the performance of end product is not good, affects the application of DSSC.
Affecting a lot of because have of DSSC light conversion efficiency, except above-mentioned light anode, also having electrode, dye sensitizing agent, the preparation of redox electrolytes matter and the encapsulation etc. of battery.In traditional DSSC, light anode and to electrode between use liquid electrolyte, but its sealing and electrolyte inject be still a challenge.Usually, sarin film, a kind of hot melt diaphragm seal, is used as the encapsulant assembling battery.Electro-conductive glass bores two or more holes, liquid electrolyte to be filled in battery and to be sealed by epoxy resin with to electrode.Particularly along with the increase of area and the increase of module number, this problem becomes more complicated.
For overcoming liquid electrolyte easy-to-leak liquid and the low inferior weak point of solid electrolyte photoelectric conversion efficiency, people just propose this half-way house of quasi-solid electrolyte.Quasi-solid electrolyte is referred to be strapped in by liquid electrolyte drop in the three-dimensional crosslinked network that gel formed by the method for physics or chemistry and solidifies obtained gel state electrolyte, therefore is usually also referred to as gel electrolyte.The deficiency that quasi-solid electrolyte had not only had the ion mobility similar to liquid electrolyte but also overcome liquid electrolyte prevents the leakage of liquid electrolyte, reduce the vapour pressure of organic solvent, slow down the volatilization of organic solvent, thus improve useful life of dye-sensitized solar cells, therefore obtain and study very widely.In quasi-solid electrolyte, normally used gel has Low Molecular-Weight Gel agent, high molecular polymer gel and nano particle gel etc.
To electrode also known as photocathode.At light anode I
-reduced by the dye molecule of oxidation state, self changes I into
3 -, I
3 -ion is by diffusive migration to photocathode, and the electronics on photocathode is combined and is reduced to I
-be diffused into light anode again and participate in reaction, complete circulation.I
3 -/ I
-regeneration rate have appreciable impact to photronic performance, so to electrode in dye-sensitized cell except needing except good electronic conduction ability as electric negative electrode, another important effect is catalytic action, requires there is catalytic activity high as far as possible to electrode material, accelerates I
3 -/ I
-the switching rate of ion promotes the opto-electronic conversion performance of sensitized cells.Conventional base material does not have above-mentioned performance, experiment shows, simple fluoridizes electro-conductive glass as the photronic performance very low (fill factor, curve factor and photoelectric conversion efficiency are only 6% and 0.02% respectively) to electrode, therefore must modify substrate material surface, form one deck Catalytic Layer at conductive glass surface.
Pt is the material that current catalytic efficiency is the highest, and in experiment, the normal transparent conducting glass of platinum plating that uses is as to electrode.When photocell adopts incident light from the mode of light anode incidence, the Pt layer of light as reflector, can also promote photoelectric conversion efficiency.But be unfavorable for that large-scale promotion uses because Pt resource-constrained is expensive, researchers are just striving to find other suitable material and are carrying out alternative Pt.Material with carbon element enjoys favor and becomes the focus of research because abundance is with low cost, stable chemical nature, catalytic activity are high, have good development prospect.What current report was more is used as to mainly contain graphite, carbon black, carbon nano-tube, activated carbon etc. to the form of the carbon-based material of electrode.The adhesion of the glass of carbon nano-tube and conduction high polymer and conduction is more weak, is unfavorable for photronic long-time stability.Catalytic center due to material with carbon element is positioned on the border of material, and the carbon black material that therefore degree of crystallinity is low, specific area is large has higher catalytic activity than material with carbon element such as graphite, the carbon nano-tube of high-sequential.
The present invention utilizes screen printing technique, instead of the process of other complexity, manufactures DSSC.Screen printing technique is easy to realize a large amount of production, and do not require the production equipment of any costliness.Sinter alternative sarin film with glass dust preparation slurry again through silk screen printing; On dye coating, silk screen printing is by the formulated slurry of gel, pore creating material and liquid electrolyte, heating, forms quasi-solid electrolyte layer; Will by the silk screen printing of carbon black slurry on quasi-solid electrolyte layer, volatilization film forming, shape paired electrode.In addition, be only that carbon black does not need another block electro-conductive glass by silk screen printing on electrolyte to electrode, this will reduce costs to a great extent.
