Embodiment 1

[0018] Example 1: The solar cell 4 is an amorphous silicon thin-film solar laminated glass module, using 3.2mm amorphous silicon cells + 0.6EVA + 3mm semi-tempered glass glass laminated glass, with a specification of 707×1640×6.8mm, and multiple battery components They are connected in series and parallel to each other to form a solar cell array for power stations. The battery module is composed of silicon-based thin-film solar cells, elastic parts, and frames packaged together. The elastic parts are installed in the frame of the battery module, and the end of the side wall covers the edge of the frame. , the electrode bus line of the solar battery array is connected with the charge controller, and the power is supplied by the output of the inverter. The elastic part in the frame of the battery module is an elastic rubber strip 3 made of thermoplastic rubber material. The thickness of the boss 3-5 of the elastic rubber strip 3 is 1.5 mm, and the thickness of the rear thin part ...

Embodiment 2

[0020] Example 2: The method of making a silicon-based thin-film solar cell assembly for a power station is: apply sealant around the solar cell, and insert the edge of the solar cell coated with sealant into the open groove of the inverted "several"-shaped elastic component , the inner wall of the elastic part is tightly sealed with the surface of the solar cell; the solar cell and the elastic part are installed in a frame filled with sealant, the end of the side wall of the elastic part covers the edge of the frame, and the sealant is covered with the inside of the frame The surface and the outer surface of the elastic part tightly seal and integrate the solar cell, the elastic part and the frame; the positive and negative electrodes of the solar cell are drawn out from the electrode lead-out piece.

[0021] Specifically: first place the solar cell 4 on a platform, clean the edge of the solar cell, and evenly coat an appropriate amount of silica gel 2 around the edge of the s...

Embodiment 3

[0023] Embodiment 3: The solar cell 4 of this embodiment is 3mm tempered glass+0.6mmEVA+0.52 polysilicon solar cell+0.6mmEVA+2mmPET, the glass is laminated glass, and the specification is 707×1640×6.72mm. The elastic strip 3 is thermoplastic rubber material, The thickness of the boss 3-5 is 1.5 mm, the thickness of the rear thin part 3-6 is 1 mm, the sealant 2 is silica gel, the frame 1 is an aluminum alloy frame, and the groove width is 10.4 mm. The series-parallel connection of silicon-based thin-film solar cell modules or the solar photovoltaic array is used as an independent power supply system. The DC power is generated and output to the controller to charge the battery, and the AC is output through the inverter for indoor electricity.

Abstract

The invention relates to a silicon-based thin film solar module and a method for a power station, belonging to the technical field of solar cells. The silicon-based thin film solar module comprises a solar cell array, an inverter, a charge controller and an electrode outgoing line, wherein the solar cell array is composed of a plurality of cell modules connected in series and / or in parallel; each cell module is composed of a silicon-based thin film solar cell, an elastic part and a frame which are packaged to one body; the elastic part is arranged in the frame of the cell module; the edge of the frame is coated by the end of the side wall of the elastic part; an electrode bus line of the solar cell array is connected with the charge controller; and the power is output through the inverter. By means of the silicon-based thin film solar module and the method, the quantity of the silicon-based thin film solar photovoltaic modules damaged by the solar cell can be decreased; the cracked problem of the solar cell can be solved; and in the meantime, sealant can be prevented form being overflowed from the edge when the sealant is filled at the edge.

Description

technical field [0001] The invention relates to a silicon-based thin-film solar photovoltaic module used in a power station and a manufacturing method thereof, belonging to the technical field of solar cells. Background technique [0002] At present, silicon-based thin-film solar photovoltaic modules used in power stations usually use glass-encapsulated solar photovoltaic modules with frames, but if such photovoltaic modules do not have edge protection, there will be a possibility of damage due to direct contact between the frame and the edge of the battery packaging glass , such as in a high-temperature or low-temperature environment, because the gap between the frame and the glass is not properly reserved, the glass and the frame will elongate or shrink to a certain extent under the influence of temperature, causing the frame to act on the edge of the glass and cause damage to the glass, or the edge of the glass If there are defects that cause glass cracking, edge protecti...
