Career Summary
Biography
The future belongs to those who create it! Dr Matthew Griffith is working to build a future with electronic devices can sense the world and then interface with and control functionality in the human body. To achieve this vision he is developing a series of sensing and stimulation platform technologies by printing clever electroactive inks into functional and flexible devices.
Research Overview
Life is short, so build things that matter. A continuing theme of Dr Griffith's research since he received a PhD in physical chemistry from the University of Wollongong has been the links between molecular structure and electronic functionality in organic and inorganic semiconducting devices. His research spans a broad area of applications, from the fundamental science of optical processes and charge carrier behavior in semiconductors to the fabrication of printed sensors and bioelectronic devices on the roll to roll scale scale for industry.
Energy Generation
The Sun produces more energy in an hour than the entire global population will use in a year. The future will require renewable energy generation technologies, and Dr Griffith has a plan to create these devices using specialized polymer materials. In 2010 he secured a Prime Minister's Asia Australia Award to conduct work across three different countries focused on understanding how control of molecular structure can manipulate charge carrier transport and recombination processes in the next generation of advanced solar cells. This work allowed him to develop a deep understanding of how fundamental processes occurring at the nanoscale can direct the important device performance metrics observed on the macroscopic scale. This allowed intelligent design processes to replace educated guessing in the design of advanced solar cells. This process was achieved by creating molecular design principles and strategies to control charge carrier kinetics for maximizing solar energy power conversion. In a post-doctoral fellowship in Japan he extended these studies to examine ionic movement in organic electronic mixed conduction devices and demonstrated how this could be controlled to create efficient 3‐D light sensors. The molecular design principles and charge carrier manipulation strategies developed by Dr Griffith have been heavily employed through the dye-sensitized community and have led to porphyrin dyes being widely adopted by other world-leading researchers and currently holding the record for the solar conversion efficiency in these devices. This has in turn provided significant tangible benefits to companies attempting to commercialise these devices, including DyeSol and G24i Power.
Printable Sensors
To control the world you live in, first you must detect and understand the signals by which that world communicates. In 2013 Dr Griffith moved to the University of Newcastle to establish a new research program in printed electronics. He has developed new innovative manufacturing techniques focused on solution‐based coating of organic electronic components for energy generation, light sensing and initiation of explosives in revolutionary large area printing facilities that have produced industrially relevant prototype devices. The ability to transfer fundamental physical stimuli such as pressure, light and chemical reaction products into electrical signals using a low cost printed organic semiconductors has proven to be a major technological breakthrough, and has led to the deployment of Australia's first commercial organic photovoltaic and sensing devices.
Biomaterials Science and Bioelectronic Devices
Carbon-based problems require a carbon-based solution. In his most recent research, Dr Griffith has continued exploring his passion for multidisciplinary research by working to interface the world of biology with his background in materials chemistry and device physics. The work has involved interfacing printed electronics with biomedical applications, and in some exciting instances, talking directly to living cells. The human body uses sensory neurons to communicate with the brain, which operate in a very similar manner to electronic devices with the added complication that they operate through the exchange of both ions and electrons. In comparison, standard silicon semiconductor technology operates purely through the exchange of electrons alone. However, the carbon-based organic electronic materials that Dr Griffith has been developing over the past decade offer a revolutionary platform that are uniquely capable of both ion and charge transport. Furthermore, these soft and pliable organic semiconductors are seamlessly biocompatible with the soft carbon-based tissue of the human body. These materials therefore offer exciting potential as the first electronic devices that can interface directly to the human body.
Dr Griffith is passionate in his belief that these organic semiconducting materials hold the key to unlocking next-generation biomedical devices that has always been at the forefront of the human imagination. He is currently developing fully printable devices that can detect ionizing radiation for interfacing to medical X-ray and nuclear medicine procedures, light activated neurostimulation devices for artificial retina implants, and electrically stimulated devices for implantable smart drug delivery systems. He was awarded an Early Career Researcher Strategic Pathway Grant and a Early Career Researcher Equipment Grant to develop the device physics of these new biomaterials device and currently leads the medical physics and bioelectronics research efforts in the Priority Research Centre for Organic Electronics.

This work investigated the photophysical pathways for light absorption, charge generation, and charge separation in donor-acceptor nanoparticle blends of poly(3-hexylthiophene) and indene-C60-bisadduct. Optical modeling combined with steady-state and time-resolved optoelectronic characterization revealed that the nanoparticle blends experience a photocurrent limited to 60% of a bulk solution mixture. This discrepancy resulted from imperfect free charge generation inside the nanoparticles. High-resolution transmission electron microscopy and chemically resolved X-ray mapping showed that enhanced miscibility of materials did improve the donor-acceptor blending at the center of the nanoparticles; however, a residual shell of almost pure donor still restricted energy generation from these nanoparticles.

All rights reserved. We demonstrate a pathway for fully roll-to-roll (R2R) prepared organic solar cells in a normal geometry with a R2R sputtered aluminium top electrode. Initial attempts utilizing a stack geometry without an electron transport layer (ETL) failed to obtain working devices. By applying aluminium zinc oxide (AZO) as an ETL, and optimizing the AZO thickness, working printed OPV devices with an efficiency of 0.58% were obtained. Further optimization of the donor:acceptor ratio in the active layer increased the efficiency to 0.90%. This work demonstrates that normal geometry organic solar cells using a metal top contact can be produced using large scale production techniques.

