CsPbI3 nanorods as the interfacial layer for high-performance,all-solution-processed self-powered photodetectors

引用

Journal of Materials Science & Technology 2021年第16期75卷 196-204页

作者： muhammad imran Saleem Shangyi Yang Attia Batool muhammad Sulaman Chandrasekar Perumal Veeramalai Yurong Jiang Yi Tang Yanyan Cui Libin Tang Bingsuo Zou Beijing Key Laboratory of Nanophotonics and Ultrafine Optoelectronic Systems Center for Micro-Nanotechnology School of Physics Key Laboratory of Advanced Optoelectronic Quantum Design and Measurement Ministry of Education Beijing Institute of Technology Kunming Institute of Physics Research Center for Materials Science Beijing Institute of Technology Beijing Key Laboratory for Precision Optoelectronic Measurement Instrument and Technology School of Optics and Photonics Beijing Institute of Technology

Heterojunction is regarded as a crucial step toward realizing high-performance devices, particularly,forming gradient energy band between heterojunctions benefits self-powered photodetectors. Therefore, in this paper, the synthesis of CsPbInanorods(NRs) and its application as the interfacial layer in high-performance, all-solution-processed self-powered photodetectors are presented. For the bilayer photodetector ITO/ZnO(100 nm)/PbS-TBAI(150 nm)/Au, a responsivity of 3.6 A/W with a specific detectivity of 9.8 × 10Jones was obtained under 0.1 mW/cm~2 white light illumination at zero bias(*** self-powered mode). Meanwhile, the photocurrent was enhanced to an On/Off current ratio of 105 at zero bias with an open circuit voltage of 0.53 V for trilayer photodetector ITO/ZnO(100 nm)/PbSTBAI(150 nm)/CsPbI(250 nm)/Au, in which the CsPbINRs layer works as the interfacial layer. As a result, a specific detectivity of 4.5 × 10Jones with a responsivity of 11.12 A/W was obtained under0.1 mW/cm~2 white light illumination, as well as the rising/decaying time of 0.57 s/0.41 s with excellent stability and reproducibility upto four weeks in air. The enhanced-performance is ascribed to the mismatch bandgap between PbS-TBAI/CsPbIinterface, which can suppress the carrier recombination and provide efficient transport passages for charge carriers. Thus, it provides a feasible and efficient method for high-performance photodetectors.
