Dr Ary Anggara Wibowo

Postdoctoral Fellow, School of Engineering, Australian National University (ANU)

Dr Ary Anggara Wibowo is a materials scientist and engineer at the Australian National University (ANU), specialising in the development of advanced semiconductors for next-generation photovoltaic and renewable-energy applications. His research focuses on the synthesis, defect engineering, and optoelectronic characterisation of wide-bandgap transition-metal dichalcogenides (TMDs) and chalcogenide compounds for high-efficiency silicon-based tandem solar cells. In parallel, he is actively engaged in research on photocatalysis, CO₂ reduction, hydrogen generation, and biofuel production, contributing to broader renewable-energy innovations.

Dr Wibowo employs industrially compatible thin-film deposition techniques—including chemical vapour deposition (CVD), physical vapour deposition (PVD), and atomic layer deposition (ALD)—to fabricate high-quality semiconductor layers. He utilises advanced optical and structural characterisation tools such as micro- and time-resolved photoluminescence (PL, TRPL), hyperspectral imaging, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) to uncover the relationship between structural order, excitonic behaviour, and carrier dynamics in layered materials.

He has authored and co-authored over thirty peer-reviewed publications in leading journals including Advanced Materials, ACS Nano, Nano Energy, ACS Catalysis, and Applied Catalysis B: Environmental. His work advances the understanding of defect passivation, bandgap modulation, and interfacial charge dynamics in low-dimensional semiconductors and catalytic systems, driving progress toward efficient and sustainable energy technologies.

Dr Wibowo’s research bridges fundamental materials science with applied renewable-energy engineering, aiming to pioneer new materials and architectures that enable high-performance solar cells, photocatalytic systems, and solar-fuel technologies.
