This project will investigate the use plasmonic absorption of light in metal nanostructures to activate the selective oxidation/reduction of a gas molecule on a semiconductor nanoparticle. This concept will be used with the aim of developing a sensing technique capable of measuring ultra-low concentrations (ppb) of breath markers for lung cancer detection. It is expected that porous sensing films of semiconductor and metal nanoparticles with well-defined light absorption properties will be fabricated. Superior selectivity will be achieved by matching the wavelength of the absorbed light with the required activation energy for oxidation/reduction. Successful outcomes will enable multi-analyte fingerprint identification by on-chip devices with applications ranging from portable medical diagnostics to national security.Read moreRead less

The project seeks to develop high performance photoferroelectric materials for a wide range of photoenergy conversion technologies like photovoltaics and photocatalytics. For the past 50 years, ferroelectric photovoltaics have only been an academic curiosity due to their low energy conversion efficiency relative to the popular semiconductor photovoltaics. This project aims to unlock the potential of ferroelectric photovoltaics by introducing an ion co-substitution, which is coupled with electron-pinning, into promising ferroelectric materials and investigating the resultant photo-excited electronic and electrical properties. It is anticipated that the outcomes from this proposed project will provide a solution for optimal ferroelectric visible light absorption to achieve high power conversion efficiency in ferroelectric materials for practical photoenergy applications.Read moreRead less

Perovskite-silicon tandem solar cells: a pathway to 30 per cent efficiency. This project aims to develop a new type of solar cell that is much more efficient than today’s commercial silicon solar cells. Increasing cell efficiency is one of the most effective ways to reduce the cost of solar electricity, but silicon cells are approaching practical and theoretical limits.

This project aims to develop a new type of solar cell that is much more efficient than today’s commercial silicon solar cells. Increasing cell efficiency is one of the most effective ways to reduce the cost of solar electricity, but silicon cells are approaching practical and theoretical limits. This project expects to boost the efficiency of silicon solar cells by adding a low-cost solar cell on top to create a tandem device. The expected outcome is a solar cell that can convert more than 30 per cent of incident sunlight into electricity, compared to 20-25 per cent for current cells. Developing cheap, high efficiency solar cells should further reduce the cost of solar electricity, and accelerate the uptake of clean energy.Read moreRead less

The project aspires to develop a scalable low-cost approach for the synthesis and integration of ultra-porous films in nanodevices. The project intends to deposit atomic layers onto aerogel-like nanoparticle networks, self-assembled by thermophoresis of flame-made aerosols. This would increase the atomically-deposited layer mass by several hundred-fold per cycle and result in ultra-porous films with electrochemically active surface areas. It is intended that the project will demonstrate the fabrication of solid–gas, solid–liquid and solid–solid nanointerfaces, which will be applicable to key emerging technologies such as wearable medical diagnostics.Read moreRead less
