Co-ping with being sensitive: Two thiocyanate-free ruthenium(II) sensitizers, TFRS-41 and TFRS-42 with distinctive dialkoxyphenyl thienyl substituents are tested for potential applications in dye-sensitized solar cells with a [Co(bpy)3]2+/3+-based (bpy=2,2′-bipyridine) electrolyte. Through proper control of peripheral substituents good cell performance characteristics are recorded for sensitizer TFRS-42.
