Abstract
The utility model is a crystal silicon solar cell assembly with superhigh sealing performance. The utility model is of low cost and superhigh sealing performance, so that the vapor and the corrosion gas are difficult to enter from the sealing port; therefore, the monomer battery can not be easy to be eroded, and service time is long. The utility model comprises a transparent topping glass, a monomer battery of interlinking bar connection and a backboard glass, and the above three are laminated encapsulated with EVA. The utility model is characterized in that the side parts of the topping glass and the backboard glass are fusing connected as integration, and that the leading out electrode of the monomer battery is extended from the glass which is fusing connected as integration.
Description
(1) technical field
The utility model relates to technical field of solar, is specially a kind of crystal silicon solar battery component with high sealing property.
(2) background technology
Crystal silicon solar battery component is to utilize photovoltaic effect transform light energy to be become the generator unit of electric energy.Because it is it is abominable at outdoor work environment, therefore higher to its reliability requirement.The structure of existing crystal silicon solar battery component is seen Fig. 1, it comprises that cell 3 that clear glass top layer 1, interconnector connect and material are the encapsulation backboard 4 of TPT (Tealar Polysterl Tealar), with the encapsulation of EVA2 lamination, use aluminium alloy 5 sealing-ins around it between the three.Because the cost height of TPT, be unfavorable for reducing the solar module cost, do encapsulation backboard 4 (see figure 2)s so consider to adopt glass to substitute TPT in the industry, this can reduce the cost of battery component, but this assembly is airtight, therefore steam and the etchant gas that infiltrates from the envelope interface can corrode cell 3, thereby reduced the useful life of battery component.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of crystal silicon solar battery component with high sealing property, and its cost is lower and its sealing is high, and steam and etchant gas are difficult to enter from the sealing-in mouth, cell is not vulnerable to corrosion, and useful life is longer.
Its technical scheme is such: it comprises cell and back-panel glass that transparent top layer glass, interconnector connect, encapsulate with the EVA lamination between the three, it is characterized by: described top layer glass and the fusion of back-panel glass sidepiece connect as one, and the extraction electrode of described cell connects the as a whole glass from fusion and stretches out.
It further is characterized as: the extraction electrode of described cell stretches out from described top layer glass or back-panel glass, between seal with fluid sealant; The extraction electrode of described cell adopts kovar alloy, and described kovar alloy electrode and described top layer glass and the fusion of back-panel glass sidepiece connect as one and stretch out from the fusion connecting portion.
Of the present utility model above-mentioned in, the encapsulation backboard adopts glass, can reduce cost like this, top layer glass and the fusion of back-panel glass sidepiece connect as one, outside steam and etchant gas are difficult to enter, obtain the useful life of cell prolonging, the extraction electrode of cell is drawn kovar alloy electrode and top layer glass and the fusion of back-panel glass sidepiece with fluid sealant sealing or cell between when top layer glass or back-panel glass are stretched out and is connected as one, all further guaranteed high sealing, guaranteed that battery component is than long useful life, thereby avoided existing solar module, it adopts the aluminium alloy sealing-in, the steam and the etchant gas that infiltrate from the envelope interface can corrode cell, thereby reduce the battery component shortcoming in useful life.
(4) description of drawings
Fig. 1 does the structural representation of the existing solar module of encapsulation backboard for adopting TPT;
Fig. 2 does the structural representation of the existing solar module of encapsulation backboard for adopting glass;
Fig. 3, Fig. 4 are the structural representation of two kinds of structures of the utility model.
(5) embodiment
See Fig. 3, Fig. 4, the utility model comprises cell 3 and the back-panel glass 4 that transparent top layer glass 1, interconnector connect, encapsulate with the EVA2 lamination between the three, top layer glass 1 connects as one with back-panel glass 4 both sidepiece fusions, be molten mass 7, the extraction electrode 8 of cell 3 connects the as a whole glass from fusion and stretches out.Extraction electrode 8 can stretch out from top layer glass 1 or back-panel glass 4, between with fluid sealant 6 sealing, the extraction electrode 8 among Fig. 3 stretches out from back-panel glass 4, this is embodiment 1; See Fig. 4, the extraction electrode 8 of cell 3 adopts kovar alloy, and kovar alloy electrode 8 connects as one with top layer glass 1 and back-panel glass 4 both sidepiece fusions and stretches out from molten mass 7, and this executes 2 for example, and fluid sealant 6 can adopt the general fluid sealant in market.
Claims (3)
1, a kind of crystal silicon solar battery component with high sealing property, it comprises cell and back-panel glass that transparent top layer glass, interconnector connect, encapsulate with the EVA lamination between the three, it is characterized by: described top layer glass and the fusion of back-panel glass sidepiece connect as one, and the extraction electrode of described cell connects the as a whole glass from fusion and stretches out.
2, according to the described a kind of crystal silicon solar battery component with high sealing property of claim 1, it is characterized by: the extraction electrode of described cell stretches out from described top layer glass or back-panel glass, between seal with fluid sealant.
