Halos show the path to perfection: peripheral iodo-substituents improve the efficiencies of bis(diimine)copper(i) dyes in DSCs

DSCs containing simple copper(i) dyes with peripheral halo (X) ligands give global efficiencies >3% for X = I; a new strategy for stepwise surface dye assembly is demonstrated.

Copper(i)-based dye-sensitized solar cells with sterically demanding anchoring ligands: bigger is not always better

DSC performances of [Cu(N⁁N_anchor)(N⁁N_ancillary)]⁺ dyes with Ph or Me groups adjacent to the copper-binding site in N⁁N_anchor are compared; electrodes with dyes that bleach are regenerated by reimmersion in dye baths containing N⁁N_anchor.

Influence of a co-adsorbent on the performance of bis(diimine) copper(i)-based dye-sensitized solar cells

The effects of adding chenodeoxycholic acid to copper(i) bis(diimine) dyes in DSCs has been studied, as well as a new stepwise procedure for TiO₂-bound dye assembly.

Programmed assembly of 4,2′:6′,4′′-terpyridine derivatives into porous, on-surface networks

4,2′:6′,4′′-Terpyridine building blocks self-assemble into hydrogen-bonded domains; addition of copper atoms results in an on-surface transformation into a coordination network.
