Photovoltaic characteristics of wet-corroded Ti foil dye-sensitized solar cells (DSSCs) at 50 °C for different corrosion time periods. IE: ion exchange; FF: fill factor; Voc: open-circuit voltage; η: power conversion efficiency; Jsc: photocurrent density.
| Wet Corrosion Time (h) | Voc (V) | Jsc (mA/cm2) | FF (%) | η (%) |
|---|---|---|---|---|
| 6 | 0.63 | 0.60 | 72.0 | 0.27 |
| 12 | 0.64 | 0.92 | 71.7 | 0.42 |
| 24 | 0.67 | 1.76 | 68.3 | 0.80 |
| 48 | 0.69 | 2.08 | 71.5 | 1.03 |
| 48 (IE) | 0.69 | 2.28 | 70.1 | 1.11 |
