Description
Technical field
The present invention relates to a kind of flexibility or thin-film solar cells photocuring fluorine richness epoxy resin basement membrane and preparation method thereof, by the surface using this film to be encapsulated in flexibility or thin-film solar cells incidence surface, directly improve efficiency that is flexible or thin-film solar cells.
Background technology
Effectively utilize in the middle of project at sun power: solar photovoltaic utilization is research field with fastest developing speed in the last few years, most active.Mainly based on semiconductor material, after utilizing photoelectric material to absorb luminous energy, there is opto-electronic conversion reaction generating in the making of general solar cell.According to the difference of material therefor, solar cell can be divided into: 1, silicon solar cell; 2, with the solar cell that inorganic salt are material as multi-element compounds such as gallium arsenide III-V compound, Cadmium Sulfide, copper indium diselenide; 3, with solar cell prepared by functional high molecule material; 4, nano-crystalline solar battery etc.
What prior art working efficiency was the highest is with Group III-V semiconductor inorganic materials is raw-material product.Such as: the quantum well of the single junction type of gallium arsenide/germanium falls into crystal structure, and its photoelectric transformation efficiency can reach >18%; And multiple junction quantum well falls into the solar cell of crystal structure, such as: InGaP/gallium arsenide/germanium, its photoelectric transformation efficiency can up to >30%.Most widely used at present, based on silicon: comprise non-crystalline silicon, photoelectric transformation efficiency about 9%; Polysilicon, photoelectric transformation efficiency about 14%; Silicon single crystal, photoelectric transformation efficiency about 17%.Although in price, VI race elements Si is more cheap than Group III-V semiconductor GaAs, its price manufactured, compared with polymer organic solar batteries, or expensive many; And in application, light weight again the anxiety of crack-free overall plasticization organic solar batteries can via printing processing realize, except price reduces, be more suitable for the demand of portable electronic product, and all can normally use (this is that siliceous solar cell is beyond one's reach) at indoor or cloudy day, its practicality and market application range are promoted more.
Solar cell is a gordian technique, can advance more clean Energy production.But the Cost Problems of solar cell, reduces the economic competitiveness of heliotechnics.For overcoming this problem, thin-film solar cells is the technology of current widespread use, and can reduce the usage quantity of expensive semiconductor material in a large number, but the absorbing amount of thin-film solar cells is lower, Performance Ratio does not go up traditional solar cell.
Thin-film solar module is made up of glass substrate, metal level, transparency conducting layer, electrical function box, glueing material, semiconductor layer etc.Organic-inorganic composite solar cell 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, wet-layer preparation low cost, big area, flexible solar battery device and inorganic nano-crystal material high stability can be passed through, high mobility, can the advantages such as ordered nano-structure be constructed, and become the study hotspot of area of solar cell in recent years.Metal nanoparticle direct light can enter solar cell better, prevents light from escaping.In traditional " thick film " solar cell, nanoparticle does not have any effect, because it is all by this film that all light absorbs, this just relies on its thickness.But for film, nanoparticle just can play great role.Their scattering adds the light stop time in the film, and make the light of overall absorption reach a kind of level, can match in excellence or beauty traditional solar cell.
Aluminium and Nano silver grain, in the frequency spectrum of visible part, can enter solar cell by focused ray well.But optical resonance also can cause nanoparticle absorb light, this just means that the efficiency of 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 is beyond the crucial spectra part of solar cell.Less to the loss of energy, 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, thus improves the whole efficiency of battery.
Due to the special property of fluorine atom; fluoropolymer forms the leptospira structure of F atom at periphery parcel C-C main chain, and C-F key is highly stable, and bond energy is 485kJ/mol; fluorine atom is very tight in the outer field arrangement of carbon skeleton, can form shielding protection to main chain and interior molecules.Protection C-C main chain does not destroy by severe environmental conditions, and keeps the stability of height.Organo-fluorine polymer material molecule side base or side chain contain the stronger fluorine atom of sterically hindered less and close power, make its surface free energy very low, show excellent waterproof and oilproof, contaminated resistance. therefore fluorocarbon coating has the special performance that some other coating hardly match, such as: fabulous weathering resistance, excellent chemical resistance, low abrasiveness, hydrophobic nature, oil repellency, uninflammability etc., it is applied in many Application Areass, more and more receives the concern of coating circle personage.
Epoxy resin has excellent tack, thermostability, chemical-resistant, insulativity and physical strength etc., is widely used in the fields such as coating, tackiness agent and matrix material.Epoxy resin itself is insoluble in water, also not easily disperses in water, prepare aqueous epoxy emulsion and mainly contain 3 kinds of methods at present: mechanical process, phase inversion (solidifying agent emulsion process) and chemic modified method.Wherein chemic modified method has plurality of advantages relative to first two method: do not need additional emulsifying agent, water-fast solvent resistance is high, emulsion particle diameter is little (nano level), stability in storage is good, state of cure is high, film dense uniform.In recent years, acrylic monomer is utilized to carry out graft modification epoxy resin, do not consume epoxy group(ing) and hydroxyl, the emulsion particle diameter obtained is little, emulsion intercalation method is good, both there are the high-modulus of epoxy resin, high strength, chemicals-resistant and excellent preservative property, there is again the features such as acrylic resin gloss, fullness ratio, good weatherability.Aqueous epoxy resins has the advantages such as excellent sticking power, high-modulus, high strength, chemical-resistant and preservative property, epoxy resin is utilized to carry out blending and modifying to fluorinated acrylate emulsion, water-fast, solvent resistant, sticking power and the mechanical property of coating can be improved, under the condition not affecting service requirements, significantly reduce coating cost simultaneously.Wang Yifeng etc. have prepared epoxy resin modification acrylate copolymer composite emulsion by physical blending process, fluorine-containing latex and epoxy emulsion carry out blended by the total root of Qin etc., during discovery film forming, resin can produce self demixing, and the film obtained like this has excellent surface property and good adhesion property.(1. Wang Yue glad, Wang Jingke, Zhang Qian, Zhai He, Wang Fang, with the modification of epoxide group fluorinated copolymer to epoxy coating, " polymer material science and engineering " 2012 year 03 phase.2. the little dragon of Xu, Li Baosong, Wu Xuedong, Hexafluorobutyl mathacrylate grafted epoxy powder coating is studied, " coatings industry ", the 4th phase 56-59 page in 2010)
Summary of the invention
