Topic: Scalable manufacture of organic solar cells
Time: 10:30 AM, Oct. 9th (Sunday)
Location: Conference Room B, BLDG 909-1F
Renewable clean energy is one of the most profound challenges faced by human society. Organic solar cells have been under rapid developments for past decades, owning to their low cost and short energy-pay-back-time due their solution processability. Until now, most of the high performance solar cells manufactured in lab uses spinning coating method. However, spin coating method is not scalable. And the power convert efficiency of those cell drops significantly once scaled up using roll-to-roll printing. The gap between lab scale and industrial scale manufacture yet to be filled. In this talk, I will present recent works in Prof. Zhenan Bao group aiming to close this gap. We used advanced real time X-ray diffraction techniques to understand the morphology development during the roll-to-roll printing process. Based on this morphology understanding, we further optimized an all polymer solar cell that can be scaled up from a lab scale spin coating to consciously roll-to-roll printing method using a custom built roll-to-roll coater without significant efficiency loss.
Dr. Xiaodan Gu currently is a post-doc researcher in Chemical Engineering department at Stanford University working with Prof. Zhenan Bao. Starting Nov, 2016, he will join the faculty of the Department of Polymer Science and Engineering in Univ. of Southern Mississippi. His research interests include soft materials, energy science, biomaterials and surface/interface sciences. He received his B.S. degree (Honors) in chemistry from Nanjing University in 2008, and Ph.D. degree in Polymer Science and Engineering from University of Massachusetts at Amherst (USA) in 2014 with Prof. Thomas P. Russell. He also worked as student researcher at the Advanced Light Source using state-of-art X-ray synchrotron source to study diblock copolymer self-assembly from 2011 to 2014. So far, He has published about 25 scientific articles, including in Nature Communications, Adv Mater, JACS and PNAS. He has awarded with several honors including Advanced Light Source doctoral fellowship.
