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(-)/I(3)(-) redox couple or commonly used small molecule hole conductor and is attributed to the low dye to PEDOT ratio within the films.
利用瞬态吸收光谱法观察到在使用光电化学沉积聚（3,4-亚乙基二氧噻吩（PEDOT）空穴导体的高效固态染料敏化太阳能电池中存在微秒级染料再生动力学。与使用 I(-)/I(3)(-)氧化还原对或常用小分子空穴导体的情况相比，染料再生速率慢了几个数量级，这归因于薄膜内染料与 PEDOT 的比例较低。
