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 comprises a flexible solar battery, and the flexible solar battery is provided with a first surface and a second surface opposite to each other; a flexible glass cover sheet is arranged on the first surface of the flexible solar cell; 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 interconnection sheet; and the thickness of the flexible CIC battery is 100 [mu] m to 300 [mu] m. According to the invention, full flexibility of the CIC battery is realized, and full flexibility can be realized based on the solar cell array, so that the solar cell array has smaller folding volume and lighter weight, has higher power on satellites with the same volume and weight, carries more effective loads, and saves satellite cost and launching cost.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a flexible CIC cell and its preparation method and application. Background technique [0002] At present, artificial satellites, spaceships, space stations and other spacecraft all use solar cells to obtain energy for continuous operation. After the solar cells are welded with interconnection strips, welded with bypass diodes, and pasted with anti-radiation glass covers, they become independent components, referred to as CIC cells (connector and cover integrated cells). [0003] The technology adopted in the spacecraft solar cell array in the related art is generally the rigid array technology, and the rigid substrate and the rigid CIC battery are its basic constituent units. The traditional rigid solar array uses 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 hone...
