| Popis: | 102 In this thesis, the dye-sensitized solar cell (DSSC) was fabricated on flexible indium tin oxide/polyethylene terephthalate (ITO/PET), and investigated effect of different designed and arrayed. Firstly, flexible arrayed dye-sensitized solar cell was fabricated as mutual electrolyte structure. Part of conductive thin films was etched that opportunity for electrolyte to contact ITO thin films was reduced, and interface impedance was reduced. According to experimental results, when distance between the electrodes was 1 mm obtained optimal, which the open circuit voltage (VOC) was 0.81 V, the short circuit current density (JSC) was 1.70 mA/cm2, and the photovoltaic conversion efficiency was 0.37 %. Transmittance of transparent conductive substrate via etching was increased, which was found in previous experiments. So that designed different distances electrodes and investigated relation of transmittance. Optimal distance of comb-electrodes was 1 mm, which the open circuit voltage was 0.77 V, the short circuit current density was 1.20 mA/cm2, the fill factor (F. F.) was 46 % and the photovoltaic conversion efficiency was 0.43 %, and the transmittance was improved about 15 %. The most significant feature of the flexible substrate is bendable, but its packaging characteristic was poor. In further, the dye-sensitized solar cell produced leaking electrolyte, so the characteristic of dye-sensitized solar cell was investigated with different compressions for packaging. The optimal compression of packaging was 4 kgf/cm, which the lowest loss weight ratio (LWR) was 0.46%. |
