Structure of solar battery module

Abstract

The invention relates to a structure of a solar battery module. The structure of the solar battery module comprises a back panel positioned at the bottom, wherein a lower ethylene-vinyl acetate copolymer (EVA) layer is positioned above the back panel; a battery string layer is positioned above the lower EVA layer; an upper EVA layer is positioned above the battery string layer; a toughened glass layer is positioned above the upper EVA layer; the battering string layer comprises at least two battery strings arranged adjacently; and a connecting body is in lap joint with a junction of the obverse sides or the reverse sides of the adjacent battery strings. The invention provides a production process of the solar battery module. In the process of transferring and laminating stacked modules, the battery strings are difficult to displace and the adjacent battery strings are not extruded with each other, so that the structure of the solar battery module cannot be scrapped.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a structure of a solar battery module. Background technique [0002] A solar cell module is a device that directly converts sunlight energy into electrical energy by using the photovoltaic effect. When sunlight hits the surface of the cell module, it will generate photoelectric current. The structure of the currently used solar cell module includes a back sheet at the bottom, above the back sheet is the lower EVA layer, above the lower EVA layer is the battery string layer, above the battery string layer is the upper EVA layer, and above the upper EVA layer is tempered glass layer, the battery string layer includes at least two adjacently arranged battery strings. The production process of solar cell modules includes steps such as welding the surface of the battery sheet, welding the battery string, stacking, lamination packaging, and framing. In the lamination process, the tem...

AI Technical Summary

Problems solved by technology

The disadvantage of the solar cell module with the above structure is: during the production process of the solar cell module, during the process of transferring and laminating the laminated components, the cell strings are prone to displacement, and even the adjacent cell strings may be squeezed. pressure, resulting in scrapped components, this problem caused great losses to production
