Ordered Mesoporous Particles in Titania Films with Hierarchical Structure as Scattering Layers in Dye-Sensitized Solar Cells
(2015) In Journal of Physical Chemistry C 119(39). p.22552-22559- Abstract
This work aimed to understand the relationship between the physical properties of scattering particle layers in dye-sensitized solar cells (DSSCs) and their performance, to assist optimization of this component of the DSSC. Highly ordered anatase 2D-hexagonal mesoporous titania (meso-TiO2) nanoparticles with a high surface area and large pore size were fabricated. Meso-TiO2 was used as scattering particles and mixed with titania nanocrystallites at weight proportions ranging from 0 to 100%. Films made from the composites were used as scattering layers in DSSCs. The influence of meso-TiO2 proportion on the structure, morphology, and optical properties of the films were investigated. The results show that... (More)
This work aimed to understand the relationship between the physical properties of scattering particle layers in dye-sensitized solar cells (DSSCs) and their performance, to assist optimization of this component of the DSSC. Highly ordered anatase 2D-hexagonal mesoporous titania (meso-TiO2) nanoparticles with a high surface area and large pore size were fabricated. Meso-TiO2 was used as scattering particles and mixed with titania nanocrystallites at weight proportions ranging from 0 to 100%. Films made from the composites were used as scattering layers in DSSCs. The influence of meso-TiO2 proportion on the structure, morphology, and optical properties of the films were investigated. The results show that the films became more porous, with a larger surface roughness, and had higher surface areas and greater light-scattering effects when meso-TiO2 was incorporated. The performance of these scattering layers in relatively large, 1 cm2 area, DSSCs was studied to link cell performance to the detailed physical properties of the meso-TiO2/nanoparticle films. The optimum composition of scattering layers was obtained by mixing 50 wt % meso-TiO2 with titania nanoparticles.
