Abstract
The central theme of the Ardo Group's research program is to understand and control reaction mechanisms at interfaces, with the goal of maximizing energy-conversion efficiency for realistic applications, including solar fuels devices, photovoltaics, solar seawater desalination, redox flow batteries, and fuel cells.

Asymmetry is the key characteristic responsible for light-induced charge separation and current rectification; it is present in semiconductors, biological membranes, and molecular donor–chromophore–acceptor complexes. Members of the Ardo Group design and control asymmetry through modeling, synthesis, and engineering of molecule–material structures. The electrochemical, photoelectrochemical, and photophysical properties of hard and soft material interfaces are manipulated via molecular functionalization and electrostatic engineering. New materials and molecules are being investigated, including photoacidic materials, multiple-electron-transfer oxidation catalysts, infrared-absorbing dyes, chemically modified surfaces, and ion-conducting metal–organic frameworks. The results from each study are pertinent to fundamental electrochemistry and charge-transfer, energy-transfer, and ion-transfer phenomena.

Generally, the Ardo Group's research consists of five main project categories:

  • Artificial Light-Driven Ion Pumps: Ionic energy-conversion interfaces and photoinduced ion transfer
  • Sunlight-Driven Charge Accumulation: A paradigm shift for dye-sensitized solar-energy-conversion devices
  • Next-Generation Thin-Film Solar Cells: Leveraging organic dications to combat instability
  • Solar-Energy Conversion and Storage Systems: New device architectures and chemistries
  • Non-Noble-Metal Electrocatalysis: Locally benign environments and new ion-exchange mechanisms

The Ardo Group is well-suited for students and postdoctoral scholars with various backgrounds and expertise, spanning the disciplines of chemistry, materials science, chemical engineering, physics, electrical engineering, and biology.
