Abstract:
 
  Interfacial electron transfer is ubiquitous in solar cells and batteries, but with different requirements. Unidirectional diode-like behavior is desirable in solar cells, while reversible electron transfer is crucial for rechargeable batteries. In this talk, we will present our recent progress in redox control for metal-air batteries and dye-sensitized solar cells. Three stories will be discussed: (1) molecular and solid-state materials for p-type dye-sensitized solar cells and solar fuels, (2) one-electron K-O2 batteries, and (3) integrated solar batteries.
