Abstract

The invention discloses a double-layer-glass photovoltaic cell assembly and a manufacturing method thereof. Compared with a traditional double-layer-glass assembly manufacturing process, the manufacturing method has the advantages that in the laminating process, a high-temperature-resistance frame is used, so that the situations that a cell string moves and bubbles appear due to the fact that the pressure borne by the assembly is too high or uneven are avoided; after assembly lamination, the periphery of the assembly is bonded through high-temperature-resistance adhesive tape and small holes are formed in the position of the high-temperature-resistance adhesive tape in a puncturing mode, so that no bubbles exist at the edge of the assembly after the assembly is laminated.

Description

technical field [0001] The invention relates to a photovoltaic cell assembly and a manufacturing method thereof, in particular to a double-layer glass photovoltaic cell assembly and a manufacturing method thereof. Background technique [0002] For traditional double-layer glass photovoltaic cell modules, samples cannot be repaired after lamination, and there are extremely high requirements for the qualified rate of samples after lamination. However, due to the use of double-layer glass, such modules double the thickness of the module compared with conventional conventional single-layer glass modules. During the lamination process, large displacements are easily caused between the battery strings, resulting in the merging of some battery strings together. After lamination, the glass deforms due to the temperature drop during the cooling process of the component, and there will be air infiltration at the edge, resulting in edge bubbles. Contents of the invention [0003] ...
