Here, a photodetector based on polycrystalline perovskite MAPbCl3\/TiO2 nanorods heterojunctions has been fabricated to overcome the shortcoming. The structure was composed of horizontal MAPbCl3 polycrystalline and vertically aligned TiO2 nanorods array. Many localized depletion regions at the MAPbCl3\/TiO2 interface can reduce the dark current. The TiO2\/MAPbCl3 detector shows high performance including a high ratio of light-dark current of about six orders of magnitude, which is much larger than that of the TiO2 detector. This study indicates the potential in the TiO2\/MAPbCl3 heterojunction to fabricate high-performance UV detectors.<\/jats:p>","DOI":"10.3390\/s23156726","type":"journal-article","created":{"date-parts":[[2023,7,28]],"date-time":"2023-07-28T02:10:45Z","timestamp":1690510245000},"page":"6726","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A High-Performance UVA Photodetector Based on Polycrystalline Perovskite MAPbCl3\/TiO2 Nanorods Heterojunctions"],"prefix":"10.3390","volume":"23","author":[{"given":"Yupeng","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Electronic Science & Engineering, Jilin University, 2699 Qianjin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yannan","family":"Zhai","sequence":"additional","affiliation":[{"name":"Aviation University of Air Force, 7855 Renmin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Zhang","sequence":"additional","affiliation":[{"name":"Aviation University of Air Force, 7855 Renmin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaoxin","family":"Wang","sequence":"additional","affiliation":[{"name":"Aviation University of Air Force, 7855 Renmin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongfeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Electronic Science & Engineering, Jilin University, 2699 Qianjin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruiliang","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of High Power Semiconductor Lasers, School of Science, Changchun University of Science and Technology, 7089 Wei-Xing Road, Changchun 130022, China"},{"name":"Changchun University of Science and Technology Chongqing Research Institute, 618 Liangjiang Road, Chongqing 130022, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengping","family":"Ruan","sequence":"additional","affiliation":[{"name":"College of Electronic Science & Engineering, Jilin University, 2699 Qianjin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingran","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Electronic Science & Engineering, Jilin University, 2699 Qianjin Street, Changchun 130012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1063\/1.2741128","article-title":"TiO2 based metal-semiconductor-metal ultraviolet photodetectors","volume":"90","author":"Xue","year":"2007","journal-title":"Appl.
