Description
Technical field
The utility model belongs to solar-energy photo-voltaic cell technical field, particularly, relates to the backboard for photovoltaic module.
Background technology
Solar energy is a kind of inexhaustible, nexhaustible cleanliness without any pollution energy, photovoltaic generation utilizes the photovoltaic effect of interface and luminous energy directly changed into electric energy, there is safe and reliable, noiseless, low stain, can generate electricity without the need to consume fuel and erecting power transmission lines power supply and construction period short advantage on the spot, is the technology of nowadays ideal solar energy composite application.The key element of this technology is solar cell.Solar cell carries out packaging protection after series connection can form large-area solar module, then coordinates the parts such as upper power controller just to define photovoltaic power generation apparatus.And backboard is a kind of key material in photovoltaic module manufacture.The performance of backboard, have impact on the useful life of assembly to a great extent.
Photovoltaic module is generally applied in the severe area of climatic environment, needs the long-term erosion in the face of the environment such as high temperature or severe cold, high humidity, dust storm.Outside assembly must be directly exposed to, the backboard as its encapsulating material is directly subject to the rainy day, the impact of dust and other foreign material.The shortcoming of prior art dorsulum ubiquity resistance to soiling difference, the rainwater causing the rainy day to produce is failed timely eliminating and can be formed ponding and infiltrate, and accelerates the hydrolysising aging of chemical erosion and backboard, finally brings the damage of assembly.
Summary of the invention
The utility model solves the defect of solar energy backboard resistance to soiling difference in prior art, provides the photovoltaic component back plate of the high resistance to soiling in a kind of resistance to soiling good, effective prolongation photovoltaic module useful life.
For above essential technique problem, the corresponding technical solution scheme of the utility model is:
A kind of photovoltaic component back plate of high resistance to soiling, it is characterized in that described battery back-sheet successively by nano-sized hydrophobic layer, first weathering layer, substrate layer and the second weathering layer composition, substrate layer is pet layer, thickness is 20 μm, nano-sized hydrophobic layer, thickness is 5 nanometer ~ 60 micron, hydrophobic layer selects inorganic oxide, organosilan, organosiloxane, metal carboxylate, epoxy resin, acrylic resin, unsaturated-resin, one in PMMA, described first weathering layer and the second weathering layer are the coat film of fluorine resin, fluoro containing polymers resin is following one: polyvinyl fluoride, Kynoar, polytetrafluoroethylene, perfluoroethylene-propylene, fluorubber, chlorotrifluoroethylene-alkyl vinyl ether co-polymer.
First weathering layer and the second weathering layer are combined with substrate layer with coating method, and nano-sized hydrophobic layer is combined with the first weathering layer to apply coating method, and the mode of coating comprises blade coating, spraying, showering, reticulate pattern roller coat etc.
The utility model provides the photovoltaic component back plate of high resistance to soiling, and nano-sized hydrophobic layer can process the rainwater and water hybridization compound that are attached to back plate surface in time.The utility model significantly improves the resistant hydrophobic performance of backboard, the globule can be avoided in the adhesion of back plate surface, effectively prevent medium, especially the erosion on backboard and the impact on cell piece such as water, corrosive liquids (as acid rain), improve the anti-hydrolytic performance of backboard, effectively can ensure the long-term work of photovoltaic module.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In Fig. 1,1 is nano-sized hydrophobic layer, 2 is the first weathering layer of coated base sheet material layers side, and 3 is substrate layer, and 4 is the second weathering layer of coated base sheet material layers opposite side.
Embodiment
Embodiment 1,
Shown in accompanying drawing 1,
A photovoltaic component back plate for high resistance to soiling, be made up of the backboard of four-layer structure successively nano-sized hydrophobic layer 1, first weathering layer 2, substrate layer 3 and the second weathering layer 4, substrate layer is pet layer, and thickness is 20 μm.
Nano-sized hydrophobic layer, thickness is 5 nanometer ~ 60 micron, and hydrophobic layer selects the one in inorganic oxide, organosilan, organosiloxane, metal carboxylate, epoxy resin, acrylic resin, unsaturated-resin, PMMA, and the present embodiment selects organosilan.
First weathering layer 2 and the second weathering layer 4 are the coat film of fluorine resin, and fluoro containing polymers resin is following one: polyvinyl fluoride, Kynoar, polytetrafluoroethylene, perfluoroethylene-propylene, fluorubber, chlorotrifluoroethylene-alkyl vinyl ether co-polymer.The present embodiment selects Kynoar.
Preparation method: first substrate layer is carried out decontamination, surface treatment of deoiling, then applies the first weathering layer in the one side of substrate layer, heating, drying; After the first weathering layer film-forming, apply the second weathering layer at the another side of substrate layer, heating, drying; After the second weathering layer film-forming, coated with nano hydrophobic layer on the second weathering layer.
Carry out resistance to soiling test to this backboard, the anti-pollution characteristic of this backboard reaches 5 grades.Test program: dripped by burnt black ink on the coating surface, room temperature leaves standstill 48h, then uses cotton balls wiping, investigates the resistance to soiling of coating.Coating stain resistance is divided into 5 grades, and 0 representative does not have effect; 1 representative has certain effect, but still has sharp trace after alcohol wipe; 2 represent alcohol wipe after have more shallow vestige; 3 represent clear water flushing has very shallow vestige, without vestige after alcohol wipe; 4 represent clear water rinses rear without vestige.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the right involved by limiting.
