  2. Device physics and working principles of polymer solar cells, with the aims of developing the next generation architectures with increased efficiency (PhD positions available)
  3. Transient absorption, photo-CELIV, charge extraction and mobility measurements of organic solar cell materials
  4. Intensity modulated voltage and current spectroscopy, electrochemical impedance spectroscopy of organic solar cells (PhD positions available)
  5. Porphyrin-sensitised liquid and dye-sensitised solid state dye-sensitised solar cells (PhD positions available)
  6. Photoelectrochemical hydrogen generation and water splitting.

My expertise is organic solar cell fabrication and advanced characterisation using time-resolved and frequency-modulated optical and electrical probes. This expertise covers the two main areas of organic photovoltaic research: polymer/fullerene bulk heterojunction (plastic) solar cells and dye-sensitised solar cells.

My main research focus till 2015 is to develop new architectures for donor/acceptor type organic solar cells. The main goal is to the break their fundamental efficiency limit, currently predicted to peak at around 10 – 11% in the next couple of years. This research is funded by an Australian Research Council Discovery Project.

Since 2010 my together with my colleague Dr Tracey Clarke we have been working with Konarka Technologies, a world-leading plastic solar cell manufacturing company located in Lowell, MA in the USA. This work is sponsored by the industry partner and an Australian Research Council Linkage Project. Our main contribution is to use our experimental techniques and expertise to understand the factors governing charge generation, transport and recombination in donor/acceptor blends. These processes have a direct impact on the manufacturing of these low-cost solar cells.

Since 2002, I have been studying charge transport and recombination processes in both dye-sensitised and polymer/fullerene type solar cells using time-resolved charge extraction, transient absorption, and frequency modulated (electrochemical impedance / intensity modulated voltage spectroscopy) techniques. My most important contribution was the development of the photo-induced charge extraction by linearly increasing voltage technique to simultaneously determine charge mobility and recombination in plastic solar cells. This technique has become the “industry” standard, evidenced by the large number of citations and a commercialisation effort to develop a turn-key measurement setup. The highlights of my work on the dye-sensitised solar cells include publications in Nature Materials, two first author communications in the Journal of the American Chemical Society and a first author article in Chemical Communications. In 2010, our team was awarded a Discovery Project to build on this expertise and to develop multi-chromophore porphyrin sensitisers for ultra-thin dye-sensitised solar cells.

Since 2010 we have made important discoveries in photoelectrochemical water splitting.
