Hierarchically assembled microspheres consisting of nanosheets of highly exposed (001)-facets TiO₂ for dye-sensitized solar cells

Abstract

Mono-dispersed 2D nanosheets of 3D microspheres nanostructure was synthesized. It shows highly exposed (001)-facets (ca. 82%) and high surface area (112.2 m2 g−1). 11.13%-efficient DSSC is obtained with TiO2 microspheres working electrode.

Mesocrystal TiO2 films: in situ topotactic transformation and application in dye-sensitised solar cells

“…From eqn (2), the position of conduction band of TiO 2 also alters the value of R 0 therefore R rec when different TiO 2 is applied as photoanodes. Even though CB edge shis of TiO 2 with exposed {001} facets have been detected and reported in some published reports, 58 the impact of this on R rec is not signicant here by comparing cell F and cell D. Electron lifetime calculated from s n ¼ R rec  C m was also plotted versus applied potential (Fig. 8c) and total electron concentration (Fig.…”

Transparent Cobalt Selenide/Graphene Counter Electrode for Efficient Dye-Sensitized Solar Cells with Co2+/3+-Based Redox Couple

“…49,56,57 TiO 2 nanosheets were prepared following previous reports as well. 58,59 More information was attached in the electrospray ionization process. The electrolyte precisely consisted of 0.21 M [Co(bpy) 3 ](TFSI) 2 , 0.068 M [Co(bpy) 3 ](TFSI) 3 , 0.95 M tBP, and 0.055 M LiTFSI in ACN.…”

Effect of triblock copolymers on crystal growth and the photocatalytic activity of anatase TiO2 single crystals

“…[22][23][24] For growth controlling agents in particular, they are very important for the adjustment of grain size, crystal surface characteristics and crystal dispersion in the synthetic process. 25,26 Generally, the commonly used crystal growth control agents are surfactants, silica templates, and dispersants. 27,28 In addition, with further study of the crystal growth mechanism, more and more additives have been found and have been proved to affect the growth rate and morphology of the crystals.…”
