Dr. Weijian (Will) Chen -  ACAP fellow at Australian Centre for Advanced Photovoltaics (ACAP), School of Photovoltaics and Renewable Energy Engineering (SPREE), UNSW Sydney.

His research interests focus on spectroscopic technique, numerical methodologies and data analytic techniques for multi-dimensional microscopical imaging characterisation of emerging materials for energy-harvesting and light-emitting applications.

He was awarded Doctor of Philosophy in SPREE of UNSW Sydney, Australia in 2018.

During his PhD candidature, he also worked as a visiting scientist at Max Planck Institute for the Science of Light in 2016, funded by German Academic Exchange Service (DAAD).

After his Ph.D. graduation, he worked as a post-doc research fellow in Centre for Micro-Photonics and Centre for Translational Atomaterials in Swinburne University of Technology between 2018 and 2020.

During this post-doc appointment at Swinburne, he visited KAUST Solar Center (KSC) for a 3-month cooperation at King Abdullah University of Science and Technology, Saudi Arabia.

Weijian's current project is on the development of optical characterization techniques and recombination analysis routines for understanding carrier dynamics of emerging photovoltaic materials and devices.

These works directly contribute to the research of organic and earth-abundant inorganic thin-film solar cells and optics/characterization by developing advanced spectroscopy characterization methods aiming at analyzing perovskite and other similar kinds of solar cells.

With routinized characterization method aided by numerical carrier dynamical modeling, the techniques developed advance the state-of-the-art solar technologies and prepare for future-emerging novel materials and advanced concepts in photovoltaics, and ultimately deal with the human challenge of dependence on fossil energy sources, energy crisis, and global warming issues.

Research Interests:

  • Photo-physics Characterization & Application of Optoelectronic Materials, particularly mobile ions and charge carriers in perovskites;
  • Ultrafast spectroscopy and time-resolved micro-spectroscopy;
  • Photophysics of (semiconductors, metallic and graphene-based) nanomaterial.
