Abstract

The invention discloses a solar array and a preparation method and application thereof. The solar array comprises an FPC and a plurality of flexible CIC batteries which are arranged in sequence. The FPC comprises a bottom layer, a printed circuit layer and a top layer which are arranged in sequence. A plurality of sub-circuits are arranged in the printed circuit layer; a plurality of positive electrode bonding pads and a plurality of negative electrode bonding pads are arranged on the sub-circuit; the positive electrode pads of the sub-circuits are connected through a wire and then current is led out to the negative electrode pad. And the sub-circuit and the flexible CIC battery are correspondingly arranged. According to the invention, the full flexibility of the solar cell array is realized, so that the solar cell array has smaller folding volume and lighter weight, and the folding volume is reduced by about 80% compared with a rigid solar array; and the weight is reduced to 30%. And the satellites with the same volume and weight have higher power and carry more effective loads, so that the cost of the satellites and the launching cost are saved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar array and its preparation method and application. Background technique [0002] At present, the technology adopted by domestic spacecraft solar cell arrays is generally rigid array technology, and rigid substrates and rigid solar cells are their basic components. [0003] In the related art, a flexible solar array technology composed of a flexible substrate and a rigid CIC battery is used. The electrical connection process is as follows: first, the CIC batteries are connected in series according to the designed number of interconnection plates to form a string, and bus bars are welded at both ends, and then the external cables are welded to the bus bars to draw out electric energy; CIC, bus bars and external cables are all Bonded to the substrate. There are problems of complex structure and large volume and weight of the finally manufactured solar array. [0004] T...
