Dr Bradley Kirk is a researcher at Adelaide University specialising in advanced materials for photovoltaic and radiation-based energy conversion technologies. He completed his PhD in Chemistry at Flinders University in 2023, where his research focused on the development of scalable fabrication methods for organic photovoltaics (OPVs), investigating degradation mechanisms and improving device stability for the manufacture of flexible solar cells.
Since joining Adelaide University in 2024, Dr Kirk has contributed to the development and characterisation of betavoltaic devices in collaboration with entX Ltd., investigating how material composition, microstructure and processing influence device performance, radiation tolerance and operational lifetime. His research has since expanded into radiophotovoltaic technologies through the ARC Industrial Transformation Training Centre for Radiation Innovation (RadInnovate), with support from entX. This work explores the use of radioluminescent materials, including scintillators, to convert radiation into light that can be harnessed by photovoltaic devices for electrical power generation.
Dr Kirk's broader research interests include advanced energy materials, radiation-induced degradation, thin-film fabrication and characterisation, and the development of durable, efficient energy conversion devices. His work brings together materials science, device engineering and industry collaboration to advance radiation-based power technologies for applications requiring reliable, long-lived energy sources.
My research focuses on the development, processing and characterisation of advanced materials for photovoltaic and radiation-based energy conversion technologies, including betavoltaic and radiophotovoltaic devices. I investigate how material composition, microstructure, fabrication methods and radiation exposure influence device performance, stability and operational lifetime.
My current research encompasses two complementary approaches to radiation-based power generation. Betavoltaic devices directly convert the energy of beta particles into electrical energy, while radiophotovoltaic devices use radioluminescent materials, such as scintillators, to convert ionising radiation into light that can subsequently be converted into electricity by a photovoltaic cell. Through my work with the ARC Industrial Transformation Training Centre for Radiation Innovation (RadInnovate) and industry partner entX Ltd., I contribute to the development and evaluation of materials and device architectures for reliable, long-lived power generation, with potential applications in space, defence and remote or resource-constrained environments.
I have experience in a range of materials characterisation techniques, including scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), photoluminescence spectroscopy and imaging, and radiation-related characterisation methods. My expertise also includes thin-film deposition and coating using vacuum-based techniques, including thermal evaporation and sputtering, and solution-based methods, including spin coating, blade coating and slot-die coating, across flexible and rigid substrates.
Building on my doctoral research in organic photovoltaics, I am particularly interested in understanding the relationships between material properties, processing conditions, degradation mechanisms and device performance. By combining materials characterisation, fabrication expertise and collaborative research with industry, my work aims to support the development of scalable, robust and efficient energy conversion technologies.
