The Department of Chemistry congratulates Associate Professor David Ginger on his promotion to the rank of Professor, effective September 16, 2010. David Ginger studies the physical chemistry of nanostructured materials with potential applications in low-cost photovoltaics (solar cells that convert sunlight directly to electricity), energy efficient light-emitting diodes, and novel biosensors. His group studies conjugated polymers, semiconductor nanocrystal quantum dots, and plasmon resonant metal nanoparticles using both scanning probe microscopy and optical spectroscopy. His group is known for pioneering the development and application of scanning probe microscopy methods to understand how to improve nanostructured solar cells. For instance, by using a sharp metal probe to collect current from very small regions of a solar cell they can determine which regions give the most photocurrent–and which don’t. These experiments can be used to improve the manufacturing of thin film solar cells and to test basic theories of charge transport in disordered materials.
