• high optical transmission also in the near IR spectral range
• defined surface morphology and work function for efficient light trapping and charge collection
• good thermal and chemical stability
• low-cost and low-temperature growth process.
Another set of functionalities is required for optical applications:
• high refractive index and low extinction coefficient
• high homogeneity
• low mechanical stress and high environmental stability.
Our studies aim at achieving the required multifunctionality in films of transparent conducting oxides (TCOs) for applications as TE (In2O3, SnO2 and ZnO) and in transition metal oxides, such as Nb2O5, Ta2O5, and HfO2 for optical applications.
