Effect of hexamethylenetetramines (HMT) surfactant concentration on the performance of TiO2 nanostructure photoelectrochemical cells

Hexamethylenetetramine (HMT) surfactant was used to modify the morphology of TiO2 thin film nanostructure prepared by a simple technique, namely, liquid phase deposition (LPD) during its growth process. In order to obtain various surface morphologies of TiO2 nanostructures, the concentration of HMT...

In order to obtain various surface morphologies of TiO2 nanostructures, the concentration of HMT was varied from 10 to 100 mM.

The Jsc of the cell increased with concentration of HMT. The cell utilizing the TiO2 nanostructure with the smallest grain size possessed the best interfacial contact at the TiO2/electrolyte containing iodide/triiodide redox couple.
