Abstract

The present project proposes to develop and assess the performance of different electrode nanostructures applied in solar energy conversion (dye-sensitized solar cell) and biosensors devices. These devices, based on semiconducting-oxide nanostructures, will be characterized by traditional electrochemical techniques. In addition, Electrochemical Impedance Spectroscopy technique will be used to aid the improvement of new technologies.
