报告时间：2017年4月25 日 上午 10:00-11:00
摘要：For solar cells to work efficiently, it is essential to suppress the recombination between electrons and holes, both in the bulk and at the surfaces, and to create regions in the device that transport the two charge carriers towards two separate metallic electrodes. This talk will describe several approaches to implement such passivating technologies on silicon. Firstly, I will present the progress in developing novel surface passivating materials at ANU. Secondly, I will discuss self-passivating contacts formed by doped polysilicon films deposited onto thin, tunnelling dielectrics, and also dopant-free selective contacts based on materials having either a very low or very high work function. The latter include metal, metal fluorides and metal oxides. Recent research on deposited-junction silicon solar cells made with such materials will be overviewed.
个人简介：Dr. Yimao Wan received the B.E. degree from the Nanyang Technological University, Singapore in 2004, and Ph.D. degree from the Australian National University (ANU) in 2014. He has six years industrial experience in semiconductor manufacturing between 2004 and 2010. He is currently a research fellow at the ANU co-leading with Prof Andres Cuevas the Silicon Passivation group and managing the ANU-ARENA industrial projects. During 2016 to 2017, he has been a visiting fellow at University of California, Berkeley under supervision of Prof Ali Javey. Since commencement of PhD, Dr Wan has published 34 journals and 17 conference articles on silicon surface passivation and carrier-selective, passivated contacts. His research interests lie particularly on the following aspects:novel surface passivation and carrier-selective contact materials；high-efficiency low-cost silicon solar cells and silicon/perovskite tandem solar cells；novel materials and devices for photoelectrochemical applications.
