Abstract
Using glass powder being as packaging material, designing special structure of battery plates, the invention packages sensitized battery in sandwich type through low temperature packaging technology. Filling in an amount of inert gases into inside battery to maintain anhydrous, oxygen free, and low-pressure condition, the invention eliminates action of dyestuff and organic electrolyte components to be degraded on surface of TiO2 particles from occurring, as well as solves issue that solar battery performance and efficiency is attenuated and lowed caused by heat induced expansion of liquid electrolyte, volatilization and leakage. Thus, the invention prolongs working life of dyestuff sensitized Nano crystal battery observably, and reduces cost for producing the kind of battery greatly. Also, the invention eliminates environmental pollution issue caused by leaky electrolyte.
Description
Technical field
The anti-ageing packaging method of dye-sensitized solar cells of the present invention belongs to regenerative resource, photocatalysis, chemistry and environmental protection technical field.Especially use special cell panel packaging technology, with vacuum, cold encapsulation means, the organic components such as dyestuff in the realization dye-sensitized cell are not by nano-TiO
2The particle photocatalytic degradation, utilize the inside and outside saturated vapor pressure reduction principle of battery, eliminate the factors such as contaminated environment, battery efficiency decline even damage that electrolyte expands because of thermic and the volatilization leakage causes, and then reach the working life that prolongs battery, reduce the production cost of battery significantly.
Technical background
Along with the fast development of global economic integration, energy problem more and more becomes the problem that national governments and pillar industry need think better of.Energy problem is related to the sustainable development in the whole world, will become the key factor of restriction social development.Along with fossil resources such as oil, coal and natural gas face exhaustion and environment severe exacerbation, regenerative resource industries such as development solar energy, wind energy are then imperative.
With at present on market in the highest flight silicon solar cell De Ang Expensive production cost and complicated preparation procedure compare, the most attracting characteristics of DSSC (dye-sensitized Solar Cell is called for short DSC) are its cheap raw material and relative simply manufacture craft.Since 2001, along with the dye sensitization continuous advancement in technology, this battery industry process is accelerated suddenly in worldwide.Because China is a labor-intensive country, labor cost under Chinese so at present national conditions, is more suitable for its large-scale application well below the input cost of capital and technology.
1993, Gr
Tzel seminar has realized the photovoltaic energy conversion rate of dye-sensitized nano solar cell 10%.At present, the highest transformation efficiency of dye-sensitized cell surpasses 11%.And the solar cell of occuping market leading position is the polycrystal silicon cell of conversion ratio about 14% at present; The amorphous silicon membrane battery of extremely pursuing in recent years, the efficient of its large-scale production are also only just 8%, and the long-term working stability problem that the light fatigue effect of amorphous silicon battery causes is effectively overcome always.Dye-sensitized cell mainly contains three parts and forms: 1. the nano-TiO of surface adsorption dyestuff
2The thin film work utmost point; 2. electrolyte; 3. to the utmost point.Its cost of manufacture and technology are far superior to silion cell.Large-scale production, cost will be less than 1/5 of silion cell.2004, HIT has showed the large size panel of DSSC in the nanometer technology exhibition " NanoTech 2004 " that Tokyo BigSight International Conference and Exhibition Center is held, what show is the battery component that the battery panel that 4 every limits are about 10cm is coupled together.The data that draw in the photoelectric conversion efficiency test that the said firm declares to carry out in the laboratory are 9.3%.This is the peak efficiency of the area battery of present report.But the working life problem of sensitization battery fails to be well solved always.
