Description

Photovoltaic module

Technical field

The utility model is related to technical field of solar, more particularly to a kind of photovoltaic module.

Background technology

In recent years, increasingly highlighting with energy crisis, the industry that become of being generated electricity using solar energy is paid close attention to and is studied Focus.Solar electrical energy generation is divided into photo-thermal power generation and photovoltaic generation, and usually said solar electrical energy generation refers to photovoltaic Generate electricity, referred to as " photoelectricity ".Photovoltaic generation is that luminous energy is directly translated into into electric energy using the photovoltaic effect of interface A kind of technology, its key element is solar cell, and solar cell carries out packaging protection after series connection and can form big face Long-pending solar photovoltaic assembly, then it is formed photovoltaic generating system with parts such as the power controllers that closes.

For solar photovoltaic assembly, solar battery sheet is easy to damage occur by outside vibration than relatively thin It is bad, once damaging occurs in cell piece, just cannot be generated electricity, and existing photovoltaic module does not generally possess damping effect, and Without buffering between cell piece and face glass, in addition component orlop is typically than relatively thin TPT layers, without any protection, Use time is long, it may appear that aging, it is impossible to ensure generated energy, causes service life shorter.

In view of above-mentioned defect, the design people, positive research and innovation in addition, to founding a kind of photovoltaic module so as to With more the value in industry.

Utility model content

To solve above-mentioned technical problem, the purpose of this utility model is to provide one kind and possesses damping effect, it is ensured that generated energy, The photovoltaic module for increasing the service life.

The utility model proposes a kind of photovoltaic module, the photovoltaic module from top to bottom successively by upper glass surface flaggy, First EVA layer, the second EVA layer, battery lamella, the 3rd EVA layer, TPT layers, the 4th EVA layer, lower glass surface flaggy, the 5th EVA layer With antidetonation layer of silica gel composition.

Further, the thickness of the lower glass surface flaggy is the half of the upper face glass thickness degree.

Further, the thickness of the upper glass surface flaggy is 3-3.5mm.

Further, described first, second, third and fourth, the thickness of five EVA layers is identical and is 0.2mm.

Further, the thickness of the antidetonation layer of silica gel is 3-5mm.

Further, the thickness of the TPT layers is 0.3-0.4mm.

By such scheme, the utility model at least has advantages below：Photovoltaic module of the present utility model is by upper glass The bonding of first and second EVA layer between glass panel layer and battery lamella, can form buffering, battery lamella be protected, by lower glass Panel layer can cover on TPT layers, it is to avoid erosion of the external environment condition to TPT layers, prevent TPT layers aging, it is ensured that generated energy, and And increase the service life, damping effect can be played to whole component by antidetonation layer of silica gel, prevent component from receiving external impact When cell piece be damaged.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below Describe in detail bright as after.

Description of the drawings

Fig. 1 is the structural representation of the utility model photovoltaic module.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.

Referring to Fig. 1, the preferred embodiment of the utility model one：A kind of photovoltaic module, the photovoltaic module is from top to bottom successively By upper glass surface flaggy 1, the first EVA layer 21, the second EVA layer 22, battery lamella 3, the 3rd EVA layer 23, TPT layers 4, the 4th EVA Layer 24, lower glass surface flaggy 5, the 5th EVA layer 25 and antidetonation layer of silica gel 6 are constituted.

The thickness of the lower glass surface flaggy is the half of the upper face glass thickness degree.

The thickness of the upper glass surface flaggy is 3-3.5mm.

Described first, second, third and fourth, the thickness of five EVA layers is identical and is 0.2mm.

The thickness of the antidetonation layer of silica gel is 3-5mm.

The thickness of the TPT layers is 0.3-0.4mm.

The principle of the photovoltaic module is：By the bonding of first and second EVA layer between upper glass surface flaggy and battery lamella, Buffering can be formed, battery lamella is protected, TPT layers can be covered by lower glass surface flaggy, it is to avoid external environment condition is to TPT The erosion of layer, prevents TPT layers aging, it is ensured that generated energy, and increases the service life, can be to whole group by antidetonation layer of silica gel Part plays damping effect, and cell piece is damaged when preventing component from receiving external impact.

The above is only preferred embodiment of the present utility model, is not limited to the utility model, it is noted that For those skilled in the art, on the premise of without departing from the utility model know-why, can also do Go out some improvement and modification, these are improved and modification also should be regarded as protection domain of the present utility model.
