Iodine in Dye-Sensitized Solar Cells
2014 (English)In: Iodine Chemistry and Applications, Wiley-Blackwell, 2014, Vol. 9781118466292, 501-512 p.Chapter in book (Other academic)
This chapter discusses the role of the iodine-based redox systems in the three components of the dye-sensitized solar cell (DSSC) separately; at the photoelectrode, at the counterelectrode, and finally in the electrolyte. It should be noted that essentially all information communicated refers to n-type DSSC devices, and that similar descriptions regarding the role of iodine is also be made for p-type DSSCs. Regeneration of the oxidized dye at the photoelectrode is a central process in the DSSC. Many different counterelectrode materials may be used in DSSC devices, such as conducting metal oxides, carbon materials, and metals. The DSSC device is conceptually quite simple, but the optimization of the device as a whole is a delicate matter involving several intimate and delicately dependent processes, in particular at the electrode surfaces. Iodide was not the only halide to be used in DSSCs. Bromide, with its oxidized companion-the tribromide ion-represents an alternative.
