摘要:

Solar cells that can be manufactured by solution based deposition techniques have potential to be low cost photovoltaic technologies. They can be made by continuous coating or printing techniques and possibly on flexible polymer substrates as well. Since the discovery of dye sensitised solar cells over twenty years ago, a number of efficient solar cell systems have been developed with solution based approaches. Some typical examples include dye sensitised solar cells (DSSC), organic solar cells (OPV) and more recently perovskite solar cells (PSC). In this talk some developments in printing of DSSCs and OPVs in Australia will be introduced. But the focus of the presentation will be on the recently developed perovskite solar cells. PSCs have achieved extraordinary efficiency improvement in just a few years. PSCs can be produced by solution based coating techniques, but the normal one-solution spinning coating produced films consisting of non-uniform large rod shape perovskite grains, resulting in poor power conversion efficiency. This presentation will introduce some novel processing techniques for making uniform perovskite films and discuss the importance in microstructural control of the perovskite films for achieving devices with high power conversion efficiency.

 

个人简历:

Yi-Bing Cheng(程一兵)is a professor in Department of Materials Engineering at Monash University and an elected Fellow of the Australian Academy of Technological Sciences and Engineering. He completed his undergraduate (1978) and Master (1983) studies at Wuhan University of Technology, China and received a PhD degree from University of Newcastle-upon-Tyne, U.K. in 1989. He joined Monash University in 1991 after three years of postdoctoral research in the U.K. and worked through as a Lecturer, Senior Lecturer, Reader and Professor at Monash University. He specialises in inorganic materials and composites and has worked in a number of research areas covering glass, glass-ceramics, structural ceramics, ultra high temperature ceramics and ceramic-polymer composites. He started working on dye sensitised solar cells in 2001 and has been focused on the processing of the solar cell devices by printing techniques, which has received significant grants from the Australian government and industry. His work has received a number of awards in Australia and overseas. He has published over 360 research papers and is an inventor of 17 patents. He is currently a Thousand Talent Professor at Huazhong University of Science and Technology, Wuhan National Laboratory for Optoelectronics.
