Description
Technical field
The present invention relates to DSSC technical field, and in particular to it is quick that a kind of full silk-screen printing makes dyestuff
The method of electrochemical cell (DSSC).
Background technology
DSSC (DSSC), so that its abundant raw materials, cost be low, nontoxic, relatively simple making work
The advantages of skill, educational circles, the extensive concern of industrial circle are attracted.Its working mechanism and mathematical modeling are just goed deep into from that time
Research, including electron injection, diffusion and multiple mechanism, and the entirely physical model of solar cell.Employ many
Porous titanium dioxide film, considerably increases the specific surface area of electrode and the ability of absorption dyestuff, through the bipyridyl ruthenium with carboxyl
After class dye sensitization, single wavelength maximum extinction efficiency can reach more than 98%, the depth of DSSC research
Breakthrough is achieved with regard to this with range.
The photoelectric efficiency for being currently based on the small area dye-sensitized cell of titanium deoxid film has reached 13%.But just
Efficiency, stability, the technical merit of DSSC large area are seen, to realize industrialization, scale, also there is photoelectric transformation efficiency not
The problems such as height, secular instability, complex process.
At present, TiO2It is most widely used light anode material in DSSC, other broad stopbands in addition
Oxide semiconductor material such as ZnO, SnO2、Nb2O5Deng also under study for action, but with TiO2Combination property it is optimal.Due to TiO2Come
Source enrich it is cheap, nontoxic be easy to absorption dyestuff and as preferred material in dye-sensitized cell.TiO2The hole of film
Gap rate, specific surface area, particle size, crystal formation, crystallinity etc. by directly influence DSSC Dye Adsorption,
Electric conductivity, extinction efficiency, light scattering property, so as to influence the photoelectric transformation efficiency of DSSC.TiO2Layer
There must be specific surface area as big as possible to adsorb more dye molecules to improve absorption lifting short circuit electricity of the dyestuff to light
Stream.Simultaneously big specific surface area adds electronics recombination probability, dark current increase.Both is conflict body, it is necessary to pass through
Process optimization reaches optimum performance.
The preparation method of nano-titanium dioxide film generally comprises Physical and the major class of chemical method two.Physical mainly includes
Sputtering method, vaporization condensation process and molecular beam epitaxy etc..That is commonly used in DSSC research prepares nano thin-film
Method be mainly chemical method, common chemical method has sol-gel process (Sol-Gel methods), predecessor crystalline solid to be sublimed into
Embrane method, electrodeposition process, chemical vapour deposition technique, liquid phase deposition and hydro-thermal method etc., according to the different existence form of reactant
Vapor phase method, solid phase method and liquid phase method can be divided into again.Vapor phase method can control the particle size and shape of product；Solid phase method is to pass through
The methods such as pyrolysis, powdered reaction prepare nano thin-film.Current DSSC uses most in preparing
Method be liquid phase method, including solvent evaporated method, the precipitation method and sol-gel method etc..
The preparation of titanium dioxide photo anode is a very crucial step in the production of DSSC,
The pattern and property of titanium dioxide will be directly connected to the photoelectric transformation efficiency of battery.Conventional sol-gel process is one at present
Constant temperature at temperature is determined for a period of time while addition nitric acid or acetic acid suppress the growth of titanium dioxide, then as in reactor
Hydro-thermal reaction.The process needs the dispergation of long period, and hydro-thermal reaction is carried out afterwards, occupies the plenty of time, and condition is not allowed
Easy to control, the performance of final product is not good, influences the application of DSSC.
Influence DSSC light conversion efficiency factor have a lot, in addition to above-mentioned light anode, also pair
Electrode, dye sensitizing agent, the preparation of redox electrolyte and encapsulation of battery etc..In traditional DSSC, in light anode and
To using liquid electrolyte between electrode, but its sealing and electrolyte injection is still challenge.Generally, sarin film, it is a kind of
Hot melt diaphragm seal, is used as assembling the encapsulant of battery.Two or more holes are bored on electro-conductive glass, by liquid electrolyte
Matter is filled into battery and is sealed by epoxy resin and to electrode.Increase and module number in particular with area
Increase, this problem becomes increasingly complex.
