RESEARCH INTERESTS-10 SELECTED ISI PUBLICATIONS (OF A TOTAL OF 69 PEER-REVIEWED
ARTICLES)
My research is focus on the improvement of the interfaces between the active component (e.g.,
organic semiconductor) and the electrode materials at organic photovoltaics (OPVs), organic light
emitting diodes (OLEDs) and, recently, on perovskite solar cells by modifying these interfaces with
metallic oxides of various stoichiometries, with molecular oxides, porphyrin compounds, by
altering the polarity of the interfaces etc. The main purpose of my work is to achieve high devices
efficiencies and environmental stability and to develop of an understanding of the main physical
processes that influence devices efficiency and stability, which represents a major challenge in the
field of green photovoltaic technologies, in general.
