Embodiment 1

[0041] The invention provides a method for preparing a solar module. The solar module includes a base cloth, a fourth adhesive film layer, a back plate, a first adhesive film layer, a chip, a second adhesive film layer, a water-blocking film, a third adhesive film layer and foreboard. Such as figure 1 As shown, the base cloth 17, the fourth adhesive film layer 15, the back plate 13, the first adhesive film layer 11, the chip 1, the second adhesive film layer 12, the water blocking film 14, the third adhesive film layer 16 and the front plate 18 are stacked sequentially from bottom to top to obtain an assembly structure of solar modules.

[0042]Further, the base fabric, the fourth adhesive film layer, the back plate, the first adhesive film layer, the chip, the second adhesive film layer, the water-blocking film, the third adhesive film layer and the front plate are stacked in sequence from bottom to top During the process, it is necessary to stack and place according to the...

Embodiment 2

[0064] The difference between this embodiment and Embodiment 1 is only in the setting of the lamination process parameters, which specifically include the following:

[0065] The first step is to evacuate the upper chamber and the lower chamber at the same time, set the time for the above steps to 1 minute, keep the vacuum degree of the upper chamber and the lower chamber at -90Kpa, and maintain the temperature at 140°C;

[0066] The second step is to adjust the vacuum degree of the upper chamber in sections, while maintaining the vacuum degree of the lower chamber at -90Kpa and maintaining the temperature at 140°C, including:

[0067] One-step vacuum adjustment: adjust the vacuum degree of the upper chamber to -80Kpa; at the same time, evacuate the lower chamber, set the time for the above steps to 2 minutes, keep the vacuum degree of the lower chamber at -90Kpa, and maintain the temperature at 140°C;

[0068] Two-stage vacuum degree adjustment: adjust the vacuum degree of th...

Embodiment 3

[0073] The difference between this embodiment and Embodiment 1 and Embodiment 2 lies in the parameter setting of the lamination molding process, which specifically includes the following:

[0074] The first step is to evacuate the upper chamber and the lower chamber at the same time, set the time for the above steps to 3 minutes, keep the vacuum degree of the upper chamber and the lower chamber at -100Kpa, and maintain the temperature at 160°C;

[0075] The second step is to adjust the vacuum degree of the upper chamber in sections, while maintaining the vacuum degree of the lower chamber at -100Kpa and maintaining the temperature at 160°C, including:

[0076] One-step vacuum adjustment: adjust the vacuum of the upper chamber to -60Kpa; at the same time, vacuum the lower chamber, set the time for the above steps to 4 minutes, keep the vacuum of the lower chamber at -100Kpa, and maintain the temperature at 160°C;

[0077] Two-stage vacuum degree adjustment: adjust the vacuum de...

Abstract

The invention discloses a preparation method of a solar module. The method specifically comprises the following steps of: sequentially stacking base cloth, a fourth adhesive film layer, a back plate,a first adhesive film layer, a chip, a second adhesive film layer, a water blocking film, a third adhesive film layer and a front plate from bottom to top to obtain an assembly structure of the solarmodule; and putting the assembly structure into a laminating machine, and carrying out laminating forming to obtain the solar module. According to the preparation method of the solar module, traditional two-lamination is changed into two-in-one one-lamination forming, and the sub-string stock size required by one-time lamination is the actual size, so that the adverse risk of trimming on the sub-strings is avoided; accurate lamination is realized, and material loss is avoided; and the production efficiency is improved, the production cost and the equipment loss are reduced, and the labor forceis saved.

Description

technical field [0001] The invention relates to the technical field of solar module production, in particular to a method for preparing a solar module. Background technique [0002] Solar energy refers to the thermal radiation energy of the sun, and its main manifestation is the sun's rays that are often said. Solar energy is a renewable, clean and non-polluting emerging energy that is not limited by geographical resources. It is gradually being widely used on a large scale. In modern times, it is generally used to generate electricity or provide energy for water heaters. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. [0003] There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power is a new type of renewable energy. Solar photovoltaic power generation will occupy an important seat in the world's energy consumption in...
