From single molecules to dye-sensitized solar cells

Published on July 20, 2012

Dye-sensitized solar cells are a relatively new type of energy conversion system, which interlink the field of chemistry and physics.

Functionalized molecules are adsorbed onto a TiO2 nanostructured surface. When illuminated, these functionalized molecules provide charges to the conduction band of the TiO2 particles. Many aspects of the chemical, electrical, and geometrical properties of the adsorbed molecules are still unknown. We use high-resolution atomic force microscopy to characterize single molecules and molecular assemblies on such surfaces.

Thilo Glatzel is leader of the scanning probe microscopy group of Prof. Ernst Meyer at the University of Basel, Switzerland. His research is mainly focused on high-resolution atomic force microscopy, the development of new detection techniques, Kelvin Probe Force Microscopy, and the analysis of single molecules and structures on insulating surfaces and other nanostructured samples, such as hexagonal graphene and boron nitride. Recently, he started developing and characterizing dye-sensitized solar cells based on natural dyes.

Rémy Pawlak is a postdoc in the scanning probe microscopy group and manipulates and characterizes single molecules at low temperatures by means of tuning-fork-based atomic force microscopy.

Gregor Fessler is a PhD student in the scanning probe microscopy group and develops a new ultrahigh-vacuum atomic force microscope that facilitates high-resolution friction and dissipation measurements.
