Dr Wenxin Mao | ARC Centre of Excellence in Exciton Science

Dr Wenxin Mao

Research Fellow

Dr. Wenxin Mao completed his PhD from Monash University under the supervision of Prof. Udo Bach, and co-supervised by Prof. Paul Mulvaney at the University of Melbourne. He is now an ACAP Postdoctoral Research Fellow. His research interests include the study of growing mechanism for crystalline halide perovskite materials with different structures and their optoelectronic properties. He is keen to put these exciting materials in the applications in next generation solar cells, LEDs and radiation imagings.
