Description
Technical field
The present invention relates to a kind of Salar light-gathering VCM film and application thereof, the invention still further relates to and containThe solar-energy photo-voltaic cell of this VCM film.
Background technology
Solar energy is inexhaustible resource. The advantage of solar energy is that source is free, andCan not produce greenhouse gases, with other forms of regenerative resource, as wind energy is compared, solar energy is sourceEnrich the most and the most stable energy. Utilize solar energy to carry out the emphasis class that cheap generating is new forms of energy researchOne of topic, its method mainly contains two kinds: one is solar energy to be transferred to heat energy generate electricity, and another kind is lightVolt generating. Photovoltaic generation has been developed the multiple semiconductor optoelectronic battery such as silicon, GaAs, especially along withThe maturation of monocrystalline silicon and polysilicon photocell technology, and because its output is large, cost performance other light relativelyThe feature that battery more has superiority, thus make its application surface the most extensive.
At present, what monocrystalline silicon/polysilicon photovoltaic cells mainly used is flat plate array formula, according to research, itsEnergy conversion efficiency only has 15～19%. The main cause that its energy conversion efficiency is not high is that its surface is directAccept solar radiation energy, because irradiated energy density does not reach unit are photovoltaic cellGood efficiency, thus cause the energy conversion efficiency of photovoltaic cell always in reduced levels. And monocrystalline silicon/The production of polysilicon belongs to again highly energy-consuming, high pollution industry, and the unit cost of production is higher, makes the sunAll-round popularization and the use of energy photovoltaic generation industry are subject to restriction greatly and restriction. Therefore, if inventionOne is installed or material cheaply, can realize and can carry out high-efficiency reflective and poly-to solar radiation simultaneouslyJiao, just can realize and improve the energy per unit area density being irradiated on monocrystalline silicon/polysilicon photovoltaic cells,The energy conversion efficiency that must greatly improve monocrystalline silicon/polysilicon photovoltaic cells, reduces photovoltaic electric greatlyThe use amount in pond, and can reduce from demand source the consumption of photovoltaic cell to monocrystalline silicon/polysilicon, finalAlleviate energy resource consumption and environmental pollution. There are documents and materials to show, at the concentrator solar cell neck of 2005Territory, Japanese sharp studies the experiment Photospot solar of successful light concentrating times 500, conversion efficiency 36% and sends outMotor, and U.S. spectrolab studies successful light concentrating times 170, conversion efficiency reaches 37.2% experimentConcentration solar generating unit, (" a kind of novel solar energy light gathering device ", Wang Ziqiang, " SOLARENERGY》，2008，2）。
For this new technical field, all carry out at present both at home and abroad having the opening of concentrator of this type of performanceSend out, but in the application of these technology, the carrier that plays optically focused effect generally adopts toroidal lens or carries outBend glass or the metallic object of metal coating surface processing. First aspect, because these curved face objectsThe more difficult acquisition of flatness of coat of metal basal plane, makes them after having carried out coat of metal processing, realOn border to solar radiation energy reflection efficiency not high (only 80% left and right); Second aspect, to these thingsEfficiency that body carries out coat of metal processing is low, processing cost is high; The third aspect, their coating normallyFine silver is plated to surface by ion sputtering, also causes it to manufacture processing cost quite high; The 4thAspect, because these curved bodies, from great, support while causing practical application and solid mechanical also must be eager to excelDegree is enough, finally makes whole solar energy light-collecting battery structure heaviness, cost is high and be not easy to safeguard,Actual application value high and fail to form large-scale production and actual the application (" solar energy that drops into alwaysVolt concentrator technical progress ", vast stretch of wooded country is great, Zhang Xuemei, clock hero, " SOLARENERGY ", 2008,8）。
Chinese patent application 200810001420.6 discloses a kind of reflective membrane, its select 4～5 thickPET is high, and transparent plastic film does base material, aluminizes with vacuum coating equipment, at base material at the double-face vacuum of base materialA face that is coated with aluminium film on be coated with oiliness pressure sensitive adhesive, end liner face is pasted up; At another of base materialBe coated with organosilicon 101 glass resins that are added with 550 curing agent on the face of aluminium film with coating machine roller coat. This is anti-More than the face coat hardness of light film arrives 4H, reflecting rate can reach 85%, reflective membrane can use 3 years withOn. This reflective membrane is generally used on solar cooker. Because its reflecting rate only can reach 85% left and right, thereforeBe not suitable for the optically focused purposes of solar-energy photo-voltaic cell. The condensing film of solar-energy photo-voltaic cell is wished reflecting rateCan reach more than 90%, only in this way could effectively reduce condensing film area, reduce Salar light-gathering coverOverall structure weight, and realize the raising of photovoltaic cell conversion efficiency.
Summary of the invention
Technical problem to be solved by this invention has been to overcome the coat of metal basal plane of existing concentratorBe difficult to obtain flatness, preparation difficulty, efficiency is low, processing cost is high, structure is heavy, be not easy to maintenance,Actual application value is low, thereby causes the low defect of monocrystalline silicon/polysilicon photovoltaic cells energy conversion efficiency,A kind of Salar light-gathering VCM film and application thereof are provided. The present invention also provides and has contained this sunThe solar-energy photo-voltaic cell of VCM film for energy optically focused. Salar light-gathering of the present invention VCM filmReflection efficiency to the luminous energy from face direction, infrared ray energy significantly improves, can reach more than 92%,Rub resistance, weather-resistant property are strong, also have excellent anti-ultraviolet function simultaneously, anti-oxidant, corrosion-resistant,Greatly strengthen service life, can be processed into easily the curved surface concentrator of various shapes. Be applied toWhen solar-energy photo-voltaic cell, because solar energy reflection efficiency is high, therefore can greatly improve solar photovoltaicThe solar energy conversion efficiency in pond, and significantly reduce the frame for movement weight of photovoltaic cell, be all kinds of luxuriant and rich with fragrance alunitesThe low cost upgrading of that lens type concentrator, parabola groove reflecting condenser, dish formula reflecting condenser is producedProduct.
The invention provides a kind of Salar light-gathering VCM film, it comprises that a surface sclerosis is coated with successivelyLayer, a transparent thin film layer, one strengthen light transmittance coating, a vacuum metallization processes coating, an adhesive layer withAn and base membrane layer; Wherein, this hard surface coating (Hard-coating) is polyurethane ultraviolet curing paintingThe bed of material (claiming again polyurethane UV dope layer), it has the hardness being equivalent to more than pencil hardness 2H, itsThickness is more than 0.8 millimeter; This enhancing light transmittance coating is highlighted paint coatings.
In the present invention, described VCM is term of art. In household electric appliances, VCM is " coloured silkChromatograph laminated film-covered colored steel " abbreviation, covering material wherein is called " VCM film ", also can be described as" compound color film ".
