Abstract:Flexible
devices have aroused great interest due to their potential
for wearable and portable applications. In this paper, the [001]-oriented
all-inorganic perovskite CsPbBr3 films were grown on a
flexible polyimide substrate, and the corresponding flexible self-powered
photodetectors (PDs) were prepared. The [001]-oriented CsPbBr3 films have an atomically flat surface and a low defect density.
Under zero bias voltage and 405 nm irradiation, the flexible PD presents
a responsivity of 151.9 mA W–1 and a specifi… Show more
