Description
Technical field
The present invention relates to ink for ink-jet printer and preparation method thereof for a kind of flexibility or thin-film solar cells, by using this ink printed on the surface of flexibility or thin-film solar cells incidence surface, directly improve the efficiency of flexibility or thin-film solar cells.And there is self-cleaning effect.
Background technology
Acrylic resin has that look shallow, transparency is high, light is plentiful, it is tough and tensile to film, strong adhesion, the feature such as corrosion-resistant, is conventional coated material.Because acrylic resin exists certain defect in specific occasion, as good not in hardness, resistance to crocking, solvent resistance, mechanical property and high expensive etc., has limited its further application.In recent years, along with constantly improving and development of polymerization technique, and the attention of people to environmentfriendly products, the modification of acrylic resin gets more and more people's extensive concerning.Chinese scholars has been carried out a large amount of deep research, utilizes organic fluorine to carry out modification to acrylic resin, has obtained reasonable effect.
Low surface energy polymeric has unique performance, has in a lot of fields important application, becomes the focus of people's research.The antifouling property of fluoro-containing coating is better, but expensive.The price of organosilicon series coating is lower than fluorine coating, but antifouling property is slightly poor.In view of both, respectively have weak point during separately as antifouling coating, how to utilize both advantages, the low-surface-energy material of developing cost performance excellence is an importance of research.UV-light (UV) curing technology have curing speed fast, pollute the advantages such as little, energy-conservation, cured product excellent performance, be a kind of eco-friendly green technology.In photocuring industry, acrylate quasi-oligomer because of its photocuring reaction activity higher, cured film has good thermotolerance, weathering resistance, and polarity and apolar surfaces are all had to the very strong performances such as sticking power, becomes the main raw material(s) of photocuring industry.
Effectively utilizing in the middle of project of sun power: solar photovoltaic utilization is research field with fastest developing speed in the last few years, most active.The making of general solar cell is mainly to take semiconductor material as basis, opto-electronic conversion reaction generating occurs after utilizing photoelectric material to absorb luminous energy.According to the difference of material therefor, solar cell can be divided into: A, silicon solar cell; The solar cell that B, the inorganic salt of take are material as multi-element compounds such as gallium arsenide III-V compound, Cadmium Sulfide, copper indium diselenide; C, the solar cell of preparing with functional high molecule material; D, nano-crystalline solar battery etc.
The Shi Yi III-V family semiconductor inorganic materials that prior art working efficiency is the highest is raw-material product.For example: the quantum well of the single junction type of gallium arsenide/germanium falls into crystal structure, and its photoelectric transformation efficiency can reach >18 %; For example, and multiple junction quantum well falls into crystal structure solar cell: InGaP/gallium arsenide/germanium, its photoelectric transformation efficiency can be up to >30 %.Most widely used at present, take silicon as main: comprise non-crystalline silicon, photoelectric transformation efficiency approximately 9 %; Polysilicon, photoelectric transformation efficiency approximately 14 %; Silicon single crystal, photoelectric transformation efficiency approximately 17 %.Although in price, elements Si Yao Bi III-V family of VI family semiconductor GaAs is cheap, the price of its manufacture is compared with polymer organic solar batteries, or expensive many; And in application, the light weight again overall plasticization organic solar batteries of the anxiety of crack-free can be realized via the processing of printing, except price reduces, be more suitable for the demand of portable electronic product, and indoor or cloudyly all can normally use (this is that siliceous solar cell is beyond one's reach), its practicality and market application range are promoted more.
Solar cell is a gordian technique, advances more clean Energy production.But the Cost Problems of solar cell, has reduced the economic competitiveness of heliotechnics.For overcoming this problem, thin-film solar cells is the technology of current widespread use, can reduce in a large number the usage quantity of expensive semiconductor material, but the absorbing amount of thin-film solar cells is lower, and Performance Ratio is not gone up traditional solar cell.
Thin-film solar module is by glass substrate, metal level, transparency conducting layer, electrical function box, glueing material, semiconductor layer ... wait formed.Organic and inorganic composite solar battery is the solar cell based on organic conjugate polymer-inorganic nano-crystal composite system, because of while tool organic polymer material good film-forming property, level structure and band gap are easy to regulate, can prepare low cost, big area, flexible solar battery device and inorganic nano-crystal material high stability by wet method, high mobility, can construct the advantages such as ordered nano-structure, and become the study hotspot of area of solar cell in recent years.Metal nanoparticle can direct light enter solar cell better, prevents light escape.In traditional " thick film " solar cell, nanoparticle does not have any effect, because all light absorbs, is all by this film, and this just relies on its thickness.Yet for film, nanoparticle just can be brought into play great role.Their scattering has increased light and has rested on the time in film, makes the light of overall absorption reach a kind of level, and traditional solar cell can match in excellence or beauty.
Aluminium and Nano silver grain are in the frequency spectrum of visible part, and focused ray enters solar cell well.But optical resonance also can cause nanoparticle absorb light, this efficiency that just means solar cell can be lower.Nano grain of silver sub-resonance is just in time in the crucial absorption spectrum part of solar cell, so the absorption of light is appreciable.Aluminum nanoparticles resonance has exceeded the crucial spectra part of solar cell.Loss to energy is less, and in addition, aluminum particulate is easy to passivation, although can change shape and size, after passivation, nanoparticle attribute change is very little.Nanoparticle has rough surface, and scattered beam can enter wide spectrum wavelength region more.This can bring larger absorption, thereby improves the whole efficiency of battery.
Ink-jet printing technology can form thin film layer by the uniform deposition of liquid organic materials, and therefore, this technology can solve large photoactivation thing dimensional problem in theory better.Drop on demand ink jet technique, can be accurately by deposition of material in position in the desired amount.Because ink-jet system is very high to the utilization ratio of material, can reduce manufacture production cost.
For adapting to above industrial requirement, we have invented flexibility or the fluorine-based nanometer aluminium powder ink of light-cured type light-cured type fluorin modified crylic acid base base ink-jet printer for thin-film solar cells.This ink passes through ink jet printing device, both can be used in the backlight place of thin-film solar cells, the light inlet film surface that also can be used in thin-film solar cells, also can be used in the middle layer of thin-film solar cells simultaneously, improves the efficiency of light absorption of solar cell.Improve the generating efficiency of solar cell.When ink directly prints to solar cell surface, thin-film solar cells has self-cleaning effect.
