Problems solved by technology

[0002] Due to the limitations of material properties and corresponding process parameters of traditional glass components, there is no adhesive layer such as EVA or POE between the impact-resistant layer and the battery sheet, so that the energy of the thermal expansion and contraction of the battery sheet cannot be absorbed by the adhesive layer such as EVA or POE. Absorption, when applied to the BIPV field, the probability of serious defects such as delamination, slivers, and hot spots is significantly high; due to its unique process, it is more likely to cause hidden cracks, slivers, and fragments of the cell during its molding process Wait

Abstract

The invention discloses a photovoltaic tile preparation method and a photovoltaic tile. The photovoltaic tile preparation method comprises the following steps of: laminating: sequentially laying a substrate, a first bonding layer, a first impact-resistant layer, a second bonding layer, a battery layer, a third bonding layer, a second impact-resistant layer, a fourth bonding layer and a front film, and preparing lamination; vacuumizing and dehumidifying; laminating; cooling; cutting; and folding edges. The photovoltaic tile is prepared by the method.

Description

technical field [0001] The invention relates to the photovoltaic field, in particular to a method for preparing a photovoltaic tile and the photovoltaic tile. Background technique [0002] Due to the limitations of material properties and corresponding process parameters of traditional glass components, there is no adhesive layer such as EVA or POE between the impact-resistant layer and the battery sheet, so that the energy of the thermal expansion and contraction of the battery sheet cannot be absorbed by the adhesive layer such as EVA or POE. Absorption, when applied to the BIPV field, the probability of serious defects such as delamination, slivers, and hot spots is significantly high; due to its unique process, it is more likely to cause hidden cracks, slivers, and fragments of the cell during its molding process Wait. Contents of the invention [0003] The invention provides a photovoltaic tile preparation method and a photovoltaic tile. [0004] In a first aspect o...
