Dr Sisi Wang is a research associate in the school of photovoltaics and renewable energy engineering. She completed her PhD at UNSW focused on the development of laser doping process that simultaneously grooves the silicon followed by self-aligned plating metallisation, as well as laser-based implementations for the advanced hydrogenation technology. Dr Wang is an ACAP research fellow and a CI on ARENA research project. Her research interests are on cost effective solar cell metallisation and material sustainability for TW scale production of PV.
