We are studying and developing a hybrid structure that combines a thin film structure and a bulk structure in order to significantly reduce the mass of solar power satellite (SPS). One of the issues of realization for SPS is the enormous number of space transportations. Therefore, to reduce the number of space transportations, we're considering replacing some of the functions installed in the bulk structure with a lightweight and thin flexible structure. In addition, it is necessary to consider thermal deformation due to periodic changes in the amount of solar radiation from the viewpoint of microwave power transmission for the SPS. In this paper, we described the results of thermal analysis of hybrid structures that combines the thin film and the bulk structure for SPS. We evaluated the thermal deformation of hybrid structure. Also, we suggested hybrid structure that satisfies a requested value which is from the microwave power transmission of the tethered SPS.
