Zinc oxide (ZnO) is a piezoelectric material, and ZnO nanorods can be grown easily using solution-based methods with as-grown alignment of the crystal lattice. Thus, when strained, the nanorod arrays will generate a potential difference between their two surfaces, and as such can be used for mechanical energy harvesting. We developed a novel p-n junction based nanogenerator using a junction between ZnO nanorods and PEDOT:PSS, and have developed this to significantly increase the output voltage and power, and investigate its commercial potential.
We are investigating a range of novel oxide materials and composite systems for both powder-based photocatalysis, and as thin films for photo-electrocatalysis (PEC), focussing on solar fuel generation (artificial photosynthesis). Our particular focus is on the role of ferroelectric polarisation in photocatalysis, and how this can be used to enhance catalyst performance.
We are investigating alternative materials, material combinations and deposition methods for use in organo-lead halide perovskite solar cells. We use both solution-based synthesis and are also developing chemical vapour deposition methods for large-area deposition and treatment of perovskites.
We are collaborating with various groups to produce hybrid organic-inorganic and organic bulk heterojunction (BHJ) solar cells. We can produce a wide variety of nanostructured and thin film oxide materials with morphology and composition tuned to the required application.
We are investigating a wide variety of photovoltaic devices that utilise nanostructured oxide materials to produce a high surface area interface, including both liquid- and solid-state dye-sensitised solar cells (DSSCs), and both inorganic and organic (carbon-based) quantum dot-sensitised solar cells. We develop both the nanostructured photoanode materials as well as full device structures, and work with collaborators to investigate novel materials such as biomass-derived carbon dots.
