Abstract

Thin layer properties can be tailored based on the optimization of the precursor system and the deposition technique and parameters. For large surface – area applications, appropriate reproductible deposition must be chosen.

Tungsten trioxide presents remarcable optoelectric properties making it an ideal candidate as photoanode in a photo-electrochemical cell (PECC), [1-3].

This paper provide a comparative approach on WO3 thin layers obtained via spray pyrolysis deposition (SPD) and other state-of-art deposition techniques. The influence of the SPD parameters (precursor system and temperature) on the thin WO3 films with different crystalline properties, morphology and surface tension were considered.
