Abstract
The invention relates to a high-efficiency black solar cell backplane and a preparation method thereof; the high-efficiency black solar cell backplane comprises a substrate layer, fluorocarbon layers and a sol layer, wherein the fluorocarbon layers are cured and formed on two surfaces of the substrate layer; and the sol layer is cured and formed between any one fluorocarbon layer and the substrate layer. According to the high-efficiency black solar cell backplane disclosed by the invention, the sol layer capable of being cured and formed is arranged between one fluorocarbon layer and the substrate layer; on the one hand, moisture can be prevented; the aging characteristic of the solar cell backplane is increased; on the other hand, because the sol layer has better adsorption capacity, the fluorocarbon layers outside are difficult to fall off; furthermore, the fluorocarbon layers are also cured and formed on the substrate layer; therefore, the process difficulty of the solar cell backplane can be reduced; and the production quality and the production efficiency of the solar cell backplane can be increased.
Description
Technical field
The invention belongs to area of solar cell, relate to a kind of solar cell backboard, be specifically related to a kind of efficient black solar cell backboard and preparation method thereof.
Background technology
Along with the exhaustion day by day of the fossil energies such as coal, oil, natural gas and the day by day serious of environmental pollution, the mankind are in the urgent need to seeking the alternative renewable energy resources.Solar energy is the abundantest regenerative resource of occurring in nature, and solar energy power generating refers to the photoelectric effect utilizing solar cell, solar radiation can be converted to the generation mode of electric energy.Solar energy have safe and reliable, noiseless, pollution-free, can easily with the advantage such as building combines, grown continuously and fast since the eighties in 20th century.
Crystal silicon cell is one of core of solar photovoltaic generation system, if be directly exposed in air by crystal silicon cell, owing to can be subject to the impact of the meteorologic factors such as light, heat, rain, snow, the conversion efficiency of crystal silicon cell and useful life can reduce greatly.Solar cell backboard, as the support of rear surface of solar cell and protective material, is that solar cell plays a role indispensable part.Traditional solar energy back veneer material is layer structure, is made up of, uses adhesive to bond between these structure sheafs the weathering layer of inside and outside layer and the substrate layer of centre.In order to cater to the demand of house class photovoltaic module aesthetic, black assembly is developed and comes into operation gradually, and the consumption of current black solar cell backboard is in the trend risen year by year.In existing technology, black solar energy backboard is composited primarily of fluorine-containing film, PET basic unit, EVA film trilaminate material.There is many defects in this type of backboard, the thicker heat transfer efficiency of such as backboard is poor, and difficulty reprocessed by assembly, and EVA long-term ageing weatherability is poor, fluorine film and PET basic unit bad adhesion etc.
Authorization Notice No. is that the Chinese utility model patent of CN203733821U discloses a kind of black solar cell backboard and solar module, this black solar cell backboard comprises basic unit, weather-proof black rete, particularly, described black solar cell backboard also comprise be formed in described basic unit one side on weather-proof black coating and be formed in the another side of described basic unit with between described weather-proof black rete for by described basic unit and the bonding macromolecular adhesive layer of described weather-proof black rete.Although this black solar cell backboard has good weather resistance, be easy to assembly and reprocess, there is lower production cost simultaneously; But the adhesive that have employed thickness between the basic unit of this backboard and weather-proof black rete thicker bonds, and makes interlayer adhesion poor, and its reflecting rate is low, causes the power reduction of solar module.
Publication number is that the Chinese invention patent of CN103872163A discloses a kind of black solar cell backboard, comprise the first black heat conduction weathering layer, substrate, barrier layer and the second black heat conduction weathering layer that superpose setting successively, described substrate inside is filled with the first resin combination; Described first black heat conduction weathering layer is formed by the second resin combination, described second black heat conduction weathering layer is formed by the 3rd resin combination, described first resin combination, the second resin combination and the 3rd resin combination independently comprise separately: the fluorine resin of 100 weight portions, the curing agent of 8 ~ 20 weight portions, the solvent of 80 ~ 200 weight portions, the inorganic filler of 50 ~ 100 weight portions, the carbon black of 1 ~ 5 weight portion, described barrier layer is formed by aluminium or silicon dioxide.Although this black solar cell backboard have employed the resin combination of high thermal conductivity coefficient, black solar cell backboard is made to have good thermal conductivity; But its barrier layer obtains in a surperficial AM aluminum metallization of substrate or silicon dioxide, this cause its processing technology complicated and assembly to reprocess cost higher, be difficult to drop into practical application.
