Career Summary

Biography

Research Expertise
I am a synthetic organic chemist with 10 publications and two international patents in the areas of conducting polymers, organic photovoltaic devices and the development of new materials for inclusion into these devices and have been responsible for the establishment of successful multidisciplinary collaborations with Nobel Laureate and conducting polymer chemist Prof. Alan MacDiarmid and physicist A/Prof. Paul Dastoor in areas directly applicable to this application. The patent held in conjunction with Prof. MacDiarmid, covers the preparation and processing of conducting polymers, a major consideration in the use of these materials in organic devices where often costly and time consuming methods are required. This contribution led to my employment in 2005 with A/Prof. Dastoor at the University of Newcastle studying the effect of incorporating porphyrin dye materials into conventional organic photovoltaic devices. This research has significantly improved the understanding of how devices of this type function. The work led to a patent covering the fabrication of multicomponent organic photovoltaic devices of the type which will be built and examined within this project and has highlighted the critical need to control the morphology of materials within these devices if significant advances are to be made in efficiency. As a result I have recently become active in the development and use of Scanning Transmission X-Ray Microscopy (STXM), Near-field Scanning Photocurrent Microscopy (NSPM) and other techniques to study the morphology of materials and relate this characteristic to key properties such as charge mobility and photocurrent generation within them. Utilising the expertise and skills developed in these studies I am now developing new organic field effect transistors for use as biosensors and extending my understanding of these materials to organoelectronics in general. The current project is the logical extension of my career to date, recognising the need to control the morphology of the materials within organoelectronic devices and directly addressing this need. Recognition of my contribution to the field came at the beginning of 2007 when I was appointed as a lecturer in chemistry at the University of Newcastle within the new Priority Research Centre for Organic Electronics.

Teaching Expertise
During my years working I have developed experience teaching chemistry at up to 3000 level, in particular at Massey University where I developed and taught the 123:318 Advanced NMR Spectroscopy course for three years (12 lectures and associated labs and tutorials, 2002-4) and undertook relief teaching for 123:314 Physical Chemistry. At various times, when required, I taught Organic Chemistry, Inorganic Chemistry and a 4000 level Supramolecular Chemistry course. In my current position as Lecturer of Chemistry at the University of Newcastle I am teaching into the 2nd year Organic Chemistry course (CHEM2310), 3rd year Molecular Organic Synthesis (CHEM3310) and 3rd year Environmental Chemistry (CHEM3610).

Abstract Scanning transmission X-ray microscopy (STXM) compositional mapping has been used to probe the mesomorphology of nanoparticles (NPs) synthesized from two very different polymer:fullerene blends: poly(3-hexylthiophene) (P3HT): phenyl-C61-butyric acid methyl ester (PCBM) and poly[4,8-bis(2-ethylhexyloxy)benzo(1,2-b:4,5-b')dithiophene-alt-5, 6-bis(octyloxy)-4,7-di(thiophen-2-yl)(2,1,3-benzothiadiazole)-5,5'-diyl] (PSBTBT): PCBM. The STXM data shows that both blends form core-shell NP structures with similar shell compositions, but with different polymer:fullerene ratios in the core regions. P3HT:PCBM and PSBTBT:PCBM NP organic photovoltaic (OPV) devices have been fabricated and exhibit similar device efficiencies, despite the PSBTBT being a much higher performing low band gap material. By comparing the measured NP shell and core compositions with the optimized bulk hetero-junction (BHJ) compositions, we show that the relatively higher performance of the P3HT:PCBM NP device arises from the fact that its shell composition is much closer to the optimal BHJ value than that of the PSBTBT:PCBM NP device.

Nanoparticulate zinc oxide can be prepared at low temperatures from solution processable zinc acetylacetonate. The use of this material as a cathode interfacial layer in nanoparticulate organic photovoltaic devices results in comparable performances to those based on reactive calcium layers. Importantly, the enhanced degradation stability and full solution processability make zinc oxide a more desirable material for the fabrication of large area printed devices. © 2014 AIP Publishing LLC.

Here, we report the development of an organic thin film transistor (OTFT) based on printable solution processed polymers and employing a quantum tunnelling composite material as a sensor to convert the pressure wave output from detonation transmission tubing (shock tube) into an inherently amplified electronic signal for explosives initiation. The organic electronic detector allows detection of the signal in a low voltage operating range, an essential feature for sites employing live ordinances that is not provided by conventional electronic devices. We show that a 30-fold change in detector response is possible using the presented detector assembly. Degradation of the OTFT response with both time and repeated voltage scans was characterised, and device lifetime is shown to be consistent with the requirements for on-site printing and usage. The integration of a low cost organic electronic detector with inexpensive shock tube transmission fuse presents attractive avenues for the development of cheap and simple assemblies for precisely timed initiation of explosive chains.

