Nanostructured Electrodes - A Survey of Recent Result from Our Laboratory
on Research Related to Dye-sensitized Solar Cells
Sten-Eric Lindquist
Uppsala University
In this survey the conditions for an efficiency dye-sensitized solar cell
(DSC) [1] will be discussed. The following questions will be asked: What
can we do to make DSCs more efficient? Which are the limiting factors?
The solar energy efficiency of a DSC is a complex function of many
interrelated parameters such the internal surface area of the
nanostructured metal oxide electrode (NS MOE), the size and absorption
coefficient of the dye, the particle sized, porosity and morphology of the
NS MOE[2]. Moreover, its has been shown that the efficiency of a DSC is
strongly related to the components in the electrolyte. Not only the
character of the redox couple but also the components in the supporting
electrolyte are affecting the charge transport as well as the interfacial
kinetics[3]. Results from our laboratory will be discussed, in particular
the charge transport in some different nanostructured MO
electrode-electrolyte system[4].
