Abstract
The utility model discloses a solar cell module packaged by polyolefin films. The solar cell module comprises a reinforced glass layer, a first film player, a battery layer, a first bus bar, an EPE isolation layer, a second bus bar, a second film layer and a backboard layer which are in lamination, wherein the first film layer and the second film layer are polyolefin films. The periphery of the solar cell module is sealed by an aluminium frame. According to the utility model, the polyolefin material is used instead of the commonly-used EVA material, so that the cell can be protected from environment aging, and the risk of dysfunction of the module during use is reduced, thereby prolonging the service life of the module and reducing the cost of the power generation of the power station.
Description
Technical field
The utility model relates to a kind of polyolefin adhesive film encapsulation solar module.
Background technology
Energy shortage and environmental protection are the common issue with of facing mankind.For the mankind of 21 century, sunlight as a kind ofly can infinitely utilizing, the novel renewable energy of environmental protection, itself be exactly wealth.Under global energy background in short supply, the status of the regenerative resources such as solar energy is more and more important.
In photovoltaic module process of manufacture, to use EVA as packaging adhesive film at present, solar module in use easily occurs that EVA is aging, xanthochromia causes assembly light transmittance to reduce, the problems such as power attenuation inefficacy, and under sunlight effect, the metal parts such as backboard, electrode and welding that can discharge on the one hand acetic acid corrosion solar cell, serious corrosion even can cause and open circuit.On the other hand, expansion in view of current photovoltaic module range of application, in humid area, there is the potential electromotive force induction of PID(decay) phenomenon more and more, the generating efficiency decay of assembly is serious, and EVA as encapsulating material under hot and humid condition, easily form electric leakage path, directly cause power station investment repayment risk to strengthen.
TPO is a kind ofly to take ethene as basic copolymer.There is uvioresistant, the feature such as water vapor transmittance is low, low-temperature impact resistance is high, easy processing.Compare with EVA material, polyolefin has good weatherability and stability of material.
Utility model content
Utility model object: the purpose of this utility model is the deficiency for existing EVA packaging adhesive film, a kind of ageing-resistant series of problems bringing that both can overcome is provided, can avoid again the polyolefin adhesive film encapsulation solar module in the serious decay of high temperature wet environment emergent power, thus the use of Assurance component safety and stable.
Technical scheme: polyolefin adhesive film described in the utility model encapsulates solar module, comprises toughened glass layer, the first adhesive film, battery pack layer, the first busbar, EPE separator, the second busbar, the second adhesive film and the backsheet layer of stacked setting; In battery pack layer, between a plurality of cell pieces, by being coated with tin copper strips, be in series from beginning to end successively; Described the first adhesive film and the second adhesive film are polyolefin adhesive film, and solar module surrounding is sealed by aluminium frame, and mechanical support and protection are provided.
Outside backsheet layer, lead-out wire position is provided with terminal box, and the lead-out wire in battery pack layer passes EPE separator and backsheet layer and is welded on the binding post of terminal box, then with casting glue by its embedding, can effectively guarantee conduction reliability.
Preferably, the thickness of aforementioned polyolefin adhesive film is 0.4-0.6mm.
Beneficial effect: because polyolefine material has superior electrical insulation capability than EVA, blocked the leak channel of cell piece under hygrothermal environment, thereby provide a feasible solution for solving the PID phenomenon of assembly.Use polyolefin to carry out the encapsulation of solar components, without the generation of acetic acid gas, avoided the aging xanthochromia of EVA, cause the situation that light transmittance declines to produce, thereby can guarantee continual and steady power stage.Polyolefine material water vapor transmittance is extremely low, greatly reduces the potential safety hazard that backboard delamination, bulge appear in assembly in subsequent production, increases the service life.In addition can be more flexible according to the appearance design of client's demand assembly, be no longer dependent on the mode of assembly edge silica gel sealing.Polyolefine material shock resistance is at low temperatures better than EVA, is mainly reflected in vitrification point lower, thereby can protect better at low temperatures cell piece, prevents that fragment from producing.
