Research Interests

Dr Bremner’s work focuses on the development of advanced concept high efficiency photovoltaic devices. These advanced concepts promise energy conversion efficiencies greatly in excess of those available today, promising much lower costs due the lower number of solar cells required. His work spans looking at the theoretical basis of such advanced concepts, through to the experimental and ultimately industrial realization of devices based on these advanced concepts. A large part of his work is looking at the growth of semiconductor nanostructures, such as quantum wells and quantum dots, through Molecular Beam Epitaxy (MBE). The properties of the samples grown are studied through such techniques as photoluminescence and X-ray diffraction. The research undertaken combines the very latest in thinking on high efficiency photovoltaics and breakthroughs in materials fabrication and measurement.
