Abstract

The invention discloses a packaging material for strengthening light reflection, a silicon solar photoelectric module and a film solar photoelectric module. The interior of the packaging material has a porous structure. The average bubble diameter in the porous structure is hundreds of nanometers to hundreds of micrometers to strengthen the light reflection of the packaging material. The packaging material with the porous structure is crosslinked by a chemical crosslinking method or a physical crosslinking method, and the heat resistance is enhanced, therefore, the packaging material is suitable for the silicon solar photoelectric module and the film solar photoelectric module to enhance the power generation efficiency of the modules.

Description

technical field [0001] The invention relates to an encapsulant material, and in particular to an encapsulant material with enhanced light reflectivity, a silicon crystal solar photovoltaic module and a thin film solar photovoltaic module. Background technique [0002] The structure of solar photovoltaic modules is generally composed of a front sheet and a back sheet, and the solar cells are protected in a sandwich-like manner. As for the encapsulation material, it is mainly to protect the battery and connecting lines inside the solar photovoltaic module from being eroded and damaged by moisture, oxygen, acid rain, salt, etc. in the outside air. A good packaging material can not only prolong the service life of the module, but also maintain a certain photoelectric conversion efficiency. [0003] Commonly used packaging materials are thermosetting and thermoplastic packaging materials with high light penetration. Since the refractive index (n) of the packaging material is cl...
