Recent demonstrations of increased efficiencies in polymer-fullerene blend plastic films provide the prospect of low cost photovoltaic elements with the potential for widespread application. Further progress with these materials is strongly indicated. We will characterise these materials at the nanoscale to make further improvements in film morphology and employ our expertise in experimental investigation of transport properties to gain a more complete understanding of the electronic and photonic processes underlying photovoltaic efficiency. Australia is ideally situated geographically and has a strong tradition of inventive engineering from which we can benefit and capitalise significantly on further improvements in the materials to be investigated.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
Advanced Ionic Materials for Organic Photovoltaics. Australia will greatly benefit from the development of improved solar energy technology, as a means of addressing the issue of climate change as a result of continued fossil fuel use. Solar power is also advantageous as it also allows electricity to be generated locally where it is needed, which is particularly important for the many remote areas of Australia. The climate in Australia is ideally suited for the electricity production through pho ....Advanced Ionic Materials for Organic Photovoltaics.

Solar power is also advantageous as it also allows electricity to be generated locally where it is needed, which is particularly important for the many remote areas of Australia. The climate in Australia is ideally suited for the electricity production through photovoltaics, and this project will focus on improving the performance of these devices to enable their widespread use.

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.

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
New Materials for Energy Capture and Conversion: Ionic Liquid-derived Conducting Polymers. Inherently conducting polymers (ICPs) have applications in a wide range of electrochemical devices including actuators, for artificial muscles, and photovoltaic cells for harnessing solar energy. Use of an ionic liquid as the electrolyte within these devices greatly increases the stability and cyclability of the ICP. Our preliminary work shows that an ionic liquid solvent in the synthesis of ICPs results i ....New Materials for Energy Capture and Conversion: Ionic Liquid-derived Conducting Polymers. Inherently conducting polymers (ICPs) have applications in a wide range of electrochemical devices including actuators, for artificial muscles, and photovoltaic cells for harnessing solar energy. Use of an ionic liquid as the electrolyte within these devices greatly increases the stability and cyclability of the ICP. Our preliminary work shows that an ionic liquid solvent in the synthesis of ICPs results in materials with dramatically different morphologies and improved electronic properties. Ionic liquids will be used to prepare ICPs with enhanced electrical and mechanical properties and prototype photovoltaic and actuator devices will be developed based on these new materials.Read moreRead less
