Abstract

A high molar extinction coefficient heteroleptic ruthenium complex, incorporating an electronrich hexylthio-terminal chain, has been synthesized and demonstrated as an efficient sensitizer for dye-sensitized solar cells. With this new sensitizer excellent power conversion efficiency is 11.5% and 4.7% obtained under an irradiation of full sunlight (air mass 1.5 global) in combination with a volatility electrolyte and solid state hole transporting material, respectively. The devices with low volatility electrolyte showed good stability under visiblelight soaking at 60 °C during 1000 h of accelerated tests.
