Novel quasi‐solid‐state dye‐sensitized solar cell based on monolayer capped TiO 2 nanoparticles framework materials

Dodecylbenzenesulfonate (DBS)‐capped TiO 2 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 TiO 2 nanoparticles interacting with the liquid solvent, the dye sensitized solar cell based on such DBS‐capped TiO 2 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.
