Sn-doped In2O3 (ITO) electrodes were deposited on transparent and flexible muscovite mica. The use of mica substrate makes a high-temperature annealing process (up to 500 degrees C) possible. ITO/mica retains its low electric resistivity even after continuous bending of 1000 times on account of the unique layered structure of mica. When used as a transparent flexible heater, ITO/mica shows an extremely fast ramping (<15 s) up to a high temperature of over 438 degrees C. When used as a transparent electrode, ITO/mica permits a high-temperature annealing (450 degrees C) approach to fabricate flexible perovskite solar cells (PSCs) with high efficiency.
