ChE graduate student Ryan Ellis wins first place at 2019 AIChE Annual Meeting
Davidson School of Chemical Engineering graduate student Ryan Ellis received a first-place award at the 2019 AIChE Annual Meeting for his presentation in the Electronic and Photonic Materials Graduate Student Awards Session sponsored by JVST. Ellis was one of six students presenting in this category.
In his oral presentation, Synthesis and Ligand Engineering of Impurity Free Cu(In,Ga)S2 Nanoparticles for Slot-Die Coated Photovoltaics, Ellis discussed existing limitations of nanoparticle based solution processed Cu(In,Ga)(S,Se)2 photovoltaics, and the methods he utilized to bypass these limitations through novel synthetic methods using elemental metals as precursors, ligand exchange pathways to remove carbon impurities, and slot-die coating to address scalability issues.
Ellis (pictured second from left) is advised by Dr. Rakesh Agrawal, the Winthrop E. Stone Distinguished Professor of Chemical Engineering, and works in Dr. Agrawal’s Solar Energy Research Group. His research is focused on solution processing of thin film photovoltaics in a low-cost, high-throughput method of manufacturing as compared to traditional high vacuum batch processes. Ellis will graduate in 2020 with his Ph.D. in Chemical Engineering.
