Research Interests
The Ptasinska group effort is to develop realistic physicochemical mechanisms occurring at the interphase of water/semiconductor surfaces, with specific emphasis on energy-related materials. We use an advanced in situ technique, that enables us to explore the relationships between semiconductor electronic properties with local interfacial chemistry. This scientific approach offers better understanding of chemical reactivity at interfaces and aids in achieving higher photoconversion efficiency and stability of solar photovoltaic devices for hydrogen production.

Key Words
Surface Science, Semiconductors, In Situ Spectroscopy, Photovoltaics
