Influence of Sn source on the performance of dye-sensitized solar cells based on Sn-doped TiO2 photoanodes: A strategy for choosing an appropriate doping source

The Synthesis of Nb-doped TiO2 Nanoparticles for Improved-Performance Dye Sensitized Solar Cells

“…In general, a good TiO 2 photoanode should possess a high electrical conductivity and a tight chemical bonding with dye, and match the dye's lowest unoccupied molecular orbital (LUMO). To further improve the performance of TiO 2 electrode, the incorporation of metal (Er, Yb, Zn, Co, Nb) as a dopant in TiO 2 has been reported to use as a favorable electron-transfer mediator in photovoltaic devices [8][9][10][11]. Among them, Nb-doped TiO 2 with its low cost, nontoxicity, earth abundance, and both thermal and chemical stability has received great attention as a new promising alternative to DSSCs.…”

Facile synthesis of TiO 2 and Sn‐TiO 2 heterostructures based photoanodes for dye sensitized solar cells

“… 44 Comparison between the lattices parameters of TiO 2 @Sn‐TiO 2 and Sn‐TiO 2 @TiO 2 indicates compression in a. This compression makes crystalline structure more suitable to minimize charge recombination 45 . The ionic radius of Sn 4+ is larger than the lattice Ti 4+ , therefore the lattice parameters tend to increase after doping 46 …”

Development of TiO2 Nanomaterials and Dyes Selection (using DFT) for DSSC Applications –A Stepwise Review

“…This implies that onedimensional structures will benefit more from dopants that increase dye adsorption, whereas nanoparticle assemblies will benefit more from doping that leads to increased charge transport. The dopant source can also influence the effectiveness of doping and it has been shown that organic sources lead to better performances than inorganic salts [80]. Furthermore, doping influences the anatase to rutile phase transition [81].…”
