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

Two-Dimensional Material Tandem Detectors for Polarimetry and Spectroscopy. The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light. This topic is significant because it could overcome current cost/performance issues of tandem detectors, .... Two-Dimensional Material Tandem Detectors for Polarimetry and Spectroscopy. The aim of this project is to leverage the fundamental advantages that two-dimensional (2D) materials could provide to vertically-stacked (tandem) photodetectors. The strong absorption, tunable bandgap and polarisation dependence that many 2D materials exhibit, provides a means by which to detect properties of light. This topic is significant because it could overcome current cost/performance issues of tandem detectors, enabling widespread usage. The expected project outcome is the development of a novel tandem 2D detector, which as a single detector/pixel, can extract the intensity, polarisation and wavelength region of incoming light. This would provide benefits for many future applications, including machine vision and aerial surveying.Read moreRead less

Low explosive vapour concentration limits the efficacy of portable detectors. Current preconcentrator technologies sorb vapours but require heat to release the concentrated material limiting their use to non-portable detectors. This project is expected to deliver materials and a device module for a preconcentrator technology that will sorb explosive analytes, have low power requirements and be compatible with hand held explosives detectors.
