Problems solved by technology

[0006] At present, the existing technology, such as the Chinese invention patent with the publication number CN102414838A, discloses the use of PPE materials to replace the PET materials of the prior art as the main material of the solar backsheet, although this patented technology avoids the existing conventional solar backsheet. There are technical problems of poor heat and hydrolysis resistance, but in addition to the technical problems of poor UV resistance, PET materials also have the technical problem of poor adhesion to filling resins, which makes PPE materials the main body of solar backsheets materials are limited

Abstract

The invention discloses a solar energy backboard, a packaging structure and a solar energy cell assembly. The solar energy backboard comprises an adhesive layer, a main body layer and an ultraviolet resistant layer. The main body layer is arranged between the adhesive layer and the ultraviolet resistant layer. The adhesive layer is a sea lake island cladding structure comprising multiple island units which are formed by main body material phases of the main body layer, multiple lake units which are formed by bulking agent material phases, and a sea unit which is formed by an adhesive material phase. The lake units are clad with the sea unit, and the island units are clad with the lake units. Excellent adhesive performance is ensured between the solar energy backboard and filling resin so that the solar energy backboard, the packaging structure and the solar energy cell assembly are particularly applicable to the solar energy backboard whose adhesive performance with filling resin is poor.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic manufacturing, and in particular relates to a solar backboard, an encapsulation structure and a solar battery module, and is especially suitable for being applied to a solar backboard with poor adhesion to filling resin. Background technique [0002] With the development of modern industry, the global energy crisis and air pollution problems have become increasingly prominent, so people urgently need to find renewable energy to gradually replace traditional energy. Solar energy is the core renewable energy, so in recent years, the field of solar photovoltaic has been paid more and more attention, and has achieved rapid development. Among them, the solar cell module is the core structure that directly converts the energy of sunlight into electric energy. Encapsulation protection. The packaging structure mainly includes: a transparent substrate, generally made of glass, used to cover the light-re...
