Organic and organic-inorganic hybrid perovskite semiconductor materials continuously attract much attention in recent years due to their great applications in solar cells, photodetectors, light-emitting diodes, etc., resulting from their prominent light harvesting, solution-process ability, controllable energy levels and low cost. Especially, there has been an unexpected breakthrough and rapid evolution of highly efficient perovskite solar cells (PSCs) and organic solar cells (OSCs), of which the PCEs have been over 23 % and 14 %, respectively [1-3]. Photodetectors, converting the incident light to electrical signals, show great applications in biomedical sensing, imaging, optical communications, and environmental monitoring. The morphology control and interface engineering are powerful approaches to improve the performance of solar cells and photodetectors. In this presentation, we will introduce our research progress on printing fabrication on organic/perovskite solar cells and photodetectors via roll-to-roll printing process and doctor blading under ambient conditions [4-9]. The experiment results suggest that printing parameters and ink formulations play very important roles on the interface and morphology properties of printed films, which dramatically influence the device performance parameters. The research results would accelerate the development of organic/perovskite materials and devices from the lab to the commercialization.

Prof. Junliang Yang received his PhD degree in 2008 from State Key Laboratory of Polymer Physics and Chemistry at Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. Then he worked as a postdoctoral research fellow in the Department of Chemistry at the University of Warwick (UK) for two and half years. In April 2011, he moved to Australia and worked as a research fellow in Bio21 Institute at the University of Melbourne and as a visiting scientist in Flexible Electronics Laboratory at the CSIRO. In March 2012, he was appointed as a full professor in the School of Physics and Electronics at Central South University. His research interests focus on flexible and printed electronics, as well as organic/perovskite solar cells. He has published over 120 papers and granted over 10 patents. He is the member of the technical committee (Beijing Branch) of The Society for Information Display, the member of the expert group on Printing Electronics Standardization of International Electrotechnical Commission(IEC/TC119) and the member of editorial board of the journal Scientific Report.
Central South University (CSU) is situated in Changsha, a famous historical and cultural city in Hunan, China. As a top university directly under the Ministry of Education (MOE) of the People’s Republic of China, CSU is one of the first universities admitted into “Project 211”, “Project 985”, and “Plan 2011”. In September 2017, CSU was enlisted as one of the A-Level “Double First Rate” universities by the State Council. The university drives collaborative innovation and serves the development of the national economy and the modernization of national defense. It has 20 national-level innovation platforms, including 2 national key laboratories, 4 national engineering research centers, 5 national engineering laboratories, and so on.
