研究目的
To study the effect of Fe doping on some physical properties of ZnO sprayed thin films.
研究成果
Fe-doped ZnO thin films prepared by spray pyrolysis technique show promising structural, optical, and electrical properties for applications in optical devices such as solar cells. The best electrical resistivity was achieved with 3% Fe doping.
研究不足
The study is limited to the effects of Fe doping up to 20% on ZnO thin films prepared by spray pyrolysis. Potential areas for optimization include exploring higher doping concentrations and alternative deposition techniques.
