Abstract
A heteroleptic polypyridyl ruthenium complex, cis-Ru(4,4′-bis(5-octylthieno[3,2-b]thiophen-2-yl)-2,2′-bipyridine)(4,4′-dicarboxyl-2,2′-bipyridine)(NCS)2 , with a high molar extinction coefficient of 20.5 × 103 M−1 cm−1 at 553 nm has been synthesized and demonstrated as a highly efficient sensitizer for a dye-sensitized solar cell, giving a power conversion efficiency of 10.53% measured under an irradiation of air mass 1.5 global (AM 1.5G) full sunlight.Keywords
