Welcome to my personal pages!

My name is Thien Truong, first from Binh Dinh, Vietnam (1993-2018), then from Canberra, Australia (2018-2024). Currently, I live in Lakewood, CO, USA (from 2024 onwards).

In Vietnamese, my name is "Trương Ngọc Thiện". I publish papers in the names: Thien Truong, Thien N. Truong, T. Truong, T.N. Truong, or Thien Ngoc Truong.

I am a materials science researcher specialized in solar photovoltaics (PV), currently at the US National Renewable Energy Laboratory (NREL), Materials, Chemical, and Computational Science Directorate (MCCS), High-Efficiency Crystalline PV Group.


Dr. Thien Truong received his PhD in Engineering from the Australian National University (ANU), Australia in 2022. Prior to that, he obtained an MSc in Intelligent Micro/Nano Systems from Konkuk University, South Korea in 2018, and a Degree of Engineer in Mechanical Engineering from Ho Chi Minh City University of Technology and Education, Vietnam in 2015.

His research focuses on the applications of advanced characterization techniques and the development of silicon solar cells. He specializes in novel passivating contact technology for silicon photovoltaics and is actively involved in research areas such as perovskites, tandems, III-V materials, 2D materials, and (photo)electrocatalysis.

Before joining NREL in Jan 2024, Thien served as a postdoctoral researcher at the ANU Solar PV Lab from 2021 to 2023. During this period, he contributed to various Australian National Renewable Energy Agency (ARENA, Australia), Jinko Solar (China), and Centre Suisse d' Electronique et de Microtechnique (Swiss Center for Electronics and Microtechnology, CSEM, Switzerland) funded projects, focusing on the development of advanced poly-Si passivating contacts for high-efficiency silicon solar cells. Currently at NREL, Thien is engaged in research on high efficiency Si solar cells and  advanced metallization for different solar cell technologies.
