[资源] 染料敏化TiO2光致电子转移的理论研究

Theoretical Studies of Photoinduced Electron Transfer in Dye-Sensitized TiO2

Annu. Rev. Phys. Chem. 2007. 58:143–84

Abstract
This review describes recent research into the properties of the
chromophore-TiO2 interface that forms the basis for photoinduced
charge separation in dye-sensitized semiconductor solar cells. It focuses
particularly on an atomistic picture of the electron-injection
dynamics. The interface offers an excellent case study, pertinent as
well to a variety of other photovoltaic systems, photo- and electrochemistry,
molecular electronics, analytical detection, photography,
and quantum confinement devices. The differences between
chemists’ and physicists’ models for describing molecules and bulk
materials, respectively, create challenges for the characterization of
interfaces that include both of these components.We give an overall
picture of the interface by starting with a description of the
properties of the chromophores and semiconductor separately, and
then by discussing the coupled system, including the chromophoresemiconductor
binding, electronic structure, and electron-injection
dynamics. Explicit time-dependent modeling is particularly valuable
for an understanding of the ultrafast electron injection because
it shows a variety of individual injection events with well-defined
dynamical features that cannot be made apparent by an average
reaction-rate description.
