Recent research on fabricating scaffold‐type perovskite solar cells on plastic substrates has reported noteworthy progress in replacing the high‐temperature processing of TiO 2 scaffolds and compact layers with various low‐temperature processes. Herein, recent progress in the laboratory is reported regarding the development of electrodeposited TiO x compact layers and brookite TiO 2 scaffolds, both of which can be processed under 150 °C without greatly sacrificing their photovoltaic performance. Through systematic characterization of device properties and careful optimization of the fabrication conditions, a record‐high 15.76% power conversion efficiency of a plastic TiO 2 scaffold‐type perovskite solar cell is demonstrated. In addition, bending durability and preliminary stability tests on this plastic perovskite solar cell show promising results and indicate clear directions for future improvement.
