Folding cell-built-in flexible solar cell array

Abstract

The invention discloses a folding cell-built-in flexible solar cell array. The folding cell-built-in flexible solar cell array is different from a traditional rigid solar cell array and a traditional flexible solar cell array. A substrate of the solar cell array is a flexible substrate, solar cell circuits are highly integrated, the circuits of the whole solar cell array are arranged inside the flexible substrate, and the solar cell carry in the type can achieve folding-unfolding motions and can be widely applied to a power subsystem of an air vehicle such as a space satellite. The folding cell-built-in flexible solar cell array mainly comprises a solar cell, the flexible substrate, a rigid substrate, the integrated circuits and the like. Compared with the solar cell array in the traditional modes, the folding cell-built-in flexible solar cell array has the advantages of being large in gravimetric specific power, small in folded size, high in reliability and the like, and is of great significance in the future development and the future application of the space solar cell array technology.

Description

Technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a folding and unfolding flexible solar cell array applied to a space vehicle. [0002] Background technique [0003] At present, most of the solar arrays used in space vehicles are rigid solar arrays. Semi-rigid solar arrays and flexible solar array technologies have been successfully applied to target aircraft such as the Mir space station and the Hubble telescope abroad, but there are not half of them in China. Experience in the successful application of rigid solar arrays and flexible solar arrays. [0004] With the development of space solar array technology, flexible solar array technology has become the key development direction of space solar array technology due to its advantages of high weight ratio and small power, compact size. At present, my country's space station and other target aircraft are developing flexible solar array technology. . [0005] With the development o...

Problems solved by technology

[0005] With the development of space science and technology, the requirements for solar cell array technology will become higher and higher, requiring the solar cell array to have a large expansion area, high output power, and light weight. The traditional rigid solar cell array will be difficult to meet the requirements of future development. Therefore, inventing a flexible solar cell array technology that can be folded and unfolded is of great significance to the development and application of solar cell array technology in the future
