Highly Efficient Plasmon-Enhanced Dye-Sensitized Solar Cells through Metal@Oxide Core–Shell Nanostructure

Qi, Jifa, Dang, Xiangnan, Hammond, Paula T., Belcher, Angela M.·2011·ACS Nano

Abstract

We have investigated the effects of localized surface plasmons (LSPs) on the performance of dye-sensitized solar cells (DSSCs). The LSPs from Ag nanoparticles (NPs) increase the absorption of the dye molecules, allowing us to decrease the thickness of photoanodes, which improves electron collection and device performance. The plasmon-enhanced DSSCs became feasible through incorporating core-shell Ag@TiO(2) NPs into conventional TiO(2) photoanodes. The thin shell keeps the photoelectrons from recombining on the surface of metal NPs with dye and electrolyte and improves the stability of metal NPs. With 0.6 wt % Ag@TiO(2) NPs, the power conversion efficiency of DSSCs with thin photoanodes (1.5 μm) increases from 3.1% to 4.4%. Moreover, a small amount of Ag@TiO(2) NPs (0.1 wt %) improves efficiency from 7.8% to 9.0% while decreasing photoanode thickness by 25% for improved electron collection. In addition, plasmon-enhanced DSSCs require 62% less material to maintain the same efficiency as conventional DSSCs.

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.
