What is the science behind the de-aggregation of organic dye using deoxycholic acid (DCA)?

12 December 2015 1 9K Report

How does the DCA works to lessen the aggregation of organic and other dyes to be used in a dye sensitized solar cell. I want to understand its effect on the dye or interaction with the dye to decrease the aggregation

Sreenivasarao Vepachedu

Deoxycholic acid acts as a detergent and solubilizes fats. DCA acts as a coadsorbant reducing the dye aggregation. The coadsorption of DCA suppresses charge recombination.
