Parameters obtained from the electric impedance spectra (EIS) of the solid-state DSSCs based on FTO coated glass slides and screen printed polyimide glass fibre textile. (R equals R1 plus R4.).
| Device | R* (kΩ/cm2) | R2 (kΩ/cm2) | R3 (Ω/cm2) | CPE (F) | Bode peak (Hz) | Electron lifetime Tn (ms) |
|---|---|---|---|---|---|---|
| FTO glass | 0.36 | 0.72 | 165 | 3.3 × 10−5 | 66.02 | 2.41 |
| Liquid polyimide coated glass | 0.54 | 120 | — | 1.34 × 10−9 | 2034 | 7.82 × 10−2 |
*R = R1 + R4.
