Design and characterisation of 1-D titanium dioxide nanorod array as electron transport medium

Abstract This article summarises the design of one dimensional Titanium dioxide (TiO2) nanorod array and its compatibility as Electron Transport Medium (ETM) for Solar Cell Application. The approach followed for the growth of the one-dimensional nanostructures was template-free, one-step hydrothermal synthesis which is convenient for commercialization. A series of microscopic characterisation such as XRD, SEM and EDAX were carried out to analyse the structure and morphology of the prepared TiO2 array. The optical properties were determined using UV-DRS analysis. Field dependent dark and photoconductivity studies showed positive response confirming the effective photo conducting nature of the as-prepared samples. As a result, all these features validate the usage of one dimensional titanium dioxide array as efficient ETM in the fabrication of Solid State solar cells.
