Comparison of Three Different Click Reaction Methods for the Synthesis of Fluorene-Based Polymers and Performance in Quasi-Solid-State DSSCs

The three different methods of click reaction has been used to synthesize fluorene-based click polymers and compared its effect on polymer electro-optical properties as well as photovoltaic performances in DSSCs. The DSSCs devices with configuration of SnO2:F/TiO2/N719 dye/quasi-solid-state electrolyte/Pt devices were fabricated using these click polymers as a quasi-solid-state electrolyte components. Among the devices, the catalyzed click polymer composed DSSCs device exhibited high power conversion efficiency (PCE) of 4.62% under AM 1.5G illumination. These click polymers are promising materials for device application and the Cu-I-catalyst 1,3-dipolar cycloaddition click reaction is an efficient synthetic methodology.
