Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of space power supply preparation process, in particular to a flexible solar cell module packaging device and a packaging method. BACKGROUND

[0002] The launch cost of transport rockets in China is very high, and the demand for weight reduction of the launched load is extremely urgent, which puts forward higher requirements for the accommodation volume and high weight-to-power ratio of satellites. At present, the space solar power system mainly relies on rigid gallium arsenide solar cells. The manufacturing of rigid gallium arsenide solar cell modules mainly includes the following steps: first, welding single cells; second, glass cover plate packaging; and finally, series welding through resistance welding. The rigid gallium arsenide solar cell module has the following characteristics: 1) the single solar cell cannot be bent, and cannot be rolled for storage; and 2) the thickness is large, and the weight-to-power ratio is low. Flexible thin-film gallium arsenide solar cells have the characteristics of lightweight and high specific power, but the flexible thin-film gallium arsenide solar cell module with same-face electrodes cannot be packaged and then series-welded.

[0003] At present, there are many reports on flexible thin-film gallium arsenide solar cells at home and abroad, but there are few reports on the packaging process of flexible thin-film gallium arsenide solar cell modules with same-face electrodes. The flexible thin-film module with same-face electrodes can only be series-welded through resistance welding and then cover-plate packaged, because the electrodes are on the same face. The series-welded module is a flexible connection by rolling, and the module is long, so the packaging is difficult. In addition, the packaging material is different from the adhesive film used in ground photovoltaics, and liquid space silicone can only be used for packaging in space environment, so the manufacturing process has seriously limited the space application of flexible thin-film gallium arsenide solar cells.

[0015] Optionally, the upper cover overturning mechanism can rotate by 0°-180° after the cover sheet is adsorbed.

[0016] The application further provides an encapsulation method of the flexible solar cell assembly encapsulation device, which at least comprises the following steps:

[0017] Step one: after the flexible solar cell assembly is connected and welded, the flexible solar cell assembly is overturned on a string welding platform, and a glue overflow protection film is attached on the back of the flexible solar cell assembly.

[0018] Step two: cover sheet positioning is performed on a cover sheet positioning tool, and a glue overflow protection film is attached on the front of the cover sheet.

[0022] Step six, after gluing is completed, start the mold closing power mechanism to close the upper platform vacuum support structure and the lower platform vacuum support structure to form a closed cavity;

[0023] Step seven, degas the closed cavity, and after degassing is completed, vacuum pressing is performed.
