Abstract
This invention relates to sealing method with large area and solar energy in energy field, which comprises the following steps: a, connecting the sealed solar battery chips by series or by parallel; b, overlapping from top to down in order of EVA, solar battery, EVA, PVF film, PR-4 epoxy glass fiber baseboard; c, laminating for five to ten minutes with temperature of 100 degrees; d, under temperature of 140 to 160 degrees for five to ten minutes for solidifying. This invention improves solar energy battery board with large area and power and removes glass slices and adds solar transparency to improve battery element efficiency.
Description
Technical field
What the present invention relates to is a kind of method of technical field of solar batteries, specifically, is a kind of method for packing of large area light weight solar battery.
Background technology
Traditional solar cell encapsulation method generally has two kinds: epoxy encapsulation and the encapsulation of skin glass sheet.The solar cell of epoxy encapsulation generally is that bottom is the substrate of insulation; a middle layer solar cell is the epoxy resin that one deck solidifies above, the solar cell resistance to oxidation of this type of encapsulation; high-low temperature resistant alternation and cold-resistant; insulation property are good, go back humidity, and battery component is had protective effect; the useful life of assembly is long; shortcoming is to be used in the small-power occasion, and it is great to compare, and is not suitable for the high-power condition of large tracts of land and uses.Skin glass sheet packaging technology assembly raw material order from bottom to top is PVF, EVA, battery sheet, EVA, sheet glass.The solar module of this type of encapsulation is useful in the powerful occasion of large tracts of land, and weak point is that glass and battery sheet are easily broken, and the whole mass ratio of cell panel is bigger, is not suitable for using in the occasion that weight is had requirement.
Find by prior art documents, Lin Anzhong, Zhao Xuwen, Fan Zhiqin, Shen Huayuan, Zhou Liangde is at " research of polycrystalline silicon solar cell assembly and encapsulating material " (" solar energy journal " the 13rd volume, the 1st phase, in January, 1992,33～37 pages) mention in the literary composition: the packaging technology step of solar panel: earlier with solar cell series connection welding, folded mutually according to the order of glass one EVA one solar cell one EVA-PVF film then, carry out the lamination encapsulation, assemble upper conductor again, terminal box, edge band and framework have just been finished the packaging technology of a whole set of assembly.The weak point of this method is that outermost glass ratio when being subjected to impacting is easier to fragmentation, the related damage that causes solar battery sheet of meeting, and the mass ratio of entire cell board component is bigger simultaneously, is not suitable for using in the occasion that weight is being had strict demand.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of method for packing of large area light weight solar battery is provided, make it improve the problem that large tracts of land big-power solar cell panel weight is big, sheet glass is frangible, simultaneously because removed sheet glass, increase the transmitance of sunlight, improved the efficient of solar module to a certain extent.
The present invention is achieved by the following technical solutions, the present invention includes following steps:
The solar cell silicon wafer serial or parallel connection that (1) will encapsulate connects in a row;
(2) folded mutually according to following order from top to bottom: EVA (polyethylene vinyl acetate ester), solar cell, EVA (polyethylene vinyl acetate ester), PVF (polyvinyl fluoride) film, FR-4 epoxy glass fiber substrate;
(3) lamination 5-10 minute, laminating temperature was 100 ℃;
(4) constant temperature that carried out under 140 ℃-160 ℃ 5-10 minute solidifies.Should select temperature lower in the allowed band and short time this moment, prevent that FR-4 epoxy glass fiber substrate from high temperature producing coking.
EVA is mainly used in the fixed solar battery, covers solar cell surface simultaneously it is played a protection.EVA has certain flexibility simultaneously, can resist certain impact in subrange, the protection solar cell.The effect of solar cell is that luminous energy is converted into electric energy.The acting as insulation and stop moisture of PVF film.The effect of FR-4 epoxy glass fiber substrate provides one the basis is installed, and provides enough structural strengths to the solar module after the whole encapsulation.
The present invention is the improvement of solar panel method for packing, removed the bigger and more breakable top layer cover glass sheet of quality, increased FR-4 epoxy glass fiber substrate and guarantee the structural strength of large area solar cell array under the situation that does not have the skin glass sheet.The present invention can reduce the weight of encapsulation back solar module significantly, simultaneously than using the glass packaging surface that better surperficial impact resistance is provided, can also improve about 10% (because the light transmittance of glass is about 90%) of efficient of solar module.Make the solar module that encapsulates in this way can be installed in the surface of electric automobile and building easily with a kind of form of covering.Be highly suitable for this class of solar electric vehicle to the unusual operational environment condition of severe relatively of sensitivity and solar module of weight.
