An aerosol OT (AOT; sodium bis(2-ethylhexyl)sulfosuccinate)/water system coupled with I3/I electrolyte enables the control of the concentration of the redox couples through the hydrogen-bonding association between the AOT and the carboxy group of the dye in dye-sensitized solar cells (DSCs), as demonstrated by Taiho Park, Hyun Myung Jang, and co-workers on page 1344. This novel concept provides insight into the regeneration and recombination kinetics and allows for the development of highly efficient DSCs.
