Problems solved by technology

[0005] In special components (such as photovoltaic modules used in roof photovoltaic systems), it is usually not necessary to use glass panels, but to use softer film materials, such as ETFE (Ethylene tetrafluoroethylene polytetrafluoroethylene) film as the component panel material, so that in the layer During the pressing process, there will be flow phenomenon after the EVA is melted or softened, which will easily lead to wrinkles on the surface of the solar cell module made of ETFE and other thin films as surface packaging materials or bubbles in the solar cell module. etc., which lead to its appearance and aging resistance not meeting the requirements of IEC61215, IEC61730, UL1703 and other standards

Embodiment 1

[0022] The preparation method of the solar cell assembly of the present embodiment comprises the following steps:

[0023] 1) Lay the backplane, the first layer of packaging film, the solar battery strings, the second layer of packaging film and the panel film in sequence. The backplane is FRP film with a thickness of 3.2mm; the first layer of packaging Both the adhesive film and the second packaging adhesive film are made of EVA film with a thickness of 0.5mm; the panel adhesive film can be ETFE film or FEP film with a thickness of 0.1mm;

[0024] 2) Set a layer of tetrafluoro cloth on the above-mentioned panel adhesive film, and the tetrafluoro cloth is the tetrafluoro cloth manufactured by Saint-Gobain in the market, whose model is CF1688;

[0025] 3) Laminate the above laminated layers in a laminator, wherein the temperature during lamination is 140-145°C; the vacuuming time is 10-15min; the lamination pressure is 800kPa; the lamination holding time is 20- 25 minutes; and...

Abstract

The invention relates to the solar cell manufacture field, specifically relating a preparation method of a solar cell assembly and a prepared solar cell assembly by utilizing the preparation method. Since in the preparation method of the invention, tetrafluoro cloth is provided on a panel glue film, then lamination technology is carried out, a surface of the tetrafluoro cloth has uniform consistent fiber lines and particles, thus in a lamination process of laminated layers, the tetrafluoro cloth can effectively control flow of a second layer packaging glue film (which is an upper packaging glue film), a problem that fold is generated on the panel glue film (such as an ETFE film) is eliminated, and a problem that a bubble is generated in the solar cell assembly is avoided. The prepared solar cell assembly by utilizing the preparation method has no fold on a surface, thus appearance and aging resistance properties of the assembly are in accordance with requirements of standards of IEC61215, IEC61730, UL1703 and the like.

Description

technical field [0001] The invention relates to the field of solar cell manufacturing, in particular to a method for preparing a solar cell assembly and a solar cell assembly prepared by the preparation method. Background technique [0002] Nowadays, energy supply has entered an era of shortage in the world, and various sustainable new energy sources have attracted widespread attention. Wherein, the utilization of solar energy is paid more and more attention by people. As an energy device, solar cells are being used more and more widely because of their unique functions compared to other energy devices and their outstanding advantages in cleanliness and environmental protection. Solar photovoltaic power generation is of great significance to alleviate today's energy crisis and improve the ecological environment. Solar cells are made of materials that can produce photovoltaic effects, such as silicon, gallium arsenide, indium selenium copper or other materials, so that ligh...
