Conductivity of surface modified TiO 2 dope nanocomposites

Theoretical and experimental studies on DC conductivity and temperature-dependent AC conductivity of poly(butyl methacrylate)/Nd-TiO2 nanocomposites

“…[11][12][13] The insulating polymers can be converted into the conducting one by the addition of nanoparticles at the percolation threshold. 14,15 Nanocomposites prepared by mixing the organic polymer with inorganic metal oxide nanoparticles got significant attention due to their excellent electrical and optical properties. [6][7][8][9][10][11][12][13][14][15][16][17][18] Among the metal oxide nanoparticles, TiO 2 is one of the most important nanoparticles because of its unique electrical and optical properties.…”

Enhanced performance of dye-sensitized solar cells aided by Sr,Cr co-doped TiO 2 xerogel films made of uniform spheres

“…Although conventional mesoporous photoanodes containing 20 nm TiO 2 nanoparticles enjoy high dye-loading ability, they suffer from such impediments as weak electron injection and high recombination rate of photogenerated electrons and holes. In order to improve the power conversion efficiency of DSCs, a broad spectrum of research focused on incorporating foreign transition and alkaline earth ions into the TiO 2 lattice [2][3][4][5][6][7]. Simultaneously introduction of both transition and alkaline earth ions into TiO 2 matrices has rapidly raised interest because improves photocatalytic activity as compared to doping with a one single element [8,9].…”

Crystal structure, optical and electrical characteristics of rutile $$\hbox {TiO}_{2}$$ nanocrystallite-based photoanodes doped with $$\hbox {GeO}_{2}$$

“…One of the compelling methods to enhance the conversion efficiency of TiO 2 DSSC photoanodes is by doping TiO 2 with transition element ions or alkaline earth ions [5][6][7][8][9][10]. The transition element ions lead to expanding the absorption edge of the TiO 2 to visible-light region by embedding a sub-band into the main band gap.…”
