Abstract

The invention belongs to the technical field of photovoltaic cells, and particularly relates to a single-layer adhesive film, a multi-layer co-extrusion adhesive film and a photovoltaic cell module, and the single-layer adhesive film, the multi-layer co-extrusion adhesive film and the photovoltaic cell module comprise key function layers; the key function layer is provided with a plurality of airholes. And the diameters of the air holes are 1-10 microns. The key functional layer is composed of an electrically insulating resin. The electrical insulating resin is composed of one or more of polyolefin, an ethylene- vinyl acetate copolymer, polyvinyl butyral, an ionomer, polyurethane, silica gel, epoxy resin and ethylene propylene diene monomer. The single-layer adhesive film, the multi-layerco-extrusion adhesive film and the photovoltaic cell module have the effects that the sunlight utilization rate of the photovoltaic module is improved, so that the photoelectric conversion rate of the photovoltaic module is improved, and the performance of the photovoltaic module is improved.

Description

technical field

[0001] The invention belongs to the technical field of photovoltaic cells, and in particular relates to a single-layer adhesive film, a multi-layer co-extruded adhesive film and a photovoltaic cell assembly. Background technique

[0002] Solar photovoltaic cells (photovoltaic cells for short) are used to directly convert the sun's light energy into electrical energy. At present, silicon solar cells based on silicon are widely used in terrestrial photovoltaic systems, which can be divided into monocrystalline silicon, polycrystalline silicon, and amorphous silicon solar cells.

[0003] Photovoltaic cells are usually encapsulated under the front glass by adhesive film, so the optical properties of the adhesive film play a crucial role in the light absorption and conversion rate of photovoltaic cells.

[0004] The existing Chinese patent with the notification number CN111560228A discloses a single-layer packaging adhesive film, a composition for preparing it, a...
