摘要

Transparent and flexible photodetectors hold great promise in next-generation portable and wearable optoelectronic devices. However, most of the previously reported devices need an external energy power source to drive its operation or require complex fabrication processes. Herein, designed is a semitransparent, flexible, and self-powered photodetector based on the integrated ferroelectric poly(vinylidene-fluoride-trifluoroethylene) (P(VDF-TrFE)) and perovskite nanowire arrays on the flexible polyethylene naphthalate substrate via a facile imprinting method. Through optimizing the treatment conditions, including polarization voltage, polarization time, and the concentration of P(VDF-TrFE), the resulting device exhibits remarkable detectivity (7.3 x 10(12) Jones), fast response time (88/154 mu s) at zero bias, as well as outstanding mechanical stability. The excellent performance is attributed to the efficient charge separation and transport originating from the highly oriented 1D transport pathway and the polarization-induced internal electric field within P(VDF-TrFE)/perovskite hybrid nanowire arrays.
