Sahil Shah

  • Post Doctoral Research Fellow
  • The University of Queensland


Sahil Shah is a postdoctoral researcher at The University of Queensland (UQ), where he explores the device physics of organic and hybrid optoelectronic devices. His work focuses on understanding charge carrier and ionic dynamics in next-generation semiconductors, with a particular emphasis on developing transient electrical measurement techniques to probe these effects in real time along with device simulations.

Before joining UQ, Sahil completed his PhD at the University of Potsdam, Germany, where he investigated the role of ion migration in perovskite solar cells and tandem architectures. His research introduced fast hysteresis methods and subcell-selective measurements to quantify ionic losses, offering new insights into performance degradation and recombination processes in working devices. He contributed to several high-profile publications in Nature Energy, Advanced Energy Materials, and Nature Communications.

Sahil’s background is in experimental physics, combining device fabrication and characterization with electrical modelling and simulation. He has hands-on experience with techniques like Photoluminescence (PL) and electroluminescence (EL) spectroscopy, Suns-VOC, bias-assisted charge extraction (BACE), CELIV, and transient photocurrent, photovoltage and JV analysis. At UQ, he aims to continue this line of work by developing high-performance photodetectors and photovoltaics, integrating novel semiconductors, and applying advanced time-resolved techniques to uncover fundamental transport phenomena together with drift-diffusion device simulations.

Alongside his research, Sahil is passionate about science education and innovation. He co-founded a startup focused on developing a novel tool for solar cell diagnostics and has been involved in research-based teaching initiatives supported by the German Research Foundation through SPP2196. His experience spans academic and entrepreneurial roles across Germany, India, and now Australia.
