The project aims to develop next-generation organic-inorganic halide solar cells which are stable and non-toxic. Although rapid progress has been made in the emerging perovskite solar cell technology, it currently relies on lead as a key perovskite component. The elimination of lead from organic-inorganic halide perovskite solar cells would greatly increase their acceptance as an alternative thin film photovoltaic solution because of their low cost and non-toxic nature. The dearth of lead-free perovskite solar cell demonstrations and the relatively low conversion efficiencies demonstrated understate their potential. This project plans to improve understanding of their photovoltaic enabling attributes by characterising and modelling their optical and electrical properties. It then plans to apply new fabrication methods to develop lead-free solar devices.Read moreRead less

Wide bandgap cells will be fabricated and applied on top of the high efficiency silicon solar cells pioneered at The University of New South Wales. Colloidal nanoparticles offer tunable electronic bandgaps, low process temperatures and uniform size dispersions from industrially feasible processes. A simple modification eliminates direct series connections between stacked nanoparticle solar cells, greatly improving device performance. The immense potential of these advantages set target efficiencies for combined colloidal nanoparticle and high efficiency silicon tandem cells above 30 per cent.Read moreRead less
Nanophotonics for strong absorption in extremely thin solar cells: moving beyond silicon. This project will lead to the development of extremely thin solar cells made of novel low-cost materials, which would likely reduce the cost of photovoltaic technology. If the cost of photovoltaics was sufficiently low then it could have a major impact on reducing greenhouse gas emissions and pollution in Australia and worldwide.

III-V Semiconductor Nanowire Solar Cells. III-V semiconductors, proven as excellent photovoltaic materials, combined with unique properties of nanowires will be investigated as new materials for third generation high efficiency solar cells. It will lead to fundamental understanding of photovoltaic mechanisms in nanowires and demonstration of nanowire solar cells for future applications.
Hot carrier solar cells: new approaches and demonstration of devices. The hot carrier solar cell aims to capture a large fraction of energy from solar photons normally lost as heat. This will give much higher efficiencies, and allow fabrication of cheap high efficiency devices. This can be achieved by modifying the way electrons lose their energy as heat, by blocking the lattice vibrations which cause this loss.

This project seeks to develop a new technology which allows solar cells to harvest a broader range of light from the sun, including red and infrared light, to increase solar-to-electric conversion efficiency. It is proposed that this would be accomplished through a series of chemical reactions which allow electrical power to be generated either by conventional means or a multi-step process in which low energy light is ‘glued’ together. This is of interest in relation to emerging technologies such as dye-sensitised solar cells, which are low cost, architecturally appealing and amenable to flexible substrates. It is anticipated that this project will provide a means for substantial improvement in solar cell efficiencies.Read moreRead less
