How are solar cells loaded in a sandwich structure?

When integrated as a skin in a sandwich structure, the solar cells are loaded mainlyunder tension and compression. As silicon cells are very brittle, the critical loading mode of the face is tensile loading, which causes crack opening and propagation in the cells. Compressive forces are less critical because the cracks do not tend to propagate.
