Morphologies of the CsBr- and CsTFA-derived CsPbBr3 perovskite films. Top-view a, b and cross-sectional view c, d FE-SEM images of CsPbBr3 perovskite films deposited on ITO/PEDOT:PSS substrates from a, c CsBr(1.7) and b, d CsTFA(1.7) precursor solutions. Insets in a and b show high magnification top-view images of the respective films
