“…Recently, we reported the effect of plasma treatment on the structural and surface properties of TiO 2 aerogel, their overall influence on DSSC performance [27,28]. The microstructure of SiO 2 -TiO 2 hybrid aerogels were studied and used as a photoanode in DSSC [29,30]. The microstructure and morphology of the aerogel are governed by the threedimensional network formations during sol-gel synthesis.…”

“…SiO 2 /TiO 2 hybrid aerogel is used as a photoanode material in DSSC and exhibits a power conversion efficiency of 9.41%. The high efficiency is due to the increase in shortcircuit current achieved by high dye loading and light scattering property induced by aerogel microparticles [128]. Gao et al first synthesized ZnO aerogels through epoxide initiated sol-gel method followed by supercritical drying [129].…”

Aerogels are 3-D nanostructures of non-fluid colloidal interconnected porous networks consisting of loosely packed bonded particles that are expanded throughout its volume by gas and exhibit ultra-low density and high specific surface area. Aerogels are normally synthesized through a sol-gel method followed by a special drying technique such as supercritical drying or ambient pressure drying. The fascinating properties of aerogels like high surface area, open porous structure greatly influence the performances of energy conversion and storage devices and encourage the development of sustainable electrochemical devices. Therefore, this review describes on the applications of inorganic, organic and composite aerogel nanostructures to dye-sensitized solar cells, fuel cells, batteries and supercapacitors accompanied by the significant steps involved in the synthesis, mechanism of network formation and various drying techniques.

“…This is because the meso-50 film had a higher number of macropores than the meso-75 film (refer to the BJH pore distribution in Figure S3) which could also serve as scattering centres. 35 The inset in Figure 6 shows the appearance of the meso-X photoanodes. For the meso-0 film, the words on the sheet beneath the photoanode can still be identified, whereas the words under other samples became gradually less clear as the weight ratio of meso-TiO 2 was increased, and are completely obscured by the meso-100 film because of the intense light scattering effect of the micrometre sized aggregates of meso-TiO 2 .…”

KJ 2015, 'Ordered mesoporous particles in titania films with hierarchical structure as scattering layers in dye-sensitized solar cells'ABSTRACT: This work aimed to understand the relationship between the physical properties of scattering particle layers in Dye Sensitized Solar Cells (DSSC) to their performance, to assist optimization of this component of the DSSC. Highly ordered anatase 2D-hexagonal mesoporous titania (meso-TiO 2 ) nanoparticles with a high surface area and large pore size were fabricated.Meso-TiO 2 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 DSSC. The influence of meso-TiO 2 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, had higher surface areas and greater light scattering effects when meso-TiO 2 was incorporated. The performance of these scattering layers in relatively large, 1cm 2 area, DSSC was studied to link cell performance to the detailed physical properties of the meso-TiO 2 /nanoparticle films. The optimum composition of scattering layers was obtained by mixing 50 wt.% meso-TiO 2 with titania nanoparticles.
