Dye-sensitized solar cells (DSSCs) have emerged as efficient and promising alternative to conventional Si-based and thin-film photovoltaic technologies because of their low cost and high-power conversion efficiencies [1]. Since light-harvesting is the key process in the DSSC device, much effort has been devoted to increasing the absorptivity of the dyes [1, 2]. The polypyridyl ruthenium (II) complex-based dyes have remarkable performance originating from their strong absorption in the visible region and chemical stability of photoexcited states, and oxidized form [2]. Herein, the new binuclear ruthenium (II) complex (BiRu Dye) with an alkyl spacer (-CH2-) was designed and synthesized and in order to obtain insight into potential of this complex for used as dye in DSSC, its electrochemical properties were investigated and compared with N3 (Ru(H2dcbpy)2(NCS)2) as standard dye
