Our research is in the area of materials chemistry and physics of complex, soft materials. Specifically, we are interested in electrically-active polymeric and molecular materials.  We hope to elucidate the fundamental processing-structure-property relationships that govern these materials to generate design rules and guidelines for the rational synthesis of materials with tailored properties and the development of innovative processing and patterning technologies for the realization of low-cost, light weight, mechanically flexible thin-film devices, such as organic transistors and solar cells.

Currently, we are examining how specific processing conditions affect the structure evolution of organic and polymer materials, and how structure development can in turn impact applications-relevant macroscopic electrical and physical properties. Work is being carried out on functional block copolymers, solution-processable organic and polymeric conductors and semiconductors, as well as conjugated self-assembled monolayers.

Donor-Acceptor Interfacial Interactions Dominate Device Performance in Hybrid P3HT-ZnO Nanowire-Array Solar Cells

The adsorption of phosphonic acid derivatives on vertically oriented ZnO nanostructures modulates surface properties.  Subsequent infiltration of a polymer donor creates hybrid organic-inorganic solar cells whose device performance can be optimized through the adsorption of different phosphonic acid derivatives at the donor-acceptor interface. To learn more, refer to Luisa Whittaker Brooks' recent publication in Advanced Energy Materials.
