Description
Technical Field
The application relates to the field of photovoltaic modules, in particular to a single-glass photovoltaic module.
Background
The photovoltaic module is a device for directly converting light energy of sunlight into electric energy by using the photoelectric effect of a battery. According to its interlaminar structure, can be divided into single glass photovoltaic module and dual glass photovoltaic module. The existing single-glass photovoltaic module is generally assembled according to a structure of glass-packaging adhesive film-battery piece array-packaging adhesive film-back plate, and then the packaging adhesive film is crosslinked and cured through lamination so as to bond the glass, the battery piece array and the back plate into a whole, thereby obtaining the single-glass photovoltaic module.
Because the mobility of the packaging adhesive film is good when the photovoltaic module is laminated and packaged, especially in the region of 1-2cm at the edge of the module, the packaging adhesive film is easy to overflow from the edge of the module, and further the problem of equipment pollution is caused. However, as a whole, although "flash" can contaminate the equipment, the problem of "flash" is not appreciated since it does not significantly affect the performance of the photovoltaic module.
In recent years, with the upgrading of solder strip technology, the thickness of the adhesive film is required to be thinner and thinner by customers, and the weight of the adhesive film tends to be lighter. In addition to the problem of equipment contamination caused by flash, the edge regions of the components are also affected by the adhesion caused by the thinner adhesive films.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the application provides a single glass photovoltaic module.
The application provides a single glass photovoltaic module adopts following technical scheme:
a single-glass photovoltaic module comprises glass, packaging adhesive films, a battery piece, packaging adhesive films and a back plate which are sequentially arranged, wherein at least one side of the packaging adhesive films on the two sides of the battery piece is a pre-crosslinked adhesive film; the thickness of the pre-crosslinked adhesive film is 300-800 μm.
Through adopting above-mentioned technical scheme, the glued membrane of this application adopts the pre-crosslinking glued membrane, and it obtains through pre-crosslinking by the base member glued membrane, can make the slip between some polymer chain interconnect in the base member glued membrane in order to restrain the polymer chain through pre-crosslinking, when pressurizeing the encapsulation glued membrane, can restrict the flow of encapsulation glued membrane to avoid the excessive gluey phenomenon of encapsulation glued membrane. The thickness of the pre-crosslinking adhesive film is set to be 300-800 mu m, so that the problem of edge delamination of the assembly caused by edge glue overflow of the laminated photovoltaic assembly and the weight reduction of the lightweight adhesive film of the assembly can be solved, the bonding strength of the assembly can be maintained, and the stability of the whole structure of the photovoltaic assembly can be maintained.
Preferably, the pre-crosslinking degree of the packaging adhesive film is 0.01-30%.
By adopting the technical scheme, the pre-crosslinking degree of the packaging adhesive film needs to be proper, and when the pre-crosslinking degree exceeds 30%, the bonding force of the packaging adhesive film is deteriorated, and the bonding strength of the packaging adhesive film and components such as glass is influenced. When the pre-crosslinking degree of the packaging adhesive film is preferably 0.01-30%, under the crosslinking degree, the adhesive overflow phenomenon can be avoided to the maximum extent, the problems of air bubbles and delamination of the photovoltaic module can be improved, the bonding strength between the packaging adhesive film and components such as glass can be ensured, and the stability of the whole structure of the photovoltaic module can be maintained.
Preferably, the pre-crosslinked adhesive film is a transparent film, and the light transmittance of the pre-crosslinked adhesive film is more than or equal to 90%.
By adopting the technical scheme, the pre-crosslinked adhesive film with high light transmittance can increase 15-35% of the front generated energy on the back of the module, and can greatly improve the power generation efficiency of the photovoltaic module.
Preferably, the pre-crosslinked adhesive film is one of a single-layer pre-crosslinked adhesive film, a double-layer co-extruded pre-crosslinked adhesive film and a three-layer co-extruded pre-crosslinked adhesive film.
Preferably, the single-layer pre-crosslinked adhesive film is one of a pre-crosslinked EVA adhesive film and a pre-crosslinked POE adhesive film.
Preferably, the double-layer co-extrusion pre-crosslinked adhesive film comprises an EVA layer and a POE layer.

or the three-layer co-extrusion pre-crosslinked adhesive film comprises a POE layer, an EVA layer and a POE layer which are arranged in sequence.
By adopting the technical scheme, the EVA adhesive film has good bonding strength and flexibility, and is a common base material for packaging adhesive films; compared with an EVA (ethylene vinyl acetate) adhesive film, the POE adhesive film has better water vapor barrier rate and aging resistance, but the bonding strength of the POE adhesive film to glass and a back plate is weaker than that of the EVA adhesive film because the molecular chain of the POE adhesive film is lack of polar groups. By adopting the EVA/POE double-layer co-extrusion film, the EVA/POE/EVA three-layer co-extrusion film or the POE/EVA/POE three-layer co-extrusion film, the high bonding performance of EVA and the aging resistance of POE can be simultaneously utilized, and the comprehensive performance of the photovoltaic module can be improved.
Preferably, the backsheet is a fluorine-containing backsheet or a non-fluorine backsheet.
Preferably, the back plate is one of a TPT back plate, a TPE back plate, a KPK back plate, a KPE back plate, a KPF back plate and a PPE back plate.