The potential for organic electronic technologies to produce low-cost energy at large scales is often cited as the most attractive feature of these materials. Such aspirations depend on the ability of materials to be printed from solution at high speeds across large areas using roll-to-roll (R2R) processing. However, progressing the technology from the laboratory environment into the industrial manufacturing arena is highly challenging. Closing the gap between exciting laboratory scale insights and the industrial scale potential requires a new focus on upscaling existing technology. Some recent progress in this area is discussed, concentrating on the need to pursue research across several different scales simultaneously in order to most effectively optimize large-scale fabrication efforts. These discussions are placed in the context of a design philosophy that combines printing, coating, and vacuum-based procedures. The challenges associated with selecting, and subsequently synthesizing, the optimal materials for device construction at large scales are considered. Case histories that highlight the unique challenges encountered during printing, coating, and sputtering at the R2R scale are presented. Developing testing and characterization procedures that can interrogate organic photovoltaic device (OPV) structures in real time is also discussed, and the opportunity for new tools to probe device photophysics is highlighted. The collection of innovative approaches to R2R fabrication challenges discussed here highlights the exciting progress toward efficient OPV modules becoming a commercial reality.

We investigate the suitability of four different inorganic materials (chromium oxide (CrOX), titanium oxide (TiOX), aluminium doped zinc oxide (AZO) and zinc oxide (ZnO)) as electrode transport layers in fully roll-to-roll (R2R) fabricated P3HT:ICxA organic solar cells. CrOX and TiOX were found to be unsuitable, as the CrOX devices did not exhibit rectifying behaviour while the TiOX devices did not withstand the annealing conditions. Of the last two ETLs, ZnO showed by far the most promise with devices demonstrating an average efficiency of 2.2%, which is the highest reported value for R2R devices in normal geometry, and a significantly extended lifetime compared with AZO devices under ISOS-L-2 conditions.

A series of Zn(II) porphyrins which have asymmetrically substituted meso groups have been studied with UV-vis, resonance Raman, emission spectroscopies, and density functional theory (DFT) calculations. Dye-sensitized solar cells (DSSCs) of these materials have also been fabricated and their performance parameters measured. DFT calculations show perturbation of frontier molecular orbitals, and redox-active substituents cause greater perturbation than nonredox active substituents. All substituents cause a broadening of the B band, as is common for substituted porphyrins. TD-DFT calculations and resonance Raman spectroscopy suggest the donor and acceptor substituents play a small role in transitions of the B band. The meso donor substituent is electronically isolated and does not significantly perturb the molecular orbitals (MOs), while the meso cyanoacrylic acid TiO<inf>2</inf> binding group has a much larger effect on the e<inf>g</inf> MO in particular. However, in the oxidized porphyrin species, the hole is located on the meso substituent, localizing it away from the semiconductor surface, which should reduce recombination and also improve performance. They show modest efficiency when incorporated into solar cells; however, the pattern of behavior is consistent with localization of charge at the meso unit.

The purpose of this work is to investigate the origin of improved photovoltaic performance of a series of di-chromophoric carbazole-substituted porphyrin dyes employed as sensitizers in dye-sensitized solar cells. Five di-chromophoric zinc porphyrin dyes with the same porphyrin core, a carbazole unit attached in the meso-position through a phenylethenyl linkage, and substituents spanning a range of electron affinities, in an attempt to tune the electronic level of the carbazole unit, have been synthesized (CZPs). Density functional theory (DFT) calculations predicted the nature of the electronic transitions observed in the CZP systems, showing a large degree of orbital mixing. In contrast, UV-vis absorption, resonance Raman spectroscopy and differential pulse voltammetry investigations suggested negligible interaction between the porphyrin and carbazole chromophores. Carbazole substitution led to a moderate increase in photon absorption intensity within the ~300 nm to 400 nm wavelength region, a smaller but broader Soret band absorption and slightly increased photon absorption intensity in the 550 nm to 650 nm Q band region. Despite the rather small changes in light harvesting and negligible changes in the HOMO/LUMO electronic levels, the photovoltaic performance of the new dyes is increased by as much as 30% compared to the single chromophore Zn porphyrin dye 5-(4-(2-cyano-2-carboxyethenyl)phenyl-15-phenyl-10,20-bis(2,4,6-trimethylphenyl)porphyrinato zinc(ii) (ZP1), leading to over 6% power conversion efficiencies (PCEs). Both open circuit voltage (VOC) and short circuit current (JSC) have increased. The increased VOC is attributed to increased electron lifetimes due to a steric blocking effect. Analysis of the increased short circuit current (¿JSC) showed that only less than 10% of ¿JSC originates from increased light absorption under simulated air mass 1.5 illumination, while the rest of the improvements are attributed to a steric effect enhancing the electron injection efficiency. These results suggest that developing non-conjugated multichromophoric dyes can lead to simultaneous increases in both the photocurrent and the photovoltage of dye-sensitized solar cells.

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.

Nanoengineered Bioelectronic Systems for All-Optical Control of Neuron Growth and Stimulation$757,452
Nerve cells are the primary signal carriers of the human body. When they cease to function normally, our ability to sense the physical world is influenced catastrophically. The project will develop new insights into the ability to control the growth and stimulation of neuronal cells using printable organic conducting scaffolds. At the completion of the project, we will establish the impact of 3D electroactive material structure on promoting neuron growth and activating neuron signals using all-optical stimulation of the organic conductors. These insights will be a revolutionary step forward in creating biocompatible and flexible medical devices that interface with neurons, with applications ranging from repair of neuronal tissue to treatment of neurological disorders and creation of artificial sensing organs.
