摘要： Mechanical scaffolds within optoelectronic devices are provided to enhance the overall thermomechanical and chemical stability of these devices. For example, extremely fragile perovskite solar cells were reinforced by scaffolding in the following way: following printing, the scaffold was sequentially filled with an electron (hole) transport layer, photoactive perovskite semiconductor, a hole (electron) transport layer, and finally capped with a top electrode. The scaffold provided structural reinforcement to the fragile perovskite layer and inhibited crack formation in the layer that would lead to device failure.
