The use of Ti meshes with self‐organized TiO₂ nanotubes as photoanodes of all‐Ti dye‐sensitized solar cells

Abstract

This paper reports a simple and facile method for directly growing self-organized TiO 2 nanotubular arrays around the whole Ti mesh by electrochemical anodization in organic electrolytes and their application in all-Ti dye-sensitized solar cells (DSSCs). Compared with the traditional fluorine-doped tin oxide (FTO)-based DSSC and the backside illuminated DSSC, this type of DSSC showed advantages such as low resistance, cheap fabrication cost and enhanced sunlight utilization. Different thicknesses of nanotubular array layers were investigated to find their influence on the photovoltaic parameters of the cell. We also considered three types of meshes as the substrates of anodes and found that the cell with 6 openings/mm 2 exhibited the highest conversion efficiency of 5.3%. The area of the cell had only a little impact on the photovoltaic performances.

Transparent Conductive Oxide Less Flexible Dye-sensitized Solar Cells with Flat and Cylinder Shapes

“…We focused on structures and fabrication process of transparent conductive oxide less DSCs (TCO-less DSCs), where porous metal electrodes are fabricated at the back side of titania/dye layers as back-contact structures as shown in Fig.1. [3][4][5][6][7] We have already reported flat type, fiber type, and cylinder type dye sensitized solar cells [8][9][10][11][12]. In this report, how to optimize the structure for each cell is discussed.…”

“…3 In addition, it is not easy to fabricate the TCO layer inside of a curved glass, which limits the shape of the solar cells. [8][9][10][11][12] Fan et al have also reported the DSC based on Ti mesh electrode with 1.49% efficiency. [4][5][6][7] Figure 1 shows a representative TCO-less DSC structure.…”
