Abstract

In this study, the surface modified TiO₂ nanoparticles have been prepared through microwave-assisted reaction with oleic acid as surfactant. The as-synthesized TiO₂ nanoparticles reveal uniform particle size distribution and high dispersibility in organic solvents which can be easily integrated into solution-process. The organic capped TiO₂ (OC-TiO₂) has been applied as filler for LED encapsulant and electron collection layer for organic solar cells. With 1.0 wt% loading of TiO₂ nanoparticles, the refractive index (RI) of TiO₂/silicone composites increase from 1.51 for neat silicone to 1.575. As a result, a high-power LED encapsulated with this composite showed more than 9% increase in the light output. Moreover, the organic solar cell with the OC-TiO₂ as electron collection layer shows an enhanced long-term durability due to the hydrophobic property of OC-TiO₂.
