A new series of organic dyes based on indeno[1,2-b]indole have been synthesized and applied in dye-sensitized solar cells (DSSCs) for the first time. These four dyesQX11–14are constructed to a D–π–A type structure consisting of an indeno[1,2-b]indole donor and a cyanoacrylic acid acceptor/anchoring group. Different π-bridges (thiophene and furan) and different alkyl groups (ethyl and hexyl) are involved to tune the photoelectric properties. Their optical, electrochemical, and photovoltaic properties, as well as the density functional theory calculations have been systematically investigated, indicating these four dyes are all capable as photosensitizers. The four dyes all show good DSSC performances and a highest power conversion efficiency up to 7.64% with aJscof 15.8 mA cm−2and aVocof 763 mV has been achieved by the dyeQX12with a furan π-bridge and a pair of ethyl groups, which reaches 95% of the commercialN719dye (8.07%) under AM 1.5G illumination. This result reveals indeno[1,2-b]indole is a promising electron donor to construct efficient organic dyes for DSSCs.
