Title: Printable Thin Film Organic/Perovskite Solar Cells: From Materials to Device Stability

Abstract:Printing has been considered as the most power technology for precision additive manufacturing of organic electronics. In Suzhou Institute of Nano-Tech and Nano-Bionics (SINANO), the printed photovoltaic research group has been working on printing process for organic/perovskite solar cells for several years. With the efforts we have made, we are now able to print transparent silver nanowires (AgNW) electrode with highly balanced conductivity and transparency,[1,2] highly conductive ZnO interfacial materials to smooth the interface charge transport and injection[3], as well as the photoactive layer with favorable nanophase separation[4], and a highest power conversion efficiency of over 17% was successfully achieved for 1 cm2 flexible PET substrate. By proper interfacial protection, degradation of OPVs can also be minimized, yielding a T80 over 5000 hours.[5] In this presentation, I will give a brief introduction on these recent achievements

Dr. Chang-Qi Ma received his PhD degree at the Technical Institute of Physics and Chemistry,Chinese Academy of Sciences in 2003. After that he was a postdoctoral research assistant at Heriot-Watt University in Edinburgh, UK, until he joined the research group of Professor Peter Bäuerle at the University of Ulm in 2004 as a Humboldt research fellow. From January 2007 till May 2011, he did his Habilitation in Institute of Organic Chemistry II and Advanced Materials, Ulm University.Since June 2011 he joined Suzhou Institute of Nano-Tech and Nano-Bionics,Chinese Academy of Sciences, as a professor of chemistry. His research group mainly works on printed organic/perovskite solar cells and precision printing processes for electronics. He has published over 180 papers and filed over 30patents.
