Abstract

The invention provides a preparation method of a solar cell back plate. The method comprises the following steps of uniformly mixing a graphene filler and resin sections, performing mixing, extrusion, drum sizing and bidirectional stretching in sequence to obtain a solar cell back plate, carrying out the low-temperature plasma treatment on the surface of the solar cell back plate, coating the surface of the back plate of the solar cell by using a coating, and drying and solidifying to obtain the product. Compared with the same type of patents, through the grapheme modification of the PET slice, the invention can realize thermal stability, self-cleaning performance, anti-aging performance, gas / water resistance, and ultraviolet resistance of the PET substrate of the back plate of the solar cell.

Description

technical field

[0001] The invention relates to a method for preparing a solar cell backboard, belonging to the field of photovoltaic technology. Background technique

[0002] Photovoltaic power generation is a new energy source. Through the photovoltaic effect, solar energy can be converted into electrical energy, which can be used as a green solution to replace traditional electrical energy. Photovoltaic cell modules are assembled from various semiconductor components, and are generally made of glass, battery silicon wafers, EVA, and backsheet materials by hot pressing, so they must be protected to reduce the impact of environmental effects such as moisture, oxygen, and ultraviolet rays. and destruction. Therefore, backsheets with excellent electrical insulation, interlayer bond strength, weather resistance, UV resistance, and moisture barrier properties play an important protective role in photovoltaic cell modules.
