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 cells arranged in sequence; the FPC comprises a bottom layer, a printed circuit layer and a top layer arranged in sequence; Several sub-circuits are arranged in the circuit-making layer; several positive pads and several negative pads are arranged on the sub-circuits; the positive pads of the sub-circuits are connected by wires and the current is led to the negative pads ; The sub-circuit and the flexible CIC battery are correspondingly arranged. The invention realizes the full flexibility of the solar cell array, so that the solar cell array has a smaller folded volume and lighter weight, the folded volume is reduced by about 80% compared with the rigid solar array, and the weight is reduced to 30%. The satellites of the same size and weight have higher power, carry more payloads, and save satellite costs and launch costs.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar array and a preparation method and application thereof. Background technique [0002] At present, the technology used in domestic spacecraft solar cell arrays is generally rigid array technology, and rigid substrates and rigid solar cells are the basic components. [0003] In the related art, a flexible solar array technology composed of a flexible substrate and a rigid CIC cell is used. The electrical connection process is as follows: firstly, the CIC batteries are welded in series through interconnecting sheets according to the designed number of series to form a string, and bus bars are welded at both ends, and then the external cables and the bus bars are welded to lead out electric energy; CIC, bus bars and external cables are all connected. Glue and fix with the substrate. There are problems of complex structure and large volume and weight of the final solar a...
