Embodiment 1

[0034] see figure 1 , figure 1 It is a schematic flow chart of the solar cell module preparation method provided by the first embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown. The preparation method is used to prepare the solar cell module as described above, specifically , the method includes:

[0035] Step S11, pasting a sealant 30 with water-blocking properties around the bottom glass 10 and the top glass 20;

[0036] refer to figure 2 with image 3 , in the embodiment of the present invention, the sealant 30 is pasted around the sides of the bottom glass 10 and the top glass 20 that are in contact with the cells, and the sealant 30 has a certain distance from the edge of the bottom glass 10 or the top glass 20 . For example: leave a distance of 2 mm to allow the sealant 30 to laminate and overflow out of the gap. Specifically, a ring of sealant 30 is pasted around the ...

Embodiment 2

[0069] The second embodiment of the present invention also provides a solar cell assembly, which is manufactured according to the manufacturing method of the solar cell assembly in the foregoing embodiment.

[0070] The solar cell module includes: a top glass 20, a battery string and a bottom glass 10 arranged in sequence from top to bottom, the top glass 20, the bottom glass 10 and the battery string are sealed with silica gel, and the edges of the top glass 20 and the bottom glass 10 are It is sealed with a water-blocking sealant.

[0071] The solar cell module in this embodiment is prepared by the preparation method proposed in the embodiment of the present invention. Compared with the solar cell module encapsulated by the existing encapsulation material, this embodiment adopts a zigzag scraping tool Apply the silica gel evenly to the top glass and the bottom glass, and form triangular concave-convex grooves on the surface of the silica gel after coating and scraping. The t...

Embodiment 3

[0073] The third embodiment of the present invention also provides a photovoltaic system, including the solar cell assembly as described in the foregoing embodiments.

[0074] In the photovoltaic system in this embodiment, in the preparation method of the solar cell module, the silica gel is evenly applied to the top glass and the bottom glass by using a zigzag scraping tool, and triangular concave-convex grooves are formed on the surface of the silica gel after coating and scraping. The triangular concave-convex grooves formed on the surface of silica gel are conducive to the uniform distribution of silica gel and the discharge of air bubbles during the coating and scraping process, which is further conducive to the extraction of air bubbles during the lamination process, which solves the problem of air bubbles and bubbling that are easy to occur when silica gel encapsulates solar cell modules to improve the sealing performance of silica gel; in addition, butyl rubber with wat...

Abstract

The invention is suitable for the technical field of solar cells, and provides a solar cell module, a preparation method and a photovoltaic system. According to the preparation method of the solar cell module, the top surface glass and the bottom surface glass are uniformly coated with the silica gel by adopting the sawtooth-shaped coating and scraping tool, the triangular concave-convex grooves are formed in the surface of the silica gel after coating and scraping, and the triangular concave-convex grooves formed in the surface of the silica gel are beneficial to uniform distribution of the silica gel and discharge of bubbles in the coating and scraping process; the extraction of bubbles in the lamination process is further facilitated, the problem that bubbles and bubbles are easy to generate when the silica gel is used for packaging the solar module is solved, and the sealing performance and the packaging effect of the silica gel are improved; and besides, sealing glue with water resistance is adhered to the peripheries of the top glass and the bottom glass, silica gel is matched with the sealing glue for edge sealing, the service life of the battery assembly is further prolonged due to the excellent water vapor resistance of the sealing glue, and the packaging effect is good.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a preparation method of a solar cell component, a solar cell component and a photovoltaic system. Background technique [0002] Solar photovoltaic power generation has many unique advantages, such as: safe and reliable, no noise, no pollution, energy can be obtained everywhere, not restricted by region, no need to consume fuel, no mechanical rotating parts, low failure rate, easy maintenance, unattended, The construction period is short, the scale is random, there is no need to erect transmission lines, and it can be easily combined with buildings. These advantages are beyond the reach of conventional power generation and other power generation methods. However, due to physical and chemical defects such as thinness, brittleness, and easy oxidation of solar cells, long-term exposure to natural conditions such as high humidity, high temperature, low temperature, strong ultrav...