The parts that are used to absorb sunlight in the dye-sensitized cell are the TiO that adsorbed dyestuff
2Nano-crystal film, this tunic also are the most important parts of battery, and the best dyestuff of the efficient of exploitation mainly is the second bipyridine carboxylic acids complex dye of Ru, and wherein, the electricity conversion of N3, N719 and three kinds of dyestuffs of black dye has all surpassed 10%.In the recent period, pure organic dyestuff development is rapid, and a kind of indoline carboxylic acid dyestuff (indoline dye code name D149) is used for the sensitization battery, and electricity conversion has reached 9.03%.Under irradiation of sunlight, dyestuff is subjected to optical excitation, and electronics transits to excitation state from excite state, because TiO
2The conduction band position of semi-conducting material is lower than the position of dyestuff excitation state, and electronics is injected into TiO from dyestuff excitation state
2Conduction band, pass through external circuit again, electronics is from TiO
2Lead away.But, in whole photoelectric conversion process, also have another one TiO
2The reaction of organic component in light degradation mineralising dyestuff and the electrolyte.TiO
2Being not only a kind of good opto-electronic conversion semi-conducting material, simultaneously also is a kind of catalysis material of good photocatalysis to degrade organic matter.Under solar light irradiation, nano-TiO
2Semi-conducting material produces light induced electron and photohole under the activation of sunlight medium ultraviolet light, electronics separates and move to the diverse location of particle surface with the hole, electronics be adsorbed on nano-TiO
2O on the particle surface
2Generate ultra-oxygen anion free radical O
2 -, hole and H
2The O reaction generates the OH hydroxyl free radical, O
2 -With OH very high oxidizability is arranged all, nearly all organic substance is decomposed, final mineralising becomes CO
2Deng organic molecule, thereby play the effect of sterilization, mildew-resistant, air cleaning, but at dye sensitization TiO
2In the nano-crystalline solar battery, TiO
2This degraded mineralising organic substance performance become adverse factors the most, it also is degraded to micromolecular process at the dyestuff and the organic component in the electrolyte that are carrying out being adsorbed in the surface simultaneously when the solar energy that dyestuff is absorbed is converted into electric energy.This shows, as long as inside battery has O
2Perhaps H
2The existence of O, photoelectric conversion process and light degradation mineralising are inevitable to be taken place simultaneously.Yet to reduce the influence to battery efficiency will all be fatefulue in the loss of any component in the battery, dye-sensitized cell especially, and organic components such as dyestuff are its indispensable most important component.
The another one greatest factor that influences sensitization battery long-time stability is that electrolytical thermic volatilization is leaked.At present mainly concentrate on exploitation new ionic liquid electrolyte, quasi-solid electrolyte and three aspects of solid electrolyte in the research work that overcomes aspect the electrolyte leakage.Ionic liquid is the bigger organism of molecule amount, have less saturated vapour pressure, the volatilization little, have better chemical stability, but its viscosity far above liquid electrolyte, I
3 -Be diffused into the speed on the electrode slowly, the mass transport process is occupied an leading position, thereby has reduced the efficient of battery.Ionic liquid battery peak efficiency is 7.5% at present, much smaller than liquid electrolyte 11%.Quasi-solid electrolyte mainly is to add the gel system in organic solvent or ionic liquid, thereby increase the stability of system, though the efficient of quasi-solid electrolyte has reached 7% at present, but the existence of organic solvent still fails to eliminate fully the influencing factor that volatilization is leaked, and quasi-solid electrolyte exists also that viscosity is big, diffusion is slow, to TiO
2The perforated membrane infiltration is poor, influences the shortcoming of battery efficiency.All solid state electrolyte is big except viscosity, diffusion is slow, the poor permeability, also have the fast shortcoming of crystallization rate.At present, peak efficiency only 3.8%.Organic solvent electrolyte viscosity is low, ions diffusion is fast, component is easily regulated, to nano-TiO
2The advantage of perforated membrane good penetrability.Mainly include machine solvent, oxidation-reduction pair and organic molecule class additive three parts and form, at present, by acetonitrile, I
2/ I
3 -, the electrolyte formed such as tert .-butylpyridine, its battery efficiency surpasses 11%, is higher than other type electrolyte far away, and with low cost.But the organic solvent saturated vapour pressure in the electrolyte is very low, volatilizees fast, leaks under solar light irradiation, has reduced the electricity conversion of battery on the one hand, has also polluted environment on the other hand.
Low temperature, Vacuum Package and inert gas shielding technology are adopted in invention, even make organic components such as dye well electrolyte in the dye-sensitized cell under the long-time irradiation of sunlight, also not by TiO

2Insulation is isolated between band and the band; With another piece conductive glass plate printing H
2PtCl
6Solution becomes band, and 350 ± 25 ℃ of sintering prepare nano metal Pt stratum granulosum, print corresponding photoetching packaging plastic then, and conductive strips are isolated into the banded work electrode plate that constitutes;
With the above-mentioned dye sensitization TiO for preparing
2Battery lead plate with handled well overlapping to electrode glass sheet, be packaged into the sandwich-type cell panel of hollow.Sandwich-type cell panel to encapsulation is reserved aspirating hole.After vacuumizing, inject liquid electrolyte with the mode of pin hole injection, wherein, electrolyte preparation and preservation are to carry out under the anhydrous condition of strictness.Control electrolytical injection rate, guarantee between the cell panel interlayer that the conducting film part that is etched do not have electrolyte and exist.This vacuum condition injects electrolyte down, can strengthen electrolytical filling effect, increases the fill factor, curve factor of solar cell.
The material that is used to encapsulate is a glass dust.The concrete steps of encapsulation are: spray the oxy arc melten glass powder of high temperature with double glazing unit edge welded seal with the oxy arc spray gun.Utilize special sealing device can guarantee the fusion of cell panel localized hyperthermia, dye sensitization TiO
2The thin layer portion temperature remains at below 200 ℃, and dyestuff thermal decomposition can not take place.
