I am devoted to capturing the scientific secrets of light. With my investigations, I pursue the deepest understanding of such natural phenomena to develop leading edge technology for clean energy harvesting. We have to move towards clean sources to prevent devastating effect for the next generation.

Education Profile

  • Ph.D., National Tsing Hua University, Taiw​​an, 2005
  • B.S.,​ National Tsing Hua University, Taiwan, 1999​​​

Jr-Hau He is an Associate Professor of Electrical Engineering (EE) and Principal Investigator of the Nano Energy Lab Nano Energy Lab.  His expertise is in the development of transparent and flexible electronics using novel devices based on nanomaterials, including solar cells and photodetectors, LEDs, and memory devices.

Education and early career

He was a Visiting Scholar at Georgia Tech (2005), a Postdoc Fellow at National Tsing Hua University (2006) and Georgia Tech (2007), a Visiting Professor at Georgia Tech (2008), UC Berkeley (2010 and 2014), and UC San Diego (2012-2013), HKPolyU (Dec. of 2014), and University Lille 1 (May of 2016) and a tenured Assistant/Associate Professor at National Taiwan University (2007-2014).

Areas of expertise and current scientific interests

He has been a pioneer in optoelectronics, which reflects on his achievement of photon management on the light harvesting devices. He has conducted highly interdisciplinary researches to bridge those gaps between various research fields and between academia and industry. The great success of his research is reflected by his research funding, publications, awards, honors, patent and technology transfer to industry. He has grants received: > US$ 11M and garnered ~10000 citations for a body of work consisted of >200 peer-reviewed journal articles and 18 patients with 53 of H factor over his career and over 200 presentations in international conferences. The nanotechnology he has developed has been transferred constantly to energy and LED industry in Taiwan and Saudi Arabia.

Editorial activities

He serves as a member of the editorial board for numerous prestigious journals, and as a chair, co-chair, and a member of technical and steering committees for national and international symposiums. He is the Vice President of Saudi Arabia Section of OSA (2015-current), OSA Nanophotonics Technical Group Member, and OSA Travelling Lecturer. He was the Faculty Advisor of the OSA Student Chapter of National Taiwan University (2014). 

Why nanomaterials?

Harvesting and producing clean energy urges new, efficient and cost-effective technologies. His particular interest in solar energy encompasses light scattering and trapping in nanostructured materials to design next-generation solar cells. He also investigates the transport of charge carriers across these solar cells and improving light coupling to increase the efficiency of photoinduced charge separation. 


KAUST is the natural hub for my projects. No other place can offer top-nock facilities along with full support for research like KAUST.  Last but not least, I found top-class international colleagues and students with a shared vision for a better, clean and sustainable future.
