Preparation of Flexible Dye-sensitized Solar Cells Based on Hierarchical Structure ZnO Nanosheets

ZnO nanotube based dye-sensitized solar cells.

We introduce high surface area ZnO nanotube photoanodes templated by anodic aluminum oxide for use in dye-sensitized solar cells (DSSCs). Atomic layer deposition is utilized to coat pores conformally, providing a direct path for charge collection over tens of micrometers thickness. Compared to similar ZnO-based devices, ZnO nanotube cells show exceptional photovoltage and fill factors, in addit...

ZnO Nanostructures for Dye-Sensitized Solar Cells

This Review focuses on recent developments in the use of ZnO nanostructures for dye-sensitized solar cell (DSC) applications. It is shown that carefully designed and fabricated nanostructured ZnO films are advantageous for use as a DSC photoelectrode as they offer larger surface areas than bulk film material, direct electron pathways, or effective light-scattering centers, and, when combined wi...

Aerogel Templated ZnO Dye-Sensitized Solar Cells

Dye-sensitized solar cells (DSSCs) based on nanocrystalline TiO2 have exhibited solar energy-conversion efficiencies of over 10% and remain one of the most promising candidates for cost-effective solar energy conversion devices. The most efficient DSSCs reported to date utilize a high surface area photoanode, which allows for good light harvesting with a moderate extinction dye, in contact with...

Fabrication of ZnO Based Dye Sensitized Solar Cells

Influence of nanostructured TiO2 film thickness on photoelectrode structure and performance of flexible Dye- Sensitized Solar Cells

A  commercial  Ti-Nanoxide  was  deposited  on  In-doped  SnO2 (ITO) polymer  substrates by  tape casting  technique with different thicknesses  (7,  14  and  36μm)  to  be  used  as  photoelectrode  in flexible  dye-sensitized  solar  cells  (DSSCs).  Ruthenium  dye  was adsorbed on each TiO2 film for 24 h. The resulting photoelectrodes were used to form flexible DSSCs in combination with...
