Tethering of molecular sensitizers on solar cell surfaces

Titanium dioxide is a semiconductor widely used in solar cells. To harness the energy of the solar spectrum, it is sensitised with dyes which are bound by single or dual tethers. Most commonly these anchors are carboxylate groups, however catecholates and hydroxamates are also reported as convenient and robust alternatives.

With this project we aim to provide a comparative study on the microscopic events that lead the different tethers to guide the adsorption of molecular dyes on model titania surfaces. Scanning tunnelling microscopy under ultra-high vacuum conditions and at a temperature range of 250 to 350 K will be used as a convenient tool to provide real-space information about the adsorption and diffusion of single and dual anchors on single crystal surfaces of titanium dioxide.
