Vanadium-based electrode for perovskite photoelectric device, and perovskite photoelectric device prepared by using vanadium-based electrode

Abstract

Provided is a vanadium-based electrode for a perovskite-based optoelectronic device, and a perovskite-based optoelectronic device fabricated using the same. The vanadium-based electrode for the perovskite-based optoelectronic device is a vanadium electrode or a vanadium-pure metal/alloy composite electrode formed by magnetron sputtering on a back side of the perovskite-based optoelectronic device. The vanadium electrode or the vanadium-alloy electrode is suitable for optoelectronic devices with perovskite layers. In this application, a vanadium metal or a multilayer composite structure including vanadium, copper, etc. is fabricated on a perovskite solar cell to produce a vanadium-based electrode. The vanadium-based electrode can enhance the stability of the perovskite solar cell and reduce the cost of the perovskite solar cell, which creates great potential for large-scale production of perovskite solar cells. Compared with the prior art, this application offers advantages such as simplicity, practicality, and suitability for industrialization.
