Dr Ran Chen

Lecturer

Awarded PhD from the School of Photovoltaics and Renewable Energy Engineering (SPREE), UNSW, Sydney, Australia in 2017. Thesis topic is titled "Low-temperature hydrogenation for plated silicon solar cells".

Engineering
Photovoltaic and Renewable Energy Engineering

Ran Chen submitted her PhD in March 2017 which focused on technology development for advanced hydrogenation in p-type multi wafers and solving light-induced degradation in such silicon. She has published numerous related papers and been an inventor on 7 patents for innovative approaches for controlling the charge state of hydrogen atoms in silicon. Her patent for using sub-bandgap photons to convert H- into H0 is of particular importance for the new n-type advanced hydrogenation technology being developed in her PhD has been awarded Category 1 research funding from the Australian Research Energy Agency (ARENA) and also She is an expert on solving contact resistance problems originating during hydrogenation due to passivation of metal/silicon interfaces and the adhesion of the metal contacts.
