ABSTRACT
Emerging technologies such as lightweight perovskite solar cells and earth-abundant electrocatalysts for water splitting can become central drivers of the renewable energy transition, but the impact of these systems remains limited by their performance and stability. Here we pose that scalable nanomanufacturing via printing could address this technological need by allowing low-cost integration of energy materials over large areas and in new 3D geometries. We investigate the physics of printing metal halide perovskite solar cells, showing strategies for designing fluid precursor inks that can enable large-area patterning at state-of-the-art speed and uniformity via flexography. Rapid optoelectronic characterization reveals fundamental links between film uniformity, drying kinetics, and photovoltaic performance. Towards the goal of sustainable fabrication of electronics and electrolyzers, we present strategies for printing high performance metal oxides in 2D and 3D. We introduce a roll-based method for rapid, low-temperature synthesis and van der Waals transfer of these high-mobility wide bandgap semiconductors via Cabrera Mott oxidation of liquid metal interfaces. Finally, we demonstrate applications of metal oxides (CuOx, CoOx) in 3D printed electrocatalytic (OER, HER) microlattice electrodes that leverage enhanced mass-transport of bubbles and electrolyte via engineered porosity.

Professor William Scheideler graduated summa cum laude from Duke University in 2013 with double BSE degrees in electrical engineering and biomedical engineering. He completed his PhD as an NSF graduate research fellow in electrical engineering at the University of California, Berkeley, where his doctoral thesis explored scalable nanomanufacturing of metal oxide electronics. He then completed his postdoctoral studies in the Department of Materials Science and Engineering at Stanford University, where he studied scalable fabrication of perovskite solar cells. Scheideler joined the faculty of Dartmouth College’s Thayer School of Engineering as an assistant professor in 2019, launching the SENSE (Scalable Energy and Nanomaterial Electronics) Laboratory. His current research interests include 3-D nanomanufacturing and 2D materials for electronics and energy applications. In 2023, William was a recipient of the SME’s Delcie Durham Outstanding Young Manufacturing Engineer Award recognizing his research in advanced manufacturing.
