A High-Performance UVA Photodetector Based on Polycrystalline Perovskite MAPbCl<sub<3</sub</TiO<sub<2</sub< Nanorods Heterojunctions

The application of TiO<sub<2</sub< nanorods in the field of ultraviolet (UV) photodetectors is hindered by a high dark current, which is attributed to crystal surface defects and intrinsic excitation by carrier thermal diffusion. Here, a photodetector based on polycrystalline perovskite...

Here, a photodetector based on polycrystalline perovskite MAPbCl<sub<3</sub</TiO<sub<2</sub< nanorods heterojunctions has been fabricated to overcome the shortcoming. The structure was composed of horizontal MAPbCl<sub<3</sub< polycrystalline and vertically aligned TiO<sub<2</sub< nanorods array. Many localized depletion regions at the MAPbCl<sub<3</sub</TiO<sub<2</sub< interface can reduce the dark current. The TiO<sub<2</sub</MAPbCl<sub<3</sub< 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 TiO<sub<2</sub< detector. This study indicates the potential in the TiO<sub<2</sub</MAPbCl<sub<3</sub< heterojunction to fabricate high-performance UV detectors.

Here, a photodetector based on polycrystalline perovskite MAPbCl<sub<3</sub</TiO<sub<2</sub< nanorods heterojunctions has been fabricated to overcome the shortcoming. The structure was composed of horizontal MAPbCl<sub<3</sub< polycrystalline and vertically aligned TiO<sub<2</sub< nanorods array. Many localized depletion regions at the MAPbCl<sub<3</sub</TiO<sub<2</sub< interface can reduce the dark current. The TiO<sub<2</sub</MAPbCl<sub<3</sub< 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 TiO<sub<2</sub< detector. This study indicates the potential in the TiO<sub<2</sub</MAPbCl<sub<3</sub< heterojunction to fabricate high-performance UV detectors. polycrystalline perovskite MAPbCl<sub<3</sub< TiO<sub<2</sub< nanorods heterojunction dark current UV photodetector Chemical technology Yannan Zhai verfasserin aut Hui Zhang verfasserin aut Zhaoxin Wang verfasserin aut Yongfeng Zhang verfasserin aut Ruiliang Xu verfasserin aut Shengping Ruan verfasserin aut Jingran Zhou verfasserin aut In Sensors MDPI AG, 2003 23(2023), 15, p 6726 (DE-627)331640910 (DE-600)2052857-7 14248220 nnns volume:23 year:2023 number:15, p 6726 https://doi.org/10.3390/s23156726 kostenfrei https://doaj.org/article/5f1e0588e8044f6394ab736788789cb2 kostenfrei https://www.mdpi.com/1424-8220/23/15/6726 kostenfrei https://doaj.org/toc/1424-8220 Journal toc kostenfrei GBV_USEFLAG_A SYSFLAG_A GBV_DOAJ GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_39 GBV_ILN_40 GBV_ILN_60 GBV_ILN_62 GBV_ILN_63 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_95 GBV_ILN_105 GBV_ILN_110 GBV_ILN_151 GBV_ILN_161 GBV_ILN_170 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_602 GBV_ILN_2005 GBV_ILN_2009 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2055 GBV_ILN_2057 GBV_ILN_2111 GBV_ILN_2507 GBV_ILN_4012 GBV_ILN_4037 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4249 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4325 GBV_ILN_4335 GBV_ILN_4338 GBV_ILN_4367 GBV_ILN_4700 AR 23 2023 15, p 6726

abstract	The application of TiO<sub<2</sub< nanorods in the field of ultraviolet (UV) photodetectors is hindered by a high dark current, which is attributed to crystal surface defects and intrinsic excitation by carrier thermal diffusion. Here, a photodetector based on polycrystalline perovskite MAPbCl<sub<3</sub</TiO<sub<2</sub< nanorods heterojunctions has been fabricated to overcome the shortcoming. The structure was composed of horizontal MAPbCl<sub<3</sub< polycrystalline and vertically aligned TiO<sub<2</sub< nanorods array. Many localized depletion regions at the MAPbCl<sub<3</sub</TiO<sub<2</sub< interface can reduce the dark current. The TiO<sub<2</sub</MAPbCl<sub<3</sub< 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 TiO<sub<2</sub< detector. This study indicates the potential in the TiO<sub<2</sub</MAPbCl<sub<3</sub< heterojunction to fabricate high-performance UV detectors.

Here, a photodetector based on polycrystalline perovskite MAPbCl<sub<3</sub</TiO<sub<2</sub< nanorods heterojunctions has been fabricated to overcome the shortcoming. The structure was composed of horizontal MAPbCl<sub<3</sub< polycrystalline and vertically aligned TiO<sub<2</sub< nanorods array. Many localized depletion regions at the MAPbCl<sub<3</sub</TiO<sub<2</sub< interface can reduce the dark current. The TiO<sub<2</sub</MAPbCl<sub<3</sub< 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 TiO<sub<2</sub< detector.
