Research interests

Professor Bagnall's primary research interests are in the development of opto-electronic semiconductor devices and systems. This has involved light-emitting devices but most recently has focussed on the development of high-efficiency photovoltaic devices and solar panels and systems. His most significant research contributions include the demonstration of the first room-temperature ZnO laser, the first demonstrations of optical activity of metallic and dielectric planar chiral metamaterials, and a range of nanostructured, biomimetic and plasmonic light-trapping schemes applied to photovoltaic devices. Increasingly his research interest is moving towards the integration and uptake of renewable energy systems. 


With increasing focus on project-based learning supported by on-line content delivery and formative assessment, Bagnall is seeking to ensure that a student’s everyday experience on campus is built around hands-on projects as individuals with unique skills and interests and within diverse interdisciplinary teams. With industry mentors, academic guides and a community that can provide informed and skilful technical assistance, school will increasingly become a rich and diverse community of entrepreneurial, problem-solving engineers.
