Series of dyes containing a fluorene moiety in the spacer have been designed, synthesized, and characterized. These dipolar compounds contain an arylamine or cycloalkylamine as the electron donor, a 2-acrylic acid as the electron acceptor, and a conjugated spacer between the donor and the acceptor. We designed variety of the conjugation length with one fluorine moiety as well as the innovated synthesis process for industrial mass production. The device performance data were obtained under AM 1.5 illumination. and the efficiency of DSSCs exhibited good performance (?), ranging from 2.22 %-4.76 %, which reached 40%-87 % with respect to that of the standard cell from N719-based device fabricated under the same condition.Beside the organic DSSC dyes development, Everlight R&D center also concentrate on the improvement of novel Ruthenium dyes. The performance results indicated that higher efficiencies compared to the standard reference dye, N719 and Z907.
