Embodiment 1

[0034] As a preferred embodiment of the present invention: the light transmittance of the tempered glass 2 is 95%, and the tempered glass 2 has undergone ultra-clear tempering treatment, and the position where the aluminum alloy protective layer 1 is in contact with the tempered glass 2 is provided with a seal Silica gel;

[0035] The tempered glass 2 after ultra-white tempering treatment can effectively increase the light transmittance of the tempered glass, thereby reducing the effect of light energy being reflected by the tempered glass 2, and the sealing silica gel between the aluminum alloy protective layer 1 and the tempered glass 2 can effectively improve the device. sealing performance.

Embodiment 2

[0037] As a preferred embodiment of the present invention: the upper seal 3 and the lower seal 7 are made of rubber material, and the cross sections of the upper seal 3 and the lower seal 7 are both isosceles triangles, the upper seal 3 and the tempered glass 2 It is fixedly connected by viscous glue, and the lower seal 7 is fixedly connected with the back plate 8 by viscous glue;

[0038] The cross-sections of the upper seal and the lower seal are isosceles triangles, which can play a position-limiting role when connecting the aluminum alloy protective layer 1 with the tempered glass 2 and the back plate 8, from the perspective of waterproof and dustproof. In other words, the contact area between the tempered glass 2, the back plate 8 and the aluminum alloy protective layer 1 is also increased, thereby improving the waterproof and dustproof performance.

Embodiment 3

[0040] As a preferred embodiment of the present invention: the lower battery sheet 9 and the upper battery sheet 10 are fixedly connected by EVA glue, and the bottom end of the lower battery sheet 9 and the top end of the upper battery sheet 10 are provided with multiple sets of finger electrodes and connecting welding strips It is electrically connected with the bus welding strip, the finger electrode is connected with the connecting welding strip, and the connecting welding strip and the bus welding strip are fixedly connected by welding;

[0041] It is convenient to transfer the current generated by the upper battery sheet 10 and the lower battery sheet 9 to the external circuit through the connecting ribbon and the bus ribbon.

Abstract

The invention discloses a photoelectric conversion module and a conversion method for converting optical energy into electric energy and relates to the field of a solar cell. The module involves an aluminum alloy protective layer, wherein tempered glass is connected with an inner wall of the aluminum alloy protective layer, a top end of the toughened glass is fixedly provided with an upper sealingpiece, a bottom end of the toughened glass is fixedly provided with an antireflection film, a bottom end of the antireflection film is fixedly provided with a connecting block, a bottom end of a battery piece assembly is connected with a connecting block, a bottom end of the connecting block is connected with a lower sealing piece, and a bottom end of the lower sealing piece is fixedly provided with a back plate. The module is advantaged in that the upper sealing piece and the lower sealing piece are arranged, the contact area among the tempered glass, a back plate and an aluminum alloy protective layer is increased through the upper sealing piece and the lower sealing piece, after long-time use, if silica gel connected with the tempered glass piece and the back plate cracks, the upper sealing piece and the lower sealing piece can continue to protect the device, and thereby the service life of the device is prolonged.

Description

technical field [0001] The invention relates to the field of solar panels, in particular to a photoelectric conversion module and a conversion method for converting light energy into electrical energy. Background technique [0002] A solar panel is a device that directly or indirectly converts solar radiation energy into electrical energy through the photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon". It is so large that its general use has certain limitations. Compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly. [0003] At present, the photoelectric conversion module used for solar energy, after a long time of use, the aluminum alloy protective layer is easy to create a gap between the tempered glass and the back plate, which will cause rainwater and dust to enter the device, resulting in damage to the dev...
