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

Abstract

Abstract 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 SnO 2 :F/TiO 2 /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. magnified image
