Abstract

Hydrothermally grown TiO2 nanorod (NR) photoelectrodes were prepared by sensitizing CdS quantum dots to improve visible light activity of the TiO2. The CdS-sensitized photoelectrodes were heat-treated to obtain enhanced performance of the photoelectrode under visible light. Furthermore, performance of the TiO2 NR-based photoanodes was compared with those made of TiO2 nanotubes (NTs). Photocurrent measurement and overall cell efficiency of the NR-based solar cells showed higher efficiency compared to NT-based solar cell.
