Dr Yu-Han Chang is a Senior Technology Analyst at IDTechEx working predominantly on advanced materials.
Dr Chang previously worked as an Etching Process Engineer in Taiwan Semiconductor Manufacturing Company (TSMC) from 2012-2014, where she gained experience of working with 16 nm to 40 nm technology.
Yu-Han has a PhD in Chemistry from Imperial College London. Her research was focused on charge carrier dynamics of Cu(In,Ga)Se2 (CIGS) thin-film solar cells utilising transient absorption spectroscopies. Her PhD work resulted in two first-author publications in the top 2% journals in the field of materials science: Advanced Energy Materials and Advanced Functional Materials.
She obtained her master's and bachelor's degree in Materials Science and Engineering at the National Tsing-Hua University in Taiwan. Her master research focused on synthesising Indium sulphide non-toxic layer for CIGS thin-film solar cells.
Yu-Han has a total of 8 years of experience working with semiconductor and photovoltaic materials. She has also acted as an associate consultant for a London renewables start-up and evaluated the investment potential of expanding their business to SE Asia.
Yu-Han enjoys organising STEM outreach activities, promoting science and renewable energies to the general public. She held 4 outreach events at Imperial College London and Science Museum London during her PhD and acted as an ambassador for many more.
