The main objective of my project is the synthesis, characterization and investigation of innovative photoanodes for dye sensitized solar cells using CNTs/TiO2 and graphene/TiO2 composites.

A second project deals with the integration of colloidal quantum dots (QDs) in a flat cell geometry including proper modulation of electronic band alignment of the various components of the solar cell, including PbS and core-shell PbS-CdS QDs, ITO glass, CdS thin film and aluminum electrode.

A series of experimental techniques will be applied for materials characterization, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), scanning tunneling microscopy (STM), atomic force microscopy (AFM), x-ray diffraction (XRD).
Solar cell fabrication and testing is planned aiming at understanding the role of the new nanomaterials in the determination of the photovoltaic behavior of the solar cells.

Education:
General university diploma in Applied Physics in Tianjin University, China July 2012.
