Photoactive Semiconducting Biopolymers. The basic aims of this project are to elucidate, manipulate, and utilise the unique chemical and physical properties of a class of biopolymers called the melanins. These materials are the only known solid state semiconducting biopolymers, and are non-toxic, biocompatible, and biodegradable. Their use as active components in biomimetic soft electonic, optoelectronic or photovoltaic devices, has not hitherto been demonstrated. It is anticipated that the k ....Photoactive Semiconducting Biopolymers.

These materials are the only known solid state semiconducting biopolymers, and are non-toxic, biocompatible, and biodegradable. Their use as active components in biomimetic soft electonic, optoelectronic or photovoltaic devices, has not hitherto been demonstrated. It is anticipated that the key outcomes from the project will be a demonstration of biopolymer-based photoelectrochemical and solid-state p-i-n solar cells, and an improved understanding of the physics and chemistry of these important biological macromolecules.Read moreRead less
Fabrication of High Performance Nanocomposite Photoanodes with Built-in Electron Transport Superhighway for Photoelectrocatalysis Applications. Worldwide, huge fresh water shortage problems force us to recycle/reuse water. For Australia, this is an urgent issue due to our limited fresh water resources. In recent years, rapidly diminishing fossil fuel supplies and dramatically accelerated global warming gives society no alternative but adopt renewable, clean energies. Globally, there is a united ....Fabrication of High Performance Nanocomposite Photoanodes with Built-in Electron Transport Superhighway for Photoelectrocatalysis Applications. Worldwide, huge fresh water shortage problems force us to recycle/reuse water. For Australia, this is an urgent issue due to our limited fresh water resources. In recent years, rapidly diminishing fossil fuel supplies and dramatically accelerated global warming gives society no alternative but adopt renewable, clean energies. Globally, there is a united front calling for action to address these problems. However, a practical solution to the issues can only be found when economically viable alternative technologies are developed. This project aims to tackle the biggest obstacle - the low sunlight conversion efficiency. The success of the project will result in economically viable water treatment and solar energy conversion technologies. Read moreRead less
Naturally Photoactive Biopolymers. The basic aim of this project is to assess the viability of using semiconducting biopolymers from the melanin family of macromolecules in photoactive device based applications. In order to do this, key optical, structural, electronic, and photochemical properties will be assessed on thin films in the solid state. The melanins are the only known semiconducting biopolymers, and are non-toxic, biocompatible and biodegradable. Their use as ?active? materials in ....Naturally Photoactive Biopolymers. The basic aim of this project is to assess the viability of using semiconducting biopolymers from the melanin family of macromolecules in photoactive device based applications. In order to do this, key optical, structural, electronic, and photochemical properties will be assessed on thin films in the solid state. The melanins are the only known semiconducting biopolymers, and are non-toxic, biocompatible and biodegradable. Their use as ?active? materials in solid state or photo-electrochemical devices has never before been suggested. Specifically, these materials could be used as the light harvesting components in dye sensitised Gratzel cells, or, as the donor material in soft solid photovoltaic junctions. The melanins are also a key class of biomolecules (their involvement in skin cancers is well documented), and hence, any advancement in our understanding of their functions and properties could have biological importance.Read moreRead less
Efficient Dye-Sensitised Solar Cells: New Cathodic Materials and Systems. Accelerating the uptake of renewable energy through new and diverse sources is critical to Australia's commitment to sustainable future, and Australia's energy security. This project will address key issues in commercially emerging Dye Solar Cell (DSC) technology, which has been accepted as a credible avenue to cost effective solar electricity. To date, significant development both in industry and Academia, has resulted in ....Efficient Dye-Sensitised Solar Cells: New Cathodic Materials and Systems. Accelerating the uptake of renewable energy through new and diverse sources is critical to Australia's commitment to sustainable future, and Australia's energy security. This project will address key issues in commercially emerging Dye Solar Cell (DSC) technology, which has been accepted as a credible avenue to cost effective solar electricity. To date, significant development both in industry and Academia, has resulted in Australia's leading and often pioneering position in this field. The project will maintain and enhance this position through both scientific and commercial outcomes, including opening up new markets for flexible DSC and exporting products and technological solutions through commercial activities of the Partner Organisation.Read moreRead less
