Fig. 1. Top-view (a–d) and cross-sectional (e–h) SEM images of perovskite films deposited at unpreheated substrate (as-grown) and at different antisolvent ATPs on preheated substrates at 70 °C. Insets are a photographic image of each sample before (a-d) and after annealing (e-h). Scale bars correspond to 500 nm (a–d) and 1 µm (e–h).
