“…StS has been used both as counter electrode (CE) [4][5][6][7][8] and photoelectrode (PE) substrate. 7,[9][10][11][12][13] To gain flexible DSC, transparent polymer substrates are used with metal substrates. The preparation of efficient PEs with low temperature techniques required in the case of polymer substrate has proven out to be more difficult compared to that of CEs.…”

A new segmented cell design was applied to study the aging of dye solar cell with stainless steel (StS) photoelectrode substrate, in particular the role of electrolyte in the degradation. Photovoltaic showed changes in the recombination at the photoelectrode / electrolyte interface. With the segmented cell method, we confirmed that the electrolyte was not contaminated by the StS nor was it subject to other significant changes related to the rapid degradation.

“…The experiment indicated that a proper length of the nanotubular array layer is a key factor to achieve high conversion efficiency. We also considered different 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%, which showed superiority compared with the backside illuminated DSSC [10] and other metalsubstrate-based DSSC [9,[11][12][13]. The area of the cell had only a little impact on the photovoltaic parameters.…”

“…Consequently, it is an undisputable fact that the TCO glass is one of the expensive components of the DSSCs. In order to overcome these problems, one of the TCO substrates was replaced with a Ti metal plate because it has low resistivity, low production cost and high temperature sinterability compared with the TCO glass [9]. This half-metal DSSC was composed of a Ti plate coated with a TiO 2 porous layer, electrolyte and a Pt sputtered TCO substrate.…”

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.

“…Moreover, some investigations have also reported that the cost of the TCO glass suitable for DSSCs is estimated to be 16%-24% of the total cost of the solar cell, 7 which means that the TCO glass is one of the expensive components of the DSSCs. One promising solution is to replace the TCO glass of the counter electrode side with a metal substrate 8 on account of its low resistance, low cost and high temperature sinterability, especially with the view of large-scale industrialization of the DSSCs. Fang et al 9 used stainless steel as the counter electrode substrate to make the fill factor ͑FF͒ and conversion efficiency for large scale DSSCs improved by 20% because of the reduced internal resistance.…”

Lett. 99, 213302 (2011) Additional information on J. Appl. Phys. In this paper, we develop a new type of three-dimensional dye-sensitized solar cells ͑3D DSSCs͒ with double deck cylindrical Ti meshes as the substrates. One of the Ti meshes is anodized to in situ synthesize the self-organized TiO 2 nanotube layer as the photoanode materials. Another Ti mesh is platinized through electrodeposition as the counter electrode. The morphologies of the electrodes are characterized by scanning electron microscopy. We investigate the effect of the mesh number on the 3D DSSCs with the dye adsorption, cyclic voltammetry, and electrochemical impedance spectroscopy. The results show that with the increase in the mesh number, the dye-loadings on the photoanode and the active surface area of Pt on the counter electrode are increased, while the diffusion of the electrolyte becomes more difficult due to the reduced diameter of the openings in the mesh. It has also been demonstrated that the performance of this 3D DSSC is independent of the incident solar beam angle due to its axial symmetrical structure. In the I-V measurement, the 3D DSSC based on the 90-mesh photoanode and the 120-mesh counter electrode shows the highest conversion efficiency of 5.5% under standard AM 1.5 sunlight. The problems of electrical insulator layer are discussed and further investigation is expected.
