Abstract

The invention provides a flexible solar cell array based on a shape memory polymer composite material and an expansion method of the flexible solar cell array, belongs to the field of space solar cells, and aims to solve the problems that an expansion control process is not stable enough, the reliability is poor, and a flexible solar cell array film expansion driving technology is not mature enough in the prior art. The flexible solar cell array based on the shape memory polymer composite material comprises a group of flexible solar cell units; one end of each flexible solar cell unit support frame (1) is fixed to a power supply body (2), and a heating layer (3) and a flexible solar cell array veneer (4) are sequentially adhered to one side of the support frame (1); a power source (5) is used for providing energy to the heating layers (3). According to the expansion method of the flexible solar cell array based on the shape memory polymer composite material, the heating layers (3) are used for rising the temperature to soften a vertical structure to enable the flexible solar cell array to be in an expanded state. The flexible solar cell array and the expansion method thereof have the advantages of being stable in movement and high in reliability.

Description

technical field [0001] The invention relates to a flexible solar battery array based on a shape-memory polymer composite material and an unfolding method thereof. Background technique [0002] As the functions of the spacecraft increase, the requirements for energy supply are increasing, and the solar cell array is gradually becoming larger. However, due to the particularity of the aerospace industry, it is required that the spacecraft components must be lightweight and occupy a small volume. In this context, as a new direction for the development of space solar cells, flexible solar cell array films are bound to play a huge role in the future aerospace field due to their advantages such as light weight, easy folding, and large storage ratio. However, there are few applications of flexible solar cell array thin films in space solar cells, and there are problems such as unstable deployment control process, poor reliability, and immature deployment drive technology of flexibl...
