Comparison of Three Different Click ReactionMethods for the Synthesis of Fluorene-BasedPolymers and Performance in Quasi-Solid-StateDSSCs

The three different methods of click reaction has been used to synthesize fluorene-based clickpolymers and compared its effect on polymer electro-optical properties as well as photovoltaicperformances in DSSCs. The DSSCs devices with configuration of SnO2:F/TiO2/N719 dye/quasi-solid-state electrolyte/Pt devices were fabricatedusing these click polymers as a quasi-solid-stateelectrolyte components. Among the devices, thecatalyzed click polymer composed DSSCs deviceexhibited high power conversion efficiency (PCE)of 4.62% under AM 1.5G illumination. These clickpolymers are promising materials for deviceapplication and the CuI-catalyst 1,3-dipolarcycloaddition click reaction is an efficient syn-thetic methodology.
