Research Interests

 

The TFPR group carries out research on:

- Chalcopyrite and related thin film semiconductors for PV applications. The group is able to prepare full operating thin film solar cells based on CuIn1-xGaxSe2 (CIGS) with efficiencies approaching 10%. In this context the group grows and characterizes all the layers needed: Mo/CIGS/CdS/i-ZnO/ZnO:Al or ITO. For the growth of the CIGS layer the group has developed a unique method combining evaporation with RF-magnetron sputtering;

- The development of Cu2ZnSn(S1-xSex)4 (CZTS) as In free absorbers for thin film solar cells;

- The development of Dye Sensitised Solar Cells (DSSCs) with efficiencies 9.6%;

- The development of mini-modules based on DSSCs;

- The development of Third Generation solar cells like hybrid bulk heterojunction solar cells based on ZnO, TiO2 nanostructures, carbon nanotubes and P3HT;

- New materials and new concepts for solar cells:

- New absorbers for thin film solar cells (ex: SnS, CTS, etc.);

- New dyes for DSSCs in collaboration with LNEG and the Chemistry department, University of Aveiro;

- DSSCs with carbon nanotube forests and ZnO tetrapods.

 

Other interests of the group are:

 

- Development of growth and characterization equipment for semiconductors;

- Renewable Energies:

- Solar Thermal Energy;

- Concentrating systems;

- PV systems.

- Semiconductor devices in general;

- Fuel Cells.
