Abstract

The invention relates to a solar panel and an encapsulation process. The solar panel comprises a silicon wafer, wherein the back of the silicon wafer is adhered to a printed circuit board (PCB) board; a polythylene terephthalate (PET) material light-transmitting layer is arranged on the upside of the silicon wafer; and the PCB board is provided with anode and cathode printed coils which are connected with the anode and cathode of the silicon wafer. The encapsulation process of the solar panel comprises the following steps of: firstly, clamping the silicon wafer and flake-like ethylene vinyl acetate (EVA) hot melt glue between the PCB board and the PET material light-transmitting layer and placing the whole body in a vacuum laminating machine; secondly, vacuumizing the vacuum laminating machine and then heating materials to be processed in the vacuum laminating machine; and finally charging air into air bags in the vacuum laminating machine for pressurization.

Description

technical field [0001] The invention relates to a solar battery panel and a packaging process for the solar battery panel. Background technique [0002] A solar panel is a device that converts solar energy into electrical energy. Since solar energy is a green, environmentally friendly and renewable energy source, it has been more and more widely used. The traditional solar panel structure includes glass, silicon wafer, and bottom film, which are packaged with EVA as a whole. This can prevent external water vapor from entering the battery board and affecting the performance of the battery board. However, due to the high hardness of the glass, this structure will inevitably cause damage to the silicon wafer during packaging. Therefore, the solar panel with this structure has a high defective rate during processing. Due to the hardness of glass, this kind of solar panel will cause certain risks to users when it is used in clothing, shoes and other supplies. Moreover, this so...
