Abstract

The embodiment of the invention discloses a flexible solar cell array adaptive to a roll type solar wing, which comprises a first bus bar, n solar cell chips, a flexible front plate film and a second bus bar. The n solar cell chips are flexible CIGS thin film solar cell chips; n is a natural number; a bus grid line and a bypass diode channel are integrated on the flexible front plate film, and the bus grid line and the bypass diode channel are printed for integrating the n solar cell chips into a solar cell array; the flexible solar cell array is matched and designed by correspondingly adjusting the number of solar cell chips in the solar cell array and the area of the flexible front plate film according to the size of the roll type solar wing. The flexible solar cell array provided by the invention is flexible in size design, and the length and the width of the flexible solar cell array can be adaptively designed according to the length and the width of the roll type solar wing, so that roll type solar wings of various specifications can be met, and the applicability is high.

Description

technical field [0001] The invention relates to the aerospace field. More specifically, it relates to a flexible solar cell array adapted to roll-type solar wings. Background technique [0002] In the field of aerospace, monocrystalline silicon cells were mainly used as spacecraft power products in the early days. In recent years, gallium arsenide-based solar cells are mainly used to power spacecraft. On the solar wing mechanism or the satellite body, the solar cell array is formed by connecting solar cells in series and parallel to realize power supply for the spacecraft. Monocrystalline silicon cells are mainly prepared with silicon as the material, and gallium arsenide-based cells are mainly made of germanium materials as the substrate. The physical properties of these materials are relatively thin and brittle, and they cannot be rolled. They are generally fixed on the flat solar wing substrate by pasting. Or on the deck, a solar array is formed to provide power for the...
