Fig. 6

a Normalized PCE of f-PSCs as a function of bending cycles at a radius of 5 mm. Inset is a photo of the bending test. Error bars represent the standard deviations from the statistic results of three individual devices. b Elastic modulus of perovskite films deposited on SnO2 and SCAs-modified SnO2 films. c Tensile load–displacement response curves of the perovskites with or without SCAs modification. d Schematic illustration of tensile test of DCB specimens without or with CN-PTES modification.
