Customer ServiceWhen designing actual structures like solar arrays, thickness is an important consideration in ensuring their stiffness [49]. Consequently, it is not feasible to assume zero thickness for the panels.

When the solar modules subjected to folding, the Jsc started to decrease and gradually saturated at around 4 mA cm -2 after 10 cycles of folding/unfolding, while the Voc almost remained constant throughout 40 times folding/unfolding, as shown in Figure 3D. Foldable solar cells with crease in the predesigned place.
Key points for achieving highly foldable solar cells Compared to the normal bendable solar cells which can endure flexion with a smooth curve with radius of several millimeters, foldable solar cells can tolerate the crease at the edge with a curvature radius of sub-millimeter.
However, in contrast to mild bending with curvature radius of several millimeters, folding generates the crease with extreme curvature radius of sub-millimeter, resulting in the appearance of large strain and stress. As a result, it is highly challenging to realize robustly foldable and highly efficient solar cells.
For the solar cells with multilayers, the folding induced crack and delamination may firstly occur in active layer or interface, depending on the stress distribution in the device during folding, the crack onset stress of each functional layers, as well as the bonding at the interface.
In the end, some perspectives for the future development of foldable solar cells, especially the standard folding procedure, improvement in the folding endurance through revealing failure mechanism, are provided.
