Optimization of surface morphology and scattering properties of TCO/AIT textured glass front electrode for thin film solar cells

- Aluminium induced texture (AIT) method has been used for obtaining highly textured glass substrates.
- The effect of wet etch step on morphological and optical properties has been analyzed.
- The morphology features have been optimized in order to obtain the best scattering properties.
- Different ZnO surface textures, depending on the underlying glass substrate structures, are obtained.
- The effect of different glass texture on optical confinement has been tested in a-Si:H devices.