For the weak point such as overcome liquid electrolyte easy-to-leak liquid and solid electrolyte photoelectric transformation efficiency low, people just carry
Go out quasi-solid electrolyte this half-way house.Quasi-solid electrolyte refers to liquid electrolyte liquid by method physically or chemically
Drop, which is strapped in the three-dimensional crosslinked network of gel formation, solidifies resulting gel state electrolyte, therefore is also generally referred to as gel
Electrolyte.Quasi-solid electrolyte had not only had the ion mobility similar to liquid electrolyte but also had overcome liquid electrolyte not
Foot prevents the leakage of liquid electrolyte, reduces the vapour pressure of organic solvent, slows down the volatilization of organic solvent, so that it is quick to improve dyestuff
Change the service life of solar cell, therefore obtain very extensive research.There is usually used gel in quasi-solid electrolyte
Machine small molecule gel, high molecular polymer gel and nano particle gel etc..
Photocathode is also known as to electrode.In light anode I-The dye molecule of oxidation state is reduced, itself is changed into I3 -, I3 -Ion
By diffusive migration to photocathode, combined with the electronics on photocathode and be reduced to I-Light anode is diffused into again and participates in reaction, is completed
Circulation.I3 -/I-Regeneration rate photronic performance is had a significant impact, so to electrode in dye-sensitized cell except make
Needed for electric negative electrode beyond good electronic conduction ability, another important effect is catalytic action, it is desirable to electrode material
Material has catalytic activity as high as possible, accelerates I3 -/I-The switching rate of ion lifts the opto-electronic conversion performance of sensitized cells.It is conventional
Base material do not have above-mentioned performance, experiment shows, simple fluorination electro-conductive glass is used as the photronic property to electrode
Can be very low (fill factor, curve factor and photoelectric transformation efficiency are only 6% and 0.02% respectively), it is therefore necessary to substrate material surface
Modified, in conductive glass surface one layer of Catalytic Layer of formation.
Pt is current catalytic efficiency highest material, in experiment, often uses the transparent conducting glass of platinum plating as to electrode.
When photocell using incident light from light anode it is incident by the way of when, bright Pt layers are also used as reflecting layer, lifting photoelectricity turn
Change efficiency.But it is due to that the expensive large-scale promotion that is unfavorable for of Pt resource-constraineds is used, researchers are just striving to find other
Suitable material substitutes Pt.Carbon material is because abundance is with low cost, chemical property stable, catalytic activity is high and enjoys green grass or young crops
Look at and turn into the focus of research, with good development prospect.The more shape being used as to the carbon-based material of electrode is reported at present
State mainly has graphite, carbon black, CNT, activated carbon etc..The adhesion of CNT and conduction high polymer and conductive glass
It is weaker, it is unfavorable for photronic long-time stability.Because the catalytic center of carbon material is located on the border of material, therefore crystallinity
The big carbon black material of low, specific surface area has higher catalytic activity than the carbon material such as graphite, CNT of high-sequential.
The present invention utilizes screen printing technique, rather than other complicated processes, to manufacture DSSC.Screen printing technique is
A large amount of productions are easily achieved, and do not require any expensive production equipment.Slurry, which is prepared, with glass dust passes through silk-screen printing
Re-sinter to substitute sarin film；The slurry that silk-screen printing is formulated by gel, pore creating material and liquid electrolyte on dye coating
Material, heating forms quasi-solid electrolyte layer；It will be screen printed onto by carbon black slurry on quasi-solid electrolyte layer, volatilize film forming, shape
Paired electrode.In addition, be only to electrode carbon black by being screen printed onto on electrolyte without another piece of electro-conductive glass, this
Cost will be reduced to a great extent.