The impact of a calcium interface layer in combination with a thermal annealing treatment on the performance of poly(3-hexylthiophene) (P3HT):[6,6]-phenyl-C61-buteric acid methylester (PCBM) nanoparticle photovoltaic devices is investigated. Annealing is found to disrupt the microstructure of the nanoparticle active layer leading to a reduction in fill factor. However, X-ray photoelectron spectroscopy measurements show that the calcium interface layer causes PCBM to preferentially migrate to the cathode interface upon annealing, resulting in better charge extraction from the PCBM moiety, an increase in the built-in voltage, open-circuit voltage, and power conversion efficiency. Moreover, the annealing trends could be completely explained by the observed PCBM migration. Unlike P3HT:PCBM bulk heterojunction devices, the P3HT:PCBM nanoparticle devices showed a remarkable thermal stability up to 120°C. As such, OPVs fabricated from aqueous nanoparticle inks provide an attractive alternative to conventional organic solvent based bulk heterojunction devices.

We present a dynamic Monte Carlo (DMC) study of s-shaped current-voltage (I-V) behaviour in organic solar cells. This anomalous behaviour causes a substantial decrease in fill factor and thus power conversion efficiency. We show that this s-shaped behaviour is induced by charge traps that are located at the electrode interface rather than in the bulk of the active layer, and that the anomaly becomes more pronounced with increasing trap depth or density. Furthermore, the s-shape anomaly is correlated with interface recombination, but not bulk recombination, thus highlighting the importance of controlling the electrode interface. While thermal annealing is known to remove the s-shape anomaly, the reason has been not clear, since these treatments induce multiple simultaneous changes to the organic solar cell structure. The DMC modelling indicates that it is the removal of aluminium clusters at the electrode, which act as charge traps, that removes the anomalous I-V behaviour. Finally, this work shows that the s-shape becomes less pronounced with increasing electron-hole recombination rate; suggesting that efficient organic photovoltaic material systems are more susceptible to these electrode interface effects.

CE can efficiently separate poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonic acid) (PEDOT/PSS) complexes and free PSS in dispersions and can be used to estimate the degree of PSS doping. We investigated the doping efficiency of PSS on PEDOT in dispersions using CE and its effect on the conductivity of the resulting PEDOT/PSS films. Results of this study indicate that dispersions containing 1:2.5-3 EDOT:PSS feed ratio (by weight) exhibiting 72-73% PSS doping generate highly processable and highly conductive films. Conductivity can be optimized by limiting the time of reaction to 12 h. At this point of the reaction, the PEDOT/PSS segments, appearing as broad band in the electropherogram, could still exist in an extended coil conformation favoring charge transport resulting in high conductivity. Above a threshold PEDOT length formed at reaction times longer than 12 h, the PEDOT/PSS complex, appearing as spikes in the electropherogram, most likely have undergone a conformational change to coiled core-shell structure restricting charge transport resulting in low conductivity. The optimal conductivity (5.2 S/cm) of films from dispersions synthesized for 12 h is significantly higher than those from its commercial equivalent Clevios P and other reported values obtained under similar conditions without the addition of codopants. © 2014 WILEY-VCH Verlag GmbH & Co.

Poly (3-hexylthiophene) (P3HT), at six molecular weights varying from 5 kDa to 72 kDa (Mw), was used to prepare P3HT: phenyl C61 butyric acid methyl ester (PCBM) nanoparticulate organic photovoltaic (NP OPV) devices and the effect of this variation on device performance is reported. Power conversion efficiency (PCE) is observed to peak for the mid-range of molecular weights tested, this behaviour varies from the trend generally observed with bulk heterojunction (BHJ) devices, where high molecular weight polymers deliver the highest PCEs. Here we demonstrate that polymer molecular weight affects the electronic, morphological and compositional structure of the nanoparticulate film. Significantly, it is the domain composition that is most highly correlated with device performance and this composition is driven by the PCBM mobility and aggregation within the nanoparticulate structure. © 2014 Elsevier B.V.

Conductive transparent carbon thin film electrodes have been grown on a copper foil using poly(methyl methacrylates) as a carbon source at a temperature below 450 °C, in contrast to the preparation temperature above 800 °C in the previously reported chemical vapour deposition method. Raman and UV-Vis absorption spectroscopy have been used to identify their graphene based composition. Scanning electron microscopy and Transmission electron microscopy have been used to characterize the film quality. Conductivity and transmittance of the thin films have been evaluated. Using the conductive transparent electrodes, organic solar cells have been successfully fabricated. This work paves a potential pathway for an easier and cheaper production of organic solar cells. © 2013 IEEE.

The impact of device dimension and architecture on the device performance of an all-solution fabrication organic thin film transistor (OTFT) has been investigated. The saturation drain current is inversely proportional to the channel length, indicating that a characteristic of field - effect like transistor has been obtained. In contrast, the drain current is independent of the thickness of polyvinylphenol (PVP) dielectric layer and a large leakage current is observed at the gate electrode indicating that the device also shows electrochemical transistor characteristics. Although separate conductance measurements of a single poly(3-hexylthiophene) (P3HT) layer and a P3HT/PVP layer reveal that the conductance is proportional to the thickness of the layer, the maximum achieved drain current in the fabricated OTFT is inversely proportional to the P3HT thickness. Using this data, an interface of P3HT/PVP or a maximum P3HT thickness for a working transistor of approximately 160 ± 16 nm can be extracted. The mechanism of operation of these devices is discussed. © 2009 Materials Research Society.
