Metal Oxides and Their Composites for the Photoelectrode of Dye Sensitized Solar Cells

Abstract

Initially, the fi eld of composite materials concerns essentially the aerospace industry and other engineering applications. Due to their good mechanical characteristics in terms of stiff ness and strength coupled with mass-saving advantage and other at ractive physico-chemical properties, their use is seen to be growing rapidly and now extends in a wide range of various fi elds among them: medicine and nanotechnology. Some imaginable techniques towards the application of nanotechnology in medicine have become realities, where signi fi cant progress has been made in recent years. Other research studies including “innovative techniques” are still in their various stages of development.
