We report herein a novel CH3NH3PbBr3 perovskite nanoflowers sensitized TiO2 photoanode for proficient PSCs. The TiO2 was grown hydrothermally and sensitized with CH3NH3PbBr3 material using spin coating method. The properties of the TiO2/CH3NH3PbBr3 have been studied using various characterisation techniques such as XRD, FESEM, EDAX, UV-DRS and Field dependent dark and photoconductivity. The structural properties revealed the surface coating of perovskite material with formation of novel three-dimensional nanoflower like structure on the top of TiO2. The UV-DRS spectroscopy indicated an increase in absorption upon sensitization of TiO2 with the CH3NH3PbBr3 perovskite material. An analysis of the elemental composition of the TiO2/CH3NH3PbBr3 showed high degree of purity of the sample. The transport properties of the samples were studied with Field dependent dark and photocurrent measurements which showed enhanced dark and photocurrent. The current work greatly supported the efficient sensitisation of TiO2 with CH3NH3PbBr3 perovskite nanoflowers and its potential for application as a high efficient photoanode material in PSCs.