Mode with the melten glass powder encapsulates, and has both guaranteed the sealing of encapsulated result, has guaranteed that again thermal decomposition does not take place dye molecule.
After injecting liquid electrolyte, charge into an amount of inert gas from air inlet, as nitrogen, argon gas etc., the pressure of control inside battery is about 0.5～0.8 atmospheric pressure.So just can guarantee that even under higher temperature, electrolyte also can not cause the damage of cell panel because of thermal expansion; Again since the pressure of inside battery less than external pressure, therefore, phenomenons such as volatilization and liquid leakage can not take place in electrolyte yet.
Particularly:
1. will be used to print TiO
2The electro-conductive glass of film is not before also printing, and at conductive layer surface printing or spraying one deck organic protective film (corrosion inhibitor) of electro-conductive glass, (back gauge is 1.5 centimetres on one side with certain position around the electro-conductive glass as required; Each 0.5 centimetre of other three limit back gauge) organic protective film also can be removed with the method for machinery; again this electro-conductive glass being put into the acid corrosion agent soaks; after a few hours; exposed conductive layer is dissolved by the acid corrosion agent; take out conductive glass plate at last and remove organic protective film; and hit exactly on one side and bore an aperture at the be corroded broad handled of conductive layer, be made into the valve hole that can carry out pin injecting gas and liquid.
2. packaged double glazing cell panel is vacuumized from air inlet position with mechanical pump in 150 ℃ drying box, guarantee that vacuum degree reaches 1 * 10
-2Pa.The cell panel of having taken out vacuum is charged into dry inert gas (high-purity N 2 or high-purity Ar) with the pin type aeration reach 1 atmospheric pressure, charge into inert gas after vacuumizing again, repeat in this way 3 times, reach 1 * 10 at last
-2The vacuum degree of Pa.This step mainly is the O that removes in the cell panel
2And H
2O, inside battery does not have O
2And H
2Under the condition of O, TiO
2Perforated membrane when being subjected to UV-irradiation, nano-TiO
2Particle surface then can not produce strong oxidizing property ultra-oxygen anion free radical O
2 -With hydroxyl radical free radical OH, thereby can not produce oxidative degradation, reach the purpose that increases the battery long-term stable operation the organic component in dyestuff and the electrolyte.
3. the cell panel of step 2 is carried out the injection of electrolyte, the method for employing also is the pin type injection method.The injection rate of control electrolyte makes TiO
2Soaked into fully, and do not had TiO around the cell panel
2The place have only the existence of a small amount of electrolyte.The pin type injection method is controlled the sealing of injection rate and cell panel easily.Vacuum condition injects electrolyte down, has also increased electrolyte to dye sensitization TiO
2The infiltration of perforated membrane can improve compactedness greatly, improves the fill factor, curve factor of battery.On the other hand, because TiO
2Perforated membrane has very high specific surface, and contact with electrolyte and can produce very large surface tension, so electrolyte preferential infiltrating T iO fast when injecting
2Perforated membrane when treating that place that the conductive layer of electro-conductive glass is etched has a small amount of electrolyte to occur, proves TiO
2Perforated membrane is soaked into fully by electrolyte.Cell panel edge conductive layer be etched with two effects, a side gives at inside battery having stayed corresponding vacuum space, makes to be heated electrolyte illumination Shi Buhui leaks because of the thermic volatilization and expansion causes the battery efficiency decay even damage; On the other hand, the edge conductive layer is etched, and situation about being short-circuited between two battery lead plates appears also can not taking place in electrolyte at the cell panel edge because of thermal expansion and volatilization.
4 cell panels that step 3 is obtained carry out an amount of inert gas (high-purity N again
2Charging into perhaps high-purity Ar), control inside battery pressure is 0.5-0.8 atmospheric pressure, finally sealed obtains being used for the baby battery of splicing large area cell panel.Keeping of pressing in an amount of is necessary, and on the one hand, high vacuum condition is not easy long-term maintenance, O
2And H
2In a single day O enters, and the light degradation mineralising is carried out immediately; On the other hand, inner high vacuum, cell panel is subjected to high external pressure stress and damages easily.
Characteristics of the present invention are: the anti-ageing encapsulation technology of dye-sensitized solar cells is according to TiO
2Nano particle does not generate the hydroxyl radical free radical OH and the superoxide anion free radical O of strong oxidizing property under solar light irradiation in the inert atmosphere of anhydrous, anaerobic
2 -Thereby, dyestuff and organic molecule are not produced the sensitization solar cell encapsulation new technology of photocatalytic Degradation.Finally can effectively stop the decay of cell photoelectric transformation efficiency, extending the life of a cell at double reduces the production cost of sensitization battery significantly.
