Problems solved by technology

If the elastic colloid in this thickness range is pasted with rigid materials, such as tempered glass, it can give good mechanical protection to the fragile photovoltaic cells; on the contrary, if the surface of the elastic colloid is pasted with a flexible film, it will not be suitable for the wrapped photovoltaic cells. protection is difficult to meet the requirements

Embodiment Construction

[0018] In order to illustrate the method proposed by the present invention more specifically, two detailed implementations are given below.

[0019] Option One:

[0020] In an environment with an operating temperature of 25°C, a highly transparent 0.1 mm thick ETFE film is selected as the polymer film 9, a high-quality 0.25 mm thick PET film is selected as the polymer film 10, and a photocell produced by SUNPOWER in the United States is selected as the polymer film 9. Photovoltaic cells 1 of photovoltaic modules. Weld 9 photovoltaic cells into a row, and leave the positive and negative terminals at both ends; use the liquid packaging material 8 developed by the inventor, and adjust the viscosity to 2500CPS; use figure 1 The shown gluing wheels 2 and 3 evenly coat the liquid packaging material 8 on one side of the polymer film 9 and the polymer film 10; along with the synchronous movement of the shaft rollers 4 and 5, the polymer film 9 and the polymer film 10 is laminated on...

Abstract

The present invention provides a cold packaging utilized method for manufacturing photovoltaic assembly wherein a sandwich-type photovoltaic assembly composed of a polymer, a photovoltaic cell and a polymer pressed with an axial roller at a normal temperature to completely remove air bubbles on the surface and the back of the photovoltaic cell. The sandwich-type photovoltaic assembly can be directly utilized as an ultra-thin photovoltaic assembly that finds application on an airplane, an unmanned aerial vehicle, an airship, and a waterborne power station, etc. The sandwich-type photovoltaic assembly can also be a preformed assembly for making a general photovoltaic assembly. With an ordinary connection manner that the sandwich-type photovoltaic assembly is bonded, inlayed or attached to a rigid support plate, a general photovoltaic assembly is produced.

Description

technical field [0001] The invention relates to a manufacturing method of photovoltaic cell components, especially a manufacturing method that can replace the traditional lamination process of vacuum, high temperature and high pressure, and its application includes the lamination process of photovoltaic components such as single crystal, polycrystalline and thin film . Background technique [0002] Photovoltaic modules used on the ground are affected by various harsh weather conditions and the working conditions of the ground power station environment. To meet the requirements of a working life of more than 20 years, strict packaging must be carried out, including ultra-clear tempered glass on the outer layer of the photovoltaic cell, Packaging materials for photovoltaic cells and tin-coated tapes, such as EVA, TPU, PVB, etc., photovoltaic backplanes with radiation resistance and penetration resistance, etc. To firmly bond these materials with photovoltaic cells requires a ...
