Sb2Se3microwires/ZnO nanoparticles heterojunction for high performances self-powered photodetector.
Self-powered photodetectors play a crucial role in technology, garnering attention for their diverse applications. However, most current models face challenges such as reliance on external power, complex fabrication, and inconvenient usability. Sb2Se3presents a promising solution for p-type semiconductors in photovoltaic cells, owing to ideal bandgap and excellent light absorption. In this study, Sb2Se3microwires (MWs) synthesized by hydrothermal method was modified with zinc oxide (ZnO) nanoparticles (NP) to create the Sb2Se3-MW/ZnO NP heterostructure, designed to build a highly efficient photodetector featuring interdigitated electrodes. The Sb2Se3-MW/ZnO NP device exhibits self-powered characteristics and strong photoresponse from 350 to 1000 nm, achieving a photoresponsivity of 120 mA W-1at 368 nm (1.21 mW cm-2), an on/off ratio of 257, and a peak detection rate of 8.93 × 1011Jones. This innovative heterostructure significantly broadens the light response range, proving that the Sb2Se3-MW/ZnO-NP heterojunction is a major step toward high-performance, self-powered optoelectronic devices.
期刊介绍：
The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
