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

III-V semiconductor nanowire solar cells without p-n junctions. This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation. Instead the band structure of the semiconductors is engineered to form a misalignment which leads to the spatial separation of carriers.

This project proposes a new class of nanowire solar cells that do not rely on conventional electrical (p-n) junction for photo-generated charge carrier separation. Instead the band structure of the semiconductors is engineered to form a misalignment which leads to the spatial separation of carriers. This approach is expected to fundamentally change the design of solar cells, eliminating the technologically challenging need for forming good electrical junctions, while retaining all advantages inherent to III-V semiconductor nanowire solar cells. More importantly, the device concept proposed is expected to have implications for a wider class of solar cells based on exotic/novel materials or nanostructures where achieving both n- and p-doping may be challenging.Read moreRead less

This project aims to realise rapid fabrication of controllable nano-devices over large areas with high throughput and low cost. The lack of large-size (greater than four inch) mask and ultra-low dose resist are the fundamental challenges for high-throughput radioisotope-powered parallel electron nano-lithography (RIPEL) systems. This project aims to realise a large-size RIPEL mask by using the ultra-light supporting material aerographite that has a state-of-the-art ratio value of Young's modulus to cubic density. It will also develop a new inorganic nanoparticle resist with ultra-low dose. These building blocks will enhance RIPEL's throughput by four orders of magnitude. The project will contribute to making processors or solid state storage cheaper and more efficient.Read moreRead less
