High‐Speed, Sensitive Planar Perovskite Photodetector Based on Interdigitated Pt and Au Electrodes

Abstract

Organic–inorganic hybrid perovskites are a new class of semiconducting materials currently yielding high‐performance solar cells. They are also attractive for fabrication of photodetectors, which are based on similar operating principles. Herein an easily producible perovskite photodetector with lateral architecture is reported fabricated by one‐step solution processing technique on planar interdigitated electrodes. Despite the simple structure, the planar photodetector demonstrates comparable, or even some superior characteristics to photodetectors based on a more complex architecture.
