| 报告介绍 | 报告摘要：
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 recent developments in printing of DSSCs and OPVs in Australia will be presented. But the focus will be on the recently developed perovskite solar cells. PSCs have achieved extraordinary efficiency improvement in just a few years. They can be produced by solution based coating techniques, but the normal one-step coating process produced films consisting of non-uniform dendritic perovskite grains, resulting in poor power conversion efficiency. We have recently developed some novel processing techniques that can achieve uniform perovskite films and consistently high power conversion efficiency. The importance of controlling the nucleation and crystal growth during the spinning coating and the effect of the microstructure of perovskite films on the device performance will be discussed.
