Electrodeposition and Low‐Temperature Post‐Treatment of Nanocrystalline SnO₂ Films for Flexible Dye‐Sensitized Solar Cells

Abstract

SnO2porous films were electrodeposited on Ti substrate using pulse-potential technique. These deposited films were dealt with different post-treatments. The effects of the post treatments were investigated through X-ray diffraction, FE-SEM, and Raman spectra. These investigations showed that crystal nanoporousSnO2films were obtained through low-temperature post-treatment process. The photoelectric conversion efficiency of theSnO2film treated with both the water vapour treatment and ultraviolet illumination was improved to be 0.35% which was comparable with the conversion efficiency of the film sintered at550∘C.

Engineering flexible dye-sensitized solar cells for portable electronics

“…In preparation of FDSSCs, plentiful metal oxides have been investigated as the photoanode material in the rigid DSSCs, such as TiO2, ZnO, SnO2, Nb2O5, WO3, SrTiO3, In2O3, and Zn2SnO4 [38][39][40][41][42]. However, the major photoanode materials applied in the FDSSCs are limited on TiO2, ZnO, SnO2, Zn2SnO4 [43][44][45][46], plus a few reports on SnO2 and Zn2SnO4.…”

“…The electron transport materials used in FDSSCs are TiO 2 [81][82][83][84], SnO 2 [85], ZnO [86,87], and Zn 2 SnO 4 [88] etc. Among them, TiO 2 is the most widely used electron transport material in FDSSCs due to its nontoxicity, stable, large band gap and ideal Fermi level.…”
