“…Just after UV/ozone treatment, work function increased up to 5.22 eV. This value is very close to previously reported values, 5.25 « 0.1 eV, 9) 5.15 eV, 10) 5.2 eV. 11) Sugiyama et al reported that three factors, i.e.,: (i) C-containing contaminants, (ii) the O/In ratio, and (iii) the In/Sn ratio on the ITO surface, affect the work function in the order: (ii) > (i) > (iii), and (i) is the major reason of the increase in the work function due to the UV/ozone or O 2 plasma treatments.…”

In situ measurements of work function of indium tin oxide after UV/ozone treatment were carried out using a photoemission yield spectrometer with an open counter. Although the work function increased just after UV/ozone treatment, it decreased as time passed and finally returned to the initial value. The continuous change in work function with exposure to air was observed under dry atmosphere and at various temperatures. The returning process at higher temperature proceeded faster than at lower temperature. By contrast, humidity has no influence on the work function recovery. The exponential decay of work function was consistent with the first-order reaction rate equation. The rate constant obeyed Arrhenius' equation, and the activation energy was estimated to be 22 kJ/mol.

In this study, the different TiO 2 layer thicknesses and electrolyte thicknesses were investigated, which were applied in the dye-sensitized solar cells (DSSC). The amount of dye adsorption was decided by thickness of TiO 2 layer, the appropriated TiO 2 thickness could increase the short-circuit current density of DSSC and decreased the resistance of TiO 2 layer, effectively. The oxidationreduction reaction of inner electrochemical of DSSC was decided by thickness of electrolyte. The appropriate electrolyte thickness could increase the redox rate of DSSC and decreased the distance of electron transmission, effectively.

Flexible dye-sensitised solar cells (FDSSCs) which have different quantities of arrayed titanium dioxide (TiO 2 ) working electrode for parallel modules are introduced. FDSSCs are usually fabricated as a module type instead of single cell to enhance conversion efficiency and characteristic parameters. The general FDSSCs modules are designed as parallel strip-shaped and as parallel interconnection types, and there are some advantages such as easy fabrication, low cost and simple structure. In this reported study, the active areas of FDSSCs are the same (0.48 cm 2 ), and they have different quantities of TiO 2 thin films. The single strip-shaped TiO 2 working electrode has a larger internal resistance than more quantities of TiO 2 thin films. Therefore, and they have fabricating the different quantities of arrayed flexible TiO 2 working electrodes is the better method to solve the problem, higher internal resistance than single TiO 2 thin film. As a result, the FDSSC, which has the triple stripshaped TiO 2 working electrode, has a higher conversion efficiency (0.25%) than other different quantities of TiO 2 thin films.
