Low-cost poly (3,4 ethylenedioxythiophene) (PEDOT) films with a high electronic conductivity of 1021 S/cm were successfully deposited via iron oxide-based vapor-phase polymerization and used as a counter electrode (CE) in dye-sensitized solar cells for the first time. Reaching a high efficiency of 8.4%, the CE showed outstanding catalytic activity in iodine/triiodide (I–/I3–) reduction, with a […]
D’Arcy and colleagues, including Washington University graduate student Hongmin Wang, first author of the new study, showed how to convert red bricks into a type of energy storage device called a supercapacitor. The red pigment in bricks — iron oxide, or rust — is essential for triggering the polymerisation reaction. The authors’ calculations suggest that […]
New methods for engineering microsupercapacitors developed by Julio M. D’Arcy, assistant professor in the Department of Chemistry, and collaborators at Washington University’s Institute of Materials Science & Engineering combine conventional microfabrication techniques with cutting-edge polymerization. The team’s microsupercapacitors show exceptional electrical conductivity and energy density, producing the highest such values of any conducting polymer-based microsupercapacitors. The results are published […]
A drugstore solution for synthesizing stable semiconducting polymers D’Arcy Lab develops an elegant, inexpensive approach that uses aerosolized water vapor as a template for creating uniform plastic nanoparticles. Current methods for producing conducting plastics typically deposit the material onto a flat surface, resulting in differences in shape between the top and bottom of the particles. […]
Fall 2019 LEAP Cycle Winners Announced D’Arcy Lab wins 2019 Leap Funding On December 5, 2019, for the first time the Skandalaris Center’s Leadership and Entrepreneurial Acceleration Program, better known as LEAP, announced the funded teams the day of cycle finals. Twenty-five teams from a variety of backgrounds presented their projects and were judged on […]
