Improving electrical performance of ultrasonic spray pyrolysis grown textured ZnO films by introducing In2O3:W interface layer

- Using W doped In2O3 (IWO) as interface layer, IWO/ZnO films were prepared.
- IWO/ZnO films show close to 50 cm2 V s−1 high Hall mobility.
- IWO/ZnO films indicate 80% high transparency in 400-2000 nm (including glass).
- IWO/ZnO films show high haze factor and root-mean square roughness.
