Description
Technical field
Present disclosure generally relates to a kind of jet printing appts, a kind of jet printing appts being applicable to DSSC processing procedure.
Background technology
For solving global energy crisis and reducing environmental pollution; the solaode that solar radiant energy can be converted directly into electric energy is the new problem of actively innovation research and development in recent years; wherein; dye-sensitized solar cells (DyeSensitizedSolarCell; it is called for short DSSC) it is belonging to the organic photovoltaic cell of the third generation, there is the characteristic that low cost is close with silicon-film solar-cell energy conversion efficiency.Compared to traditional list (many) crystal silicons or non-crystal silicon solar cell, cost of material selected by DSSC is low, plus processing procedure easily with simple process apparatus, solar cell power generation cost can be effectively reduced, commercialization is expanded and has sizable benefiting, and because it is not affected by sun angles, plus absorbing, the light time is long, and therefore the generated energy in the identical time more can be better than traditional silicon wafer solaode.In short, dye-sensitized solar cells has large area, light-permeable, low cost, efficiency is high, make simple and plasticity advantages of higher, thus there is great development potentiality, the main flow of future new era solar battery technology development can be become.
The basic start principle of solaode is the motion aggravation of Cucumber its electronics when being irradiated by light；If guiding these electronics to flow through the current potential in a circuit, i.e. can get electric energy.And the Basic Design of DSSC is the granule with the metal-oxide semiconductor (MOS) of nm size, chemically makes its surface adsorption dye molecule, more this granule is coated on the anode of battery circuit as photosensitive layer；And between photosensitive layer and negative electrode, add last layer electrolyte help conduction.
The structure system of known dye-sensitized solar cells 1 is as shown in Figure 1, mainly it is made up of anode 10, electrolyte layers 15 between negative electrode 11 and two electrodes, wherein, anode 10 includes electrically-conductive backing plate 12, can be such as the transparent conductive substrate such as glass or film substrate, the semiconductor film 13 that is arranged on electrically-conductive backing plate 12 and dye coating 14, wherein semiconductor film 13 is generally by titanium dioxide (TiO2) nanoparticle constituted, and have electronics conduction function；Negative electrode 11 has transparent electrically-conductive backing plate 12 ' equally, and it is arranged with nesa coating 16 at electrically-conductive backing plate 12 ', this nesa coating 16 is to be formed by the conductive material of platinum catalyst, then can be formed by redox electrolytes liquid as the electrolyte layers 15 arranged between electrodes.
Dye coating 14 in known dye sensitization solar cell 1 mainly uses the photosensitizer of high efficiency, high stability, such as: ruthenium misfit thing dyestuff (N3, N719 or its related derivatives), in general, the processing procedure of its anode 10 mainly first will be containing titanium dioxide (TiO2) nanoparticle slurry by coating in the way of be formed on electrically-conductive backing plate 12, and through dried, to form it into semiconductor film 13, thereafter, again this electrically-conductive backing plate 12 with semiconductor film 13 is dipped in ruthenium misfit thing dye solution so that it is in titanium dioxide (TiO2) nanoparticle surface adsorption dyestuff, and then on semiconductor film 13, form dye coating 14.
In the processing procedure of this dye-sensitized solar cells 1, large area anode coating process is benefited quite big for dye-sensitized solar cells commercialization, and has become the technology that development dye-sensitized solar cells is indispensable now.Only, anode coating process generally individually uses the such as coating process such as scraper for coating, rotary coating or screen painting at present, but aforementioned no matter which kind of coating process, all cannot be precisely controlled the coating thickness of its coating, and according to the mode of screen painting, more need to again make a plate for different plates, be difficult to carry out the most various production.
In view of this, how developing one can large area spray printing semiconductor film and dyestuff, and the jet printing appts being applicable to DSSC processing procedure of its spray printing thickness can be precisely controlled, to improve above-mentioned located by prior art disappearance, problem the most in the urgent need to address.
Summary of the invention
The main object of the present invention, it is to provide a kind of jet printing appts being applicable to DSSC processing procedure, if having in order to solution known dye sensitization solar battery coating process of employing in time manufacturing titanium dioxide electrodes and cannot being precisely controlled coating thickness of its coating and according to product demand difference, then need the most again to make a plate, be unfavorable for the shortcomings such as the most various production.
Another object of the present invention, it is to provide a kind of jet printing appts being applicable to DSSC processing procedure, it is used on electrically-conductive backing plate carry out the spray printing of the water soluble semiconductor solvent containing titanium dioxide nanoparticle, whereby to form the semiconductor film of cellular structure, again through jet printing appts spray printing dye solvent on the semiconductor film of this cellular structure, whereby to carry out the spatterwork of titanium dioxide electrodes in large area, in addition to the spray printing droplet size that can be accurately controlled water soluble semiconductor solvent and dye solvent, more elastic according to the demand of different product can adjust the pattern that its spray printing goes out, and then richer application, and it is beneficial to the most various production.
