Heteroleptic copper(i)–polypyridine complexes as efficient sensitizers for dye sensitized solar cells†
Abstract
The synthesis and the physico-chemical characterization of HETPHEN based heteroleptic copper(I)–bis(diimine) complexes are reported. For TiO2 based dye sensitized solar cells (DSCs), the latter display impressive photoconversion efficiencies (PCEs), unprecedented for first row transition metal coordination complexes.
