ZnO nanowire networks featuring excellent charge transport and light scattering properties are grown in situ within TiO2 films. The resultant TiO2/ZnO composites, used as photoanodes, remarkably enhance the overall conversion efficiency of dye-sensitized solar cells (DSSCs) by 26.9%, compared to that benchmark Detailed facts importance specialist readers published ”Supporting Information”. Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted authors....
Nanoribbon- and nanowire-based field-effect transistor (FET) biosensors have stimulated a lot of interest. However, most FET were achieved by using bulky Ag/AgCl electrodes or metal wire gates, which prevented the from becoming truly wearable. Here, we demonstrate highly sensitive conformal In2O3 nanoribbon with fully integrated on-chip gold side gate, been laminated onto various surfaces, such as artificial arms watches, enabled glucose detection in body fluids, sweat saliva. The...
Abstract Copper chalcogenide nanostructures (e.g. one‐ dimensional nanotubes) have been the focus of interest because their unique properties and great potential in various applications. Their current fabrications mainly rely on high‐temperature or complicated processes. Here, with assistance theoretical prediction, we prepared Cu 2− x E (E=S, Se) micro‐/nanotubes (NTs) a hierarchical architecture by using copper nanowires (Cu NWs), stable sulfur selenium powder as precursors at room...
Ultrathin SnO2 nanosheets were prepared by a hydrothermal method using SnF2 and methenamine as precursor morphology controlling agent, respectively. Structural characterizations indicate that these ultrathin having thickness of approximately 4–6 nm can assemble into three-dimensional, flowerlike architecture. Due to the higher electron mobility enhanced light-scattering effect hierarchical structures, dye-sensitized solar cells (DSSCs) based on such architectures exhibit much cell...
Cuboid-like anatase TiO2 single crystals bounded by {001} and {100} facets have been successfully synthesized with HCl as a synergistic capping agent together HF, under the guidance of theoretical calculations. DFT calculations suggest that preferred replacement HF at (100) well its favorable adsorption provide unique stabilization effect on formation cuboid-like TiO2.
Light harvesting and electron recombination are essential factors that influence photovoltaic performance of quantum dots sensitized solar cells (QDSSCs). ZnO hollow microspheres (HMS) as architectures in QDSSCs beneficial improving light scattering, facilitating the enhancement efficiency. However, this advantage is greatly weakened by defects located at surface HMS. Therefore, we prepared a composite microsphere structure consisting HMS coated TiO2 layer obtained immersing TiCl4 aqueous...
ZnxCd1-xSe@ZnO hollow spheres (HS) were successfully fabricated for application in quantum dot sensitized solar cells (QDSSCs) based on ZnO HS through the ion-exchange process. The sizes of could be tuned from ~300 nm to ~800 using pre-synthesized by different carbonaceous as templates. photovoltaic performance QDSSCs, especially short-circuit current density (Jsc), experienced an obvious change when are employed. with average size distribution ~500 presented a better than QDSSCs other HS....
CdSe clusters react with liquid Bi- nanocatalysts to form one-dimensional nanowires in solution. The use of cluster precursors as compared molecular leads a high local concentration, which favors the growth thin diameters and narrow diameter distribution.
Size controllable TiO2 hollow microspheres (HMS) were synthesized by a carbonaceous spheres (CS) template method. Based on HMS, the ZnS/CdS quantum dots (QDs) loaded to form ZnS/CdS@TiO2 HMS photoanode for sensitized solar cell (QDSSC). The size effects of photovoltaic performance investigated, and showed that with sizes ~560 nm produced best short-circuit current density (Jsc) 8.02 mA cm-2 highest power conversion efficiency (PCE) 1.83%, showing better than any other QDSSCs based ~330 nm,...
