Dr Fa-Jun Ma is the modelling and simulation officer in the School of Photovoltaic and Renewable Energy Engineering at the UNSW Sydney since 2015. Before joining UNSW, he was the head of modelling and simulation team in Solar Energy Research Institute of Singapore. He received his PhD in Electrical & Computer Engineering from the National University of Singapore in 2014.

Since 2009, he has been leading process, optical and electrical simulations with advanced models and numerical methods for high-performance and emerging solar cells. His research interests cover high-efficiency silicon solar cells, CZTS/Se, perovskite, III-V and silicon-based multijunction solar cells. Depending on the nature of problems, he chooses or combines optimal simulation tools like Sentaurus, SCAPS-1D, AFORS-HET, Quokka, GEANT4, SRIM, Griddler, etc. To overcome the limitations of these tools, he codes with program languages like TCL, C++, Scheme, Python, VBA, etc. to either extend their capabilities or develop his own calculators. Prof. Bram Hoex was his PhD thesis adviser, and he is currently working on space silicon solar cells in the Hoex group.
