Lamination preparation process of curved-surface double-glass photovoltaic module

Abstract

The invention discloses a lamination preparation process of a curved-surface double-glass photovoltaic module. Firstly, a layer of binding material covers face plate bent glass, a solar cell is arranged on the binding material, a layer of binding material covers the solar cell, and then rear plate bent glass covers on the binding material. After the panel bent glass is aligned to the rear plate bent glass, a vacuum rubber ring is sleeved on the periphery of the face plate bent glass and the rear plate bent glass, the solar cell and the two layers of binding materials are enabled to be in a closed space formed by the face plate bent glass, the rear plate bent glass and the vacuum rubber ring, the closed space is vacuumized then, the face plate bent glass and the rear plate bent glass compact the solar cell and the binding materials arranged between the face plate bent glass and the rear plate bent glass to prevent relative sliding, and an assembly to be packaged is obtained. The assembly to be packaged is placed into a high-pressure autoclave laminating machine to be carried out with lamination, and the vacuum rubber ring is removed and the curved-surface double-glass photovoltaic module is obtained after the lamination. The lamination preparation process of the curved-surface double-glass photovoltaic module can utilize one device to prepare photovoltaic modules with different radiuses of curvature.

Description

technical field [0001] The invention relates to the technical fields of vacuum lamination, high-pressure lamination and photovoltaics, and in particular to a lamination preparation process of a curved double-glass photovoltaic module. Background technique [0002] Double-glass photovoltaic modules, that is, photovoltaic modules that use glass on both the front panel and the back panel, are widely used in BIPV and solar vehicles. In applications, there is often a demand for curved surface components, especially when photovoltaic modules are used on car roofs Time. Conventional double-glass photovoltaic modules are produced by means of flat heating plates and vacuum lamination, which can only produce flat photovoltaic modules. Patents CN 202088628U, CN 202319200U, CN202378376U and CN 202428745U report laminators for curved heating panels, but for this type of equipment, a heating panel with a curvature radius can only laminate curved photovoltaic modules with a specific curva...
