Abstract
Photovoltaics is essentially an interaction between sunlight and materials. The underlying physics of this interaction are relatively well understood for the cases where the feature sizes of the material in question are larger than the wavelength of the light striking it. However for very small features, at the nano-scale for example, there are plenty of phenomena that are neither fully understood nor manipulated. The speaker sees this area as an opportunity for further development of high-efficiency, affordable photovoltaic devices. This is a rather large topic, so the speaker will focus on a few nano-technologies that he has had research experiences with, i.e., nano-plasmonic/plasmonic light management and metallic nano-networks for transparent electrodes.

Brief Bio
Zi Ouyang received his bachelor of physic degree at Nanjing University of China with a thesis project on photocatalytic hydrogen energy generation in 2005. He obtained his PhD at SPREE of UNSW with a topic on polycrystalline silicon thin-film solar cells in 2011. Before he came back to UNSW as an ASI/ARENA fellow for a project to develop some advanced rear-contact schemes for crystalline silicon wafer solar cells, he worked in Swinburne University of Technology applying some advanced nanophotonic and nanoelectronic technologies to improve the performance of wafer solar cells. He has a little bit of experiences on 3 generations of photovoltaics, and his research interests always lie on any novel photovoltaic design concepts that have a chance to become a commercial product.
