Fa-Jun MA speaks at UNSW SPREE


Nowadays, TCAD becomes an indispensable tool in solar cell research, attracting researchers worldwide to increase TCAD involvement in their research. This talk aims to attract attentions of SPREE researchers and students and to arouse their interests to use TCAD in their research activities. It will point out that TCAD is mature enough to model complex semiconductor processes with a reasonable accuracy. The talk will enumerate a few benefits of TCAD-assisted research and will present previous work, where it was applied to performance improvement of silicon wafer solar cells. It will demonstrate to model in-depth recombination dynamics inside a solar cell during operation and will highlight possible efficiency gain due to reduce recombination losses.

Brief Bio

Fajun Ma just joined SPREE as a postdoc Research Fellow. He received his BEng degree in Material Science and Engineering from the Northeastern University, China in 2000; and his MSc and PhD degrees in Electrical Engineering from the National University of Singapore (NUS) in 2008 and 2014, respectively.

After graduation in 2000, he initially worked for five years on characterizing and optimizing microchip fabrication processes in two major microchip manufacturers. In the following three years, he worked on developing future microelectronics device technologies at NUS. Half of his time was spent on using a commercial TCAD software package, Sentaurus, to facilitate his research. In 2009, he joined the Solar Energy Research Institute of Singapore (SERIS) and worked as a dedicated TCAD researcher. He carried out various process, device and optical simulations with a focus on reducing carrier recombination losses in silicon wafer solar cells.
