摘要

Abstract

The fast crystallization and facile oxidation of Sn

of tin-lead (Sn-Pb) perovskites are the biggest challenges for their applications in high-performance near-infrared (NIR) photodetectors and imagers. Here

we introduce a multifunctional diphenyl sulfoxide (DPSO) molecule into perovskite precursor ink to response these issues by revealing its strong binding interactions with the precursor species. The regulated perovskite film exhibits a dense morphology

reduced defect density and prolonged carrier diffusion length. The manufactured self-powered photodetector realizes a spectral response of 300-1100 nm

dark current density of 4.7 × 10

−8

mA cm

−2

peak responsivity of 0.49 A W

−1

and specific detectivity of 1.20 × 10

Jones in NIR region (780–1100 nm)

–3 dB bandwidth of 11.4 MHz

linear dynamic range of 174 dB

and ultrafast rise/fall time of 14.2/17.1 ns

respectively. We demonstrate a 64 × 64 NIR imager with an impressive spatial resolution of 1.32 lp mm

−1

by monolithically integrating the photodetector with a commercial thin-film transistor readout circuit.
