(A) Time-resolved transient absorption spectra of ITO/CuI electrodes in 0.1 M Bu4NPF6/DCM electrolyte after 387 nm laser pulse excitation (4 μJ cm–2) at an applied potential of +0.2 V vs Ag/AgCl. (B) Bleach recovery profiles monitored at 412 nm at applied potentials from −0.1 to +0.6 V vs Ag/AgCl. (C) Potential dependence of the determined lifetimes. The recovery profiles in (B) were fitted with a monoexponential decay. See article  for more details.
