Dr. Hongwei Han is Professor at Huazhong University of Science and Technology (HUST) and Wuhan National Laboratory for Optoelectronics (WNLO), and is now Deputy Director of the Michael Grätzel Center for Mesoscopic Solar Cells. Dr. Han obtained his bachelor degree from the College of Chemistry and Molecular Science in 2000 and his doctor degree from the School of Physics and Technology in 2005 at Wuhan University. And then, Dr. Han continued his research work at Monash University of Australia as postdoctor. Dr. Han joined HUST and WNLO in 2008 and began to establish his group of solar cells. Since 2000, Dr. Han has worked on the study of mesoscopic solar cells, his more than 40 SCI-indexed peer-reviewed papers have been published in the international journals such as Adv Funct Mater., Energy Environ Sci. et al. Moreover, two chapters in two professional books and 13 inventive patents have been issued. As an instructor, he instructed an institute team and won the highest prize in the first undergraduate optoelectronic design competition of China in 2009. His work monolithic solid-state mesoscopic solar cells exhibits promising application prospects and was regarded as "opens up a path to rapid commercial development of prochoice dye-sensitized solar cells". Dr. Han devotes himself to the research and development of low-cost solar cells, aiming to make a contribution to the development of renewable energy.
