Problems solved by technology

[0003] Rigid and semi-rigid solar cell wings have a relatively simple deployment structure and relatively high stiffness, but are limited by the substrate thickness and installation envelope, and their power generation is usually at the level of several kilowatts; The cloth area of ​​the solar battery wing under the envelope can make the power generation up to about 20 kilowatts, but the rigidity of the flexible solar battery wing is much lower than that of the rigid and semi-rigid substrate. It is necessary to use a truss structure to improve the support of the whole wing. Stretching, its stretching mechanism is much more complicated, and the technical difficulty and risk are higher
[0004] Rigid and semi-rigid solar cell wings in our country have been used on many spacecraft in orbit, but flexible solar cell wings cannot be applied to spacecraft or space power stations due to their complicated retractable mechanism.

Abstract

The invention discloses a flexible solar cell wing. The flexible solar cell wing comprises at least two solar cell single plates; each solar cell single plate comprises a flexible substrate provided with a solar cell array and a frame, the flexible substrate is arranged in the frame, and the frame provides rigid support for the flexible substrate; every two adjacent solar cell single plates are connected through a two-way coil spring hinge. The flexible solar cell wing disclosed by the invention has the advantages of being large in output power, high in rigidity, reliable in unfolding and thelike.

Description

technical field [0001] The invention belongs to the technical field of spacecraft solar cell wings, in particular to a flexible solar cell wing. Background technique [0002] The deployable solar cell wing is an energy conversion system commonly used by spacecraft, which directly converts sunlight energy into electrical energy for use by the spacecraft. Common forms include rigid solar cell wings, semi-rigid solar cell wings, and flexible solar cell wings, each of which has its own advantages and disadvantages. [0003] Rigid and semi-rigid solar cell wings have a relatively simple unfolded structure and relatively high stiffness, but are limited by the substrate thickness and installation envelope, and their power generation is usually at the level of several kilowatts; The cloth area of ​​the solar battery wing under the envelope can make the power generation up to about 20 kilowatts, but the rigidity of the flexible solar battery wing is much lower than that of the rigid...
