Transparent Conducting Oxides (TCOs)
p-type TCOs
Our largest research project in the field of TCOs concerns hole conducting transparent (semi)conducting oxides. Such p-type TCOs are much sought after for fully transparent oxide electronics and can also help to improve efficiencies of solar cells and LEDs.
The performance of well known p-type TCOs is still rather poor. In the group we investigate a new, promising material based on Cr2O3. In particular we are interested in:
- Doping and conduction mechanisms in p-type TCOs
- Investigations of correlation of growth conditions to optical and electrical properties
- Applications of p-type TCOs in organic photovoltaic solar cells
- Fundamental investigations of interface formation in fully transparent p-n junctions
Modified n-type TCOs
We also investigate ways to modify some core properties of well known n-type TCOs such as SnO2:F (FTO) and ZnO:Al (AZO) in terms of refractive index modifications, band gap engineering, and optical scattering properties (haze). Our work includes:
- Elemental substitution to alter the optical properties of such TCOs
- Investigations of novel layered structures for effective medium materials
