Excitonic Solar Cells-XSC

Our research is concentrated on the design and production of new excitonic solar cells, combining radically new materials with novel architectures.

Specific topics related to photovoltaic cells and nanotechnology are listed below:
- The interface and the interaction of hybrid Organic/ Inorganic Molecular Materials.
- Enhancing the efficiency of excitonic solar cells through the design of the working electrode.
- Design and control the inorganic sensitizer structure and properties in order to improve the PV parameters.
- New excitonic solar cells structures/architectures.

The FTIR Spectrum displays a shoulder at900 cm-1 which possibly indicates that Nb+ is in fact imbedded in the crystal structure of the TiO2 and is therefore a dopant and not a free entity.
This research concentrate on sensitizing of Nb+ doped TiO2 nanoparticles and their application in photovoltaics (i.e. dye sensitized solar cells). right shown TEM image of Nb+ doped anatase TiO2 nanoparticles with bipyramidalshape (up to ~ 30 nm diameter). Project Resposible: Ivan Tugov
