Description

A kind of solar photovoltaic assembly
Technical field
The utility model relates to application of solar, specifically a kind of solar photovoltaic assembly.
Background technology
Along with China's economic is fast-developing, living standards of the people improve constantly, and also increase progressively the demand of the energy thereupon.Current energy resource consumption is mainly the fossil fuel such as coal, oil and natural gas.Because China's oil reserves are limited, at present nearly 50% crude oil rely on import, coal be still China main fuels and energy source, the environmental problem that fire coal causes has become the problem must taken seriously in China's strategy of sustainable development.Solar energy is a kind of energy of huge environmentally safe, and the solar energy of earth acquisition per second is equivalent to the energy that burning 5,000,000 tons of fat coals send.China is one of country that solar energy is the abundantest in the world, China's solar energy irradiation total amount is greater than 5,020,000 kilojoules square metre, year, the sunshine time area of 2200 hours accounted for China's area more than 2/3, particularly west area, and the hours of daylight in year reaches more than 3000 hours.
Solar module mainly makes based on semi-conducting material, and basic structure comprises framework and is arranged at the modular construction in framework.Wherein, modular construction comprises front surface glass substrate, transparent encapsulants (as EVA glue), the cell piece of printing opacity and carries on the back sealing film (rear surface guard block, as PVF polyvinyl fluoride, TPT/TPE) etc.Operation principle is that sunlight is radiated on photo-electricity generating device through substrate, and transform light energy is directly electric energy by photoelectric effect by photo-electricity generating device, through photovoltaic junction box matching used with battery component, uses after being exported by electric energy.Transform light energy is becoming in the process of electric energy by solar cell, is not all to convert whole luminous energy to electric energy.Theoretical research shows, the Theoretical Physics limit of the conversion efficiency of solar cell 0 DEG C time of one pole single crystal silicon material is 30%.Under the condition that light intensity is certain, when silion cell own temperature raises, power output will decline.In actual applications, under reference condition, crystal silicon cell average efficiency is about 15%.That is, the transform light energy of 15% can only be become available electrical energy by solar cell, and remaining 85% is all converted into heat energy.
In transfer process, along with the increase of heat energy, battery temperature constantly raises, and except photoelectric conversion efficiency reduces greatly, the useful life of solar cell also will shorten.For making solar module normally work muchly, in prior art, outside framework, add heat abstractor (be similar to the cooling system such as water-cooled, air cooling, by recirculated water or circulating air heat absorption, reach heat radiation object).But heat energy is also the part that solar module absorbs the solar radiation energy, if this part energy can be taken out and collects, be used, but not be regarded as the damaging heat that need dissipate, just can reach the object making full use of the energy, and widen the using function of solar module.Higher level is remained on for making battery efficiency as far as possible, make full use of the solar radiation energy of absorption, avoid heat on the impact of assembly photoelectric conversion efficiency simultaneously, extend the useful life of battery component, can by arranging heat-conducting layer on solar module, by the heat absorption conduction produced in photoelectric conversion process, and the heat conducting element connected by it derives modular construction, collected by extraneous heat-obtaining pipeline, be supplied to follow-up heat energy equipment use.According to its position arranged in solar components seal or outside seal, heat-conducting layer selects insulating material or highly heat-conductive material to make.Heat conducting element can be the metal species element with the high capacity of heat transmission, or the capacity of heat transmission is higher than the heat pipe etc. of metal species element.The composite component of photovoltaic and photothermal solar comprehensive utilization also has research at present, to on collecting plate mostly by thermal-collecting tube supersonic welding, collecting plate and solar photovoltaic assembly fit, or thermal-collecting tube is fixedly connected on the shady face of solar photovoltaic assembly, then heat insulating board formation is installed below thermal-collecting tube.Thermal-collecting tube is fixedly installed on the photovoltaic module back side, is hard contact with photovoltaic module and heat insulating board; And solar energy photovoltaic assembly is also known as solar module, refers to that there is encapsulation and inner Join, can direct current be provided separately to export, minimum indivisible photovoltaic cell combination unit.Photovoltaic module (being commonly called as solar panel) is combined by solar battery sheet (two kinds of specification 125*125mm, 156*156mm, 124*124mm etc. of full wafer) or the solar cell of different size cut open by laser cutting machine machine or steel-wire cutting machine and is formed.Due to the electric current of monolithic solar cell sheet and voltage all very little, then they are first connected acquisition high voltage, more in parallel obtain high electric current after, then exported by a diode (preventing electric current from feeding back).And they are encapsulated on a stainless steel, aluminium or other nonmetal frames, install the backboard at glass above and the back side, be filled with nitrogen, sealing.Entirety is called assembly, namely photovoltaic module or say it is solar module.Solar components be generally be arranged on outdoor, when facilitating fine day, the sun can be irradiated to cell panel above fully, if but running into the weather such as strong wind or hail can smash cell panel, shorten the useful life of photovoltaic module, and the sun of the convertible 15%-18% of the solar components of standard, remaining solar energy converts heat energy to and has dissipated, and the energy is not fully utilized, and practicality is not strong.
