Growth of perovskite SCTF. a Schematic diagram of the growth process. The surfaces of two glass substrates are treated to be hydrophobic and put face-to-face to create a confined space. We then keep a constant growth temperature of 80 °C and add the precursor into the gap continuously via capillarity effect to grow the SCTFs. b Photograph of a centimeter-scale perovskite SCTF grown inside two hydrophobic substrates. c Millimeter-scale single-crystalline flakes grown inside two untreated substrates
