Investigation on the coordination between methylpyridine additives and the [Cu(dmp)2]2+/+ redox couple and its improvement towards the stability of the dye-sensitized solar cells

Abstract

The position of the methyl group in methylpyridine derivatives plays an important role in the copper(ii) coordination mechanism and their electrochemical properties relate to the regeneration process of [Cu(dmp)2]2+ at the counter electrode/electrolyte interfaces.
