Background

The flexible battery array is an important component of the flexible solar battery wing of the space station, mainly comprises 44 battery boards, cables and battery circuits, and has the function of absorbing light energy to provide electric energy for the space station. The substrate material of the battery panel is a polyimide film, the external dimension is 2400mm multiplied by 520mm, 72 piano hinges are respectively arranged on two sides and are arranged in a tooth shape, and the wall thickness of each piano hinge hole is only 0.2 mm. The surface of the substrate is pasted with a three-junction gallium arsenide cell plate, the total thickness of the cell plate is not more than 1mm, and the weight of a single cell plate is about 2 kg.

The cell array is assembled by connecting two adjacent cell plate-side piano hinges through piano hinge shafts, and the design index requires that the deflection deformation of the substrate within the area range of 30mm multiplied by 30mm is not more than 0.1mm in the process of assembling the solar cell panel. Therefore, the deflection deformation in the long side direction of the veneer should be not more than 8mm, and the deflection deformation in the short side direction should be not more than 1.7 mm. Meanwhile, in order to verify the expansion and contraction functions of the battery array under the weightless working condition, the battery array is in a hanging state after being assembled.

In the assembling process, due to the factors that the wall of the organ hinge hole is too thin, the distance between organ hinges is too small, and the organ hinges are easy to break due to mutual extrusion, great inconvenience is brought to the penetrating and assembling work of the organ hinge shaft. In addition, the base plate has large flexibility and is easy to bend, the battery glass cover plate is easy to crack under slight bending, and the battery panel is always kept in a flat state in the assembly process. The folding and unfolding functions of the battery array in space can be influenced by the cracking of the piano hinge of the battery panel, and the electric energy converted by the battery array can be reduced by the fragmentation of the glass cover plate of the battery. Therefore, it is very important to solve the assembly problem of the flexible battery array.

The preparation method of the fully flexible folding solar cell array provided by the invention can realize the fully flexible structure of the solar cell array, not only ensures the high efficiency and light weight of the cell array, but also can fold and gather the cell array with huge area into small volume, thereby saving the precious space and effective mass of an aircraft and realizing more effective loads of equipment. Said invention is easy to damage the cover glass of battery in the course of assembling.
