Materials Science and Engineering
The O’Carroll Research Group is focused on nanoscale engineering of the efficiency and direction of light generating and light harvesting processes in photonic devices which employ organic polymeric semiconductor materials and plasmonic nanostructures. For light generating devices, plasmonic nanoantennas are investigated as a means to enhance the efficiency, rate and directionality of low luminescence quantum efficiency, high-mobility conjugated polymer materials such as the widely studied poly(3-hexylthiophene). This is an original approach to solving one of the main challenges associated with using organic materials in opto-electronic devices – i.e., high charge carrier mobility organic materials predominantly exhibit low luminescence quantum efficiency due to intermolecular interactions. For light harvesting devices such as bulk-heterojunction photovoltaics, nanostructured optically-active noble metal electrodes are designed and implemented to induce a number of beneficial photonic effects to the device behaviour that have the potential to push the technology closer to competitive solar power conversion efficiencies.
