Abstract

An interparticle-binding agent, or "nanoglue," was prepared for the fabrication of well-interconnected TiO₂ photoelectrodes in dye-sensitized solar cells (DSSCs) sintered at low temperature. This nanoglue consisted of pure anatase particles approximately 5 nm in diameter dispersed in alcoholic solvent. When mixed with TiO₂ particles 21 nm in diameter, the nanoglue induced interparticle chemical bridging via the condensation of hydroxyl groups on surfaces of TiO₂ particles. The efficiency of nanoglue-based DSSCs was improved by approximately 25% compared to non-nanoglue-based DSSCs. This improvement was mainly ascribed to enhanced interparticle connections due to the presence of the 5 nm TiO₂ particles in nanoglue.
