Deployable solar cells, deployable structures, and spacecraft

摘要

PROBLEM TO BE SOLVED: To provide a deployable solar cell having a structure capable of easily obtaining more sufficient rigidity. SOLUTION: A deployable solar cell 100 includes a deployable shaft 11, and a plurality of supports 20 formed in a plane shape parallel to the deployable shaft 11 and elongated in the radial direction. Each of the plurality of supports 20 includes a support film 30 supported by one side edge (upper edge 21a) of the deployment shaft 11, and a plurality of solar cells supported by the support film 30. The support 20 includes a first support 20a and a second support 20b that can mutually open with respect to the deployment shaft 11, and a first support 20a and a first support 20b in the opening direction of the first support 20a and the second support 20b. An intermediate support 20c arranged between the 20a and the second support 20b is included, and the support film 30 is a support adjacent to each other as the first support 20a and the second support 20b are opened. It is configured so that it can be converted from the folded state to the unfolded state between the 20s. [Selection diagram] Fig. 2
