Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings. Wherein the same components are denoted by the same reference numerals.

[0028] A method for encapsulating flexible solar cell module rolls, using a single-component organic silicone glue to bond each layer of material in the module, and pressing the module 700 sequentially through multiple sets of hot pressing rollers 320, and the module 700 is extruded During the heating process, it is vacuumed at the same time. Preferably, keep the vacuum at -0.8×10 when vacuuming 5 Pa to -0.6×10 5 Pa between. The temperature of the pressing roller group 320 rises sequentially, from 50±10°C to 100±10°C, the temperature difference between the hot rollers is 1-2°C, the rolling pressure is 500-750N / pair, and the vacuuming time is 30-40 minutes , the temperature of the pressure roller group located in the front is low, the glue can be gradually heated to soften, the glue is...

Abstract

The present invention aims at the problem of low heating efficiency when packaging flexible solar cell components in the prior art, and provides a packaging method for flexible solar cell component coils. A group of hot pressing rollers located on the same conveying plane extrude and heat until the component is solidified, and vacuumize while extruding and heating the component, the vacuum degree is -0.8×10 5 Pa to -0.6×10 5 Pa, the vacuuming time is 30-40 minutes. The method of the present invention is used for component packaging, and the heating efficiency is high during the heating process. Simultaneously vacuuming during heating can make the air bubbles more thoroughly removed and the packaging effect better.

Description

technical field [0001] The invention relates to the field of processing of flexible solar cell components, in particular to a method for encapsulating flexible solar cell component rolls. Background technique [0002] Flexible solar cell components generally include three layers of materials, such as a flexible solar cell component composed of upper and lower layers of light-transmitting PET sheets and a middle layer of flexible amorphous silicon thin-film cells, and the adjacent two layers of materials can be bonded with adhesive tape , but using adhesive tape to bond components, the tape needs to be torn off after the packaging process is completed, and the film will be glued, which is troublesome to handle. [0003] In the prior art, the method of making flexible solar cell modules is that the stacked modules are heated by a heating device during the transmission process, and then the heated modules are squeezed by a pressure roller group composed of two hot rollers, one ...
