A new terpyridine cobalt complex redox shuttle for dye-sensitized solar cells

A new cobalt-terpyridine redox shuttle based on a substituted terpyridine ligand, has been synthesized, characterized, computationally investigated and tested in photovoltaic devices. The new redox shuttle is compared to the reference [Co(bpy)3]2+/3+, analyzing the effect of different counterions.
