The McGehee group is currently doing research on perovskite solar cells as well as dynamic windows that have adjustable tinting. This research builds on our prior investigations of organic light-emitting diodes and lasers, light extraction from LEDs, light trapping in solar cells, charge transport in organic semiconductors, nanopatterning, organic and dye-sensitized solar cells and semi-transparent electrodes based on meshes of carbon nanotubes or silver nanowires. The group is inspired to develop technology that can provide humanity with clean energy and solve environmental problems. Although all of our projects have a clear application and we interact closely with companies, we take a fundamental scientific approach that involves sophisticated characterization and advanced modeling. Our current projects are described on our Research page, and our latest results are always posted promptly on the publications page.
