Cyclic changes of temperature in space may cause thermal deformation and thermal stresses at the silver welding spots on solar cells, which result in the solar array work abnormally. According to the temperature conditions in the thermal vacuum, the thermal stress and deformation at silver welding spot that between solar cell and inter-link chip were analyzed. The result shows that thermal cycling can make the sliver welding spot separated or contacted, which cause the solar array work wrong. The phenomenon of thermal vacuum reliability test was corresponding with these results. This paper could offer some references for the design and manufacture of solar array in the future.
