Novel quasi‐solid‐state dye‐sensitized solar cell based on monolayer capped TiO2 nanoparticles framework materials

Abstract
Dodecylbenzenesulfonate (DBS)‐capped TiO2 nanoparticles have been synthesized and employed in dye‐sensitized solar cells to form a quasi‐solid state electrolyte. Owing to the long alkyl‐chain capping around the TiO2 nanoparticles interacting with the liquid solvent, the dye sensitized solar cell based on such DBS‐capped TiO2 nanoparticle framework material gel electrolyte shows higher stability compared with the non‐capped one in the long‐term application and gives a comparable overall efficiency of 6.3% at AM 1.5 illumination.
