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 expects to boost the efficiency of silicon solar cells by adding a low-cost solar cell on top to create a tandem d ....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 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 science and engineering of defects and impurities in photovoltaic silicon. This project will create the knowledge and techniques that are essential to make low-cost, impure silicon suitable for producing highly efficient solar cells. This will help to drive down the cost of solar electricity, since the silicon material itself is a significant component of the overall cost of most photovoltaic modules.
Designing reactivity of homogeneous and heterogeneous water-splitting catalysts using muti-dimensional site-selective spectroscopies. New classes of heterogeneous manganese-calcium water splitting catalysts analogous to the unique biological water splitting cofactor have recently emerged but with far lower catalytic rates than seen for the biological system. These new materials are promising targets for large-scale hydrogen fuel production with low cost, high efficiency and ease of manufacture. ....Designing reactivity of homogeneous and heterogeneous water-splitting catalysts using muti-dimensional site-selective spectroscopies. New classes of heterogeneous manganese-calcium water splitting catalysts analogous to the unique biological water splitting cofactor have recently emerged but with far lower catalytic rates than seen for the biological system. These new materials are promising targets for large-scale hydrogen fuel production with low cost, high efficiency and ease of manufacture. To achieve this, the performance gap between these materials and the homogenous biological catalyst must be bridged. Multi-dimensional site-selective spectroscopies, including magneto/optical resonance methods which are aimed to be developed in this project are expected to provide new, atomic level understanding of properties needed to achieve high catalytic efficiency, thus guiding rational catalyst design.Read moreRead less
Nanophotonic tandem designs for high efficiency solar cells. This project will develop high-efficiency tandem solar cells that combine established silicon cell technology with novel low-cost thin-film solar cells. It will incorporate nanostructured layers between the cells that selectively trap different wavelengths of light, maximising light absorption in the top cell. This will make it possible to use a very thin top cell, reducing the requirements on electronic quality of the material. This p ....Nanophotonic tandem designs for high efficiency solar cells.

It will incorporate nanostructured layers between the cells that selectively trap different wavelengths of light, maximising light absorption in the top cell. This will make it possible to use a very thin top cell, reducing the requirements on electronic quality of the material. This project will also develop self-assembly techniques to enable the new nanostructures to be fabricated quickly and cheaply but with a high degree of control. Such cells will allow open the door to higher efficiencies, and lower costs, than is achievable with conventional solar cells.Read moreRead less
Nanoscale control of energy and matter for future energy-efficient technologies. Unprecedented control of energy and matter in nanoscale fabrication will be achieved using non-equilibrium self-organised plasma-solid systems. The outcomes will lead to energy-efficient, environment- and human-health-friendly production of nanomaterials for future energy, health, information, food, water, environmental and security technologies.
