Abstract
The utility model relates to a solar power-generation corrugated plate. A traditional solar power-generation technology can not make full use of a limited space at the top of a building, the installation is complicated, and the direction of sunlight also determines the power-generation efficiency. The product comprises a corrugated plate (2), wherein an aluminum basal plate (4) is connected on the corrugated plate by a biologic adhesive (3), a polycrystalline silicon substrate (5) is arranged on the aluminum basal plate, the outside of the polycrystalline silicon substrate is provided with a transparent resin layer (6), and the other face of the corrugated plate is provided with a lead box (1). The product is used as a construction material which can utilize solar energy.
Description
Technical field:
The utility model relates to a kind of constructional materials that can utilize solar energy, is specifically related to a kind of solar electrical energy generation corrugated sheet.
Background technology:
Twentieth century seventies, because the influence of twice oil crisis, photovoltaic generation is worldwide paid much attention to.Under the radical government in more than 40 market, the whole world supported to promote, solar energy terminal use's demand had substantially exceeded production capacity, the blank in China whole photovoltaic Enterprise Administration Office in " shortcoming relatively ".At first, from technology and economy angle analysis, the opportunity that photovoltaic generation is applied is ripe gradually.Several years in past, the innovation of technology and manufacturing process has promoted the prolongation of raising, product life cycle and product stability of expansion, the production efficiency of industrial market, and the equipment that also makes is installed and become easy.In Germany, through the research in 60 years, made generating efficiency improve 100%, stable operation is more than 25 years, and cost is then annual to reduce 6%.The reduction of average unit cost and product price makes solar energy industry more and more stronger with respect to the competitiveness of common energy industry, more and more worthwhile economically.The analysis showed that, at the ratio of present photovoltaic plant effective system power and transmission distance during, build the more conventional electrical network of photovoltaic plant and extend and power more economically less than 100 watts/kilometer.Therefore, photovoltaic generation is the important channel that solves outlying district and special dimension power supply.Secondly, the demand growth of the powerful boosting solar cell of various countries' energy policy.Advanced country in the world such as Germany, Japan, the U.S. have been included solar energy in the energy reserves strategy at present, and this causes the market growth in the global range lasting and rapid.Report according to CLSA is estimated, the increase of production rate of the main solar cell producer in the whole world all will keep 30% annual growth rate before 2010, according to this speed, more than solar-electricity volume production amount will increase by 4 times to 2010 6GW from 1.5GW in 2005.For battery, most important technical indicator is a conversion ratio.The highest QCells of present global conversion ratio can reach 16.5%-16.8%, and by the industry universal law, 1% poor conversion is different to mean that 8% profit is poor.In China, the efficient of laboratory photovoltaic cell has reached 21% at present, but commercialization photovoltaic module efficient reaches 14-15%, general commercialization battery efficiency 10-13%.The overseas market demand brings rare development opportunity for Chinese photovoltaic industry.It is predicted that the manufacturing enterprise of several solar cells that China is main all will be that order is full in two years in future, business performance is gratifying.But along with the acceleration that state's photovoltaics such as U.S., day, moral are expanded production, this situation also will change.China's solar cell production capacity in the recent period enlarges rapidly, according to the relevant person of project team of World Bank of National Development and Reform Committee introduction, calculates by the scale production capacity that reports at present, and the solar cell production capacity of China in 2010 will rise to 2450 megawatts by about 150 megawatts in 2005.Existing solar energy generation technology can not make full use of the limited space of top of building, and complexity is installed, the generating efficiency of the direction of sunlight decision simultaneously.
Summary of the invention:
The purpose of this utility model is to provide a kind of solar electrical energy generation corrugated sheet at present application demand to solar energy, can be used as building materials and be directly used in the attic room lid, make full use of the limited space of top of building, for energy charging on daytime, use for room lighting and household electrical appliances with the sunshine.
Above-mentioned purpose realizes by following technical scheme:
The solar electrical energy generation corrugated sheet, its composition comprises: corrugated sheet, connect aluminium base by the biological bonding agent on the described corrugated sheet, and have polycrystalline silicon substrate on the described aluminium base, described polycrystalline silicon substrate has transparent resin layer outward, and described corrugated sheet another side has pull box.
The beneficial effects of the utility model:
1. the utility model is directly used in the attic room lid as building materials, makes full use of the limited space of top of building, is fit to the demand of various building typess, surface spreading transparent resin reduces the surface reflection, changes the path of light in cell body, help light and absorb, simultaneously, can be self-cleaning.This project is when design, and the technology of key breakthrough is: ultra-thinization of structure, outward appearance becomes more meticulous, cheapization, installation specificationization.
2. the utility model is integrated building materials and solar energy photovoltaic panel, utilize high-strength environment-friendly type corrugated sheet, compound polysilicon crystalline material, external application high transparent resin, adopt serigraphy and bury grid technique, it is present below 200 microns that cell thickness is reduced to by original 300 microns.Efficient is greatly enhanced, and generating efficiency reaches 17%.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
The solar electrical energy generation corrugated sheet, its composition comprises: corrugated sheet 2, connect aluminium base 4 by biological bonding agent 3 on the described corrugated sheet, and have polycrystalline silicon substrate 5 on the described aluminium base, described polycrystalline silicon substrate has transparent resin layer 6 outward, and described corrugated sheet another side has pull box 1.
The manufacturing process of this product is as follows: manufacture the freezing method of high-strength self thermal insulation corrugated sheet → the manufacture solar energy aluminium base identical with the corrugated sheet shape → directly and make polysilicon square substrate → employing screen printing technique and manufacture the aluminium base of photovoltaic panel → have polysilicon photovoltaic panel and be bonded on the corrugated sheet; the spreading transparent resin forms coating on photovoltaic panel, and the apolegamy → general assembly of → accumulating system apolegamy → controller apolegamy → lightning protection system is synthesized → detected.
