Problems solved by technology

The traditional rigid solar array uses a combination of rigid substrate and rigid CIC, which has the following problems: 1) It is not bendable. The traditional substrate is a combination of aluminum honeycomb and carbon fiber, and its thickness is generally more than 20mm; while the rigid-flexible solar array , you need to use a flexible substrate with a thickness of about 0.5mm, but because it uses a rigid CIC battery, it can only be slightly bent and placed flat and cannot be curled; 2) It is heavy, and the rigid solar array composed of rigid CIC is heavy; 3) Can not be stacked directly, large volume
Rigid CIC batteries have problems such as low power generation efficiency, heavy weight, and inability to bend; related technologies also use flexible solar array technology combined with flexible substrates and rigid CIC batteries. Flexible solar arrays also have power generation efficiency due to the use of rigid CIC batteries. Problems such as low weight, heavy weight and inability to bend

Abstract

The invention discloses a flexible CIC battery and a preparation method and application thereof. The flexible CIC battery includes a flexible solar battery, and the flexible solar battery is provided with a first surface and a second surface oppositely; A flexible glass cover sheet is arranged on the surface; a bypass diode is arranged on the second surface of the flexible solar cell; the bypass diode and the flexible solar cell are connected through a flexible interconnect sheet; the thickness of the flexible CIC cell is 100 μm ~300μm. The invention realizes the full flexibility of the CIC battery, and based on the solar battery array, the full flexibility can be realized, so that the solar battery array has a smaller folded volume and a lighter weight, and has higher power on a satellite of the same volume and weight. , carrying more payloads, saving satellite costs and launch costs.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a flexible CIC cell and a preparation method and application thereof. Background technique [0002] At present, spacecraft such as artificial satellites, spacecraft, and space stations use solar cells to obtain energy for continuous operation. The solar cell is made into an independent component after welding the interconnecting strip, welding the bypass diode and pasting the radiation-resistant glass cover, which is referred to as CIC cell (connector and cover integrated cell). [0003] In the related art, the technology adopted by the spacecraft solar cell array is generally the rigid array technology, and the rigid substrate and the rigid CIC battery are the basic components. The traditional rigid solar array adopts a combination of rigid substrate and rigid CIC, which has the following problems: 1) It cannot be bent. The traditional substrate is a combination of aluminum...
