Embodiment 1

[0028] As shown in the figure, a solar battery module includes a battery array, and the battery array is formed by connecting a plurality of solar battery pieces 4 in series or in parallel through welding ribbons 3, and also includes a flat plate with a cavity inside, a lead post, and a side opening The glass model 1, sealing material 2 and sealant 6; the battery array is placed in the cavity of the glass model 1, the sealing material 2 fills the space outside the battery array in the cavity, and the sealant 6 is used to seal the glass The side opening of Model 1.

[0029] Such as image 3 As shown, the battery array is formed by connecting multiple solar cells 4 in series or in parallel, and the connection mode of the battery array is selected according to the required current and voltage. The solar cells 4 can be monocrystalline silicon, polycrystalline silicon, or amorphous silicon solar cells , the specific principle and structure of the solar battery sheet 4 are well kno...

Embodiment 2

[0041] The specific method for manufacturing the solar cell module of the present invention will be described in detail below.

[0042] Including the following steps:

[0043] 1) Make a battery array: according to the needs, select solar cells 4 of appropriate size, form a plurality of solar cells 4 by welding in series or in parallel with ribbons 3, and lead out positive and negative electrode wiring and bypass diode wiring; specifically Weld the single / double-sided light-receiving solar cell 4 with the ribbon 3, then place the welded single cell in the mold and orderly weld the solar cell string, and weld the solar cell string with the ribbon 3 to form a solar cell array .

[0044] 2) Making glass model 1: Select low-iron ultra-clear glass as the material, make a mold according to the design structure during production, complete the casting and molding of glass parts according to the glass preparation process, and perform subsequent tempering treatment.

[0045] Step 1) and ...

Abstract

The invention relates to a solar module, which comprises a battery array, a glass model, a sealing material and a sealant, wherein the battery array is formed by connecting a plurality of solar battery pieces in series or in parallel through solder strips; the glass model is tabular and the inside of the glass model is provided with a cavity and a side opening; the battery array is placed in the cavity of the glass model; the sealing material is filled in the space beyond the battery array in the cavity; and the sealant is used for sealing the side opening of the glass model. The invention simultaneously discloses a manufacturing method for the solar module. The method adopts a scheme of the internal seal of the glass model with the side opening to improve the sealability, the weatherability and the photoelectric conversion efficiency of the solar module. Because a laminating method is not adopted, the phenomena of the displacement of the battery pieces, the generation of bubbles and even the crushing of the battery pieces are prevented, and the phenomena of layering stripping and ageing are prevented.

Description

【Technical field】 [0001] The invention relates to the field of solar cells. 【Background technique】 [0002] With the increasing development and progress of society, energy tends to be more tense, especially the reduction of non-renewable energy such as coal and oil, and the fields that use the above-mentioned energy are all affected, such as the transportation field. Because of the rise in oil prices, the resulting Therefore, the development and application of new energy is becoming more and more urgent, and solar energy, as a new renewable resource, is also receiving more and more attention. [0003] A solar cell module (also known as a "photovoltaic module") is a series and parallel connection of several single cells according to their electrical properties, and after packaging, they are combined into the smallest unit that can be used independently as a power source. Solar modules come in a variety of sizes and shapes, with a typical module being a rectangular flat panel...
