N2 - As the first step of energy conversion, thin film solar cells are very important for space solar power satellite (SSPS) to the whole wireless transmission process. The absorbance of solar energy and transmission to electricity can determine the SSPS mission straightway. However, the thin film solar cells in space are different from the ground. Based on the buckling mode superposition of the membrane wrinkles theory, this paper consider inter stress in thin film solar cells, which has contributed from the complex hot environment in orbit and error from truss, and has also analyzed the real surface figure precision (SFP) towards 100 meter, megawatt level cells. Meanwhile, due to the non-stiffness connection by two cells, this paper has also presented the dynamic characteristic of finite element method (FEM). The Time-variant curve of surface figure precision has shown. Accompanying to the microelement normal direction and absorbance, the actual energy loss in orbit has calculated.
