I am only finding the above mentioned anchors repeatedly. Is it possible to get any group which can be part of the conjugation and a good binder with TiO2.
Refer this article "What Is the Best Anchoring Group for a Dye in a Dye-Sensitized Solar Cell?. J. Phys. Chem. Lett., 2012, 3 (11), pp 1531–1535" you may get so many novel anchoring group in the dye which is used in DSSC.
find the review articles about the DSSC there you can able to easily understand the basic principles and application. Dye-Sensitized Solar Cells, Chem. Rev., 2010, 110 (11), pp 6595–6663; Solar Energy Conversion by Dye-Sensitized Photovoltaic Cells; Inorg.
