Abstract

Microsecond dye-regeneration kinetics was observed in efficient solid state dye-sensitized solar cells using photoelectrochemically deposited poly(3,4-ethylenedioxythiophene (PEDOT) hole conductors using transient absorption spectroscopy. The dye-regeneration rate is orders of magnitude slower than the case using the I^-/I₃ ^- redox couple or commonly used small molecule hole conductor and is attributed to the low dye to PEDOT ratio within the films.
