Shell-in-shell TiO2 hollow spheres synthesized by one-pot hydrothermal method for dye-sensitized solar cell application

Wu, Xia, Lu, Gao Qing (Max), Wang, Lianzhou·2011·Energy & Environmental Science

Abstract

A new type of shell-in-shell TiO2 hollow spheres (S@S-TiO2) featuring excellent light scattering properties were synthesized by a facile one-pot hydrothermal method followed by calcination. Various characterizations revealed that the ratio of sucrose to TiF4 in the reagents plays a key role in controlling the hollow architecture and shell thickness of the resultant S@S-TiO2 structure. The excellent light scattering property of S@S-TiO2 makes it a promising candidate for use as the scattering layer in dye-sensitized solar cells. A bilayer structured photoelectrode consisting of the S@S-TiO2 film as a scattering layer on top of the benchmark TiO2 P25 thin film exhibited an overall conversion efficiency of 9.10% under AM-1.5G one sun light intensity, in comparison with the 7.65% efficiency for a pristine P25 photoanode.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
