Three new terpyridine-based ruthenium complexes, named as MC124, MC125 and MC127, were synthesized and employed as sensitizers in dye sensitized solar cells.

Abstract

Three new terpyridine-based ruthenium complexes, named as MC124, MC125 and MC127, were synthesized and employed as sensitizers in dye sensitized solar cells. The MC dyes were characterized with experimental techniques followed by theoretical calculations. The promising optical properties with higher molar extinction coefficients compared to N749 prototypical dye, and suitable positioning of energy levels prompted us to employ these dyes in working devices. When used in conjunction with liquid I-/I3- redox electrolyte, the MC dyes have shown modest performances, with a maximum PCE of 2.3% reached with MC124 in combination of CDCA used as co-adsorbent.
