Summary of charge density, carrier lifetime, and recombination current for each HTM based PSC.
| HTM | Q (nC/cm2) | τ (μs) | OF | Jrec (mA/cm2) | JSC (mA/cm2) |
|---|---|---|---|---|---|
| Spiro-OMeTAD | 157 | 0.98 | 6.4 | 25.0 | 24.3 |
| PTB7 | 115 | 0.92 | 4.7 | 26.6 | 19.6 |
| P3HT | 170 | 2.40 | 3.8 | 18.6 | 18.8 |
| PCPDTBT | 85 | 2.20 | 3.3 | 11.7 | 14.6 |
Specifically, Q is calculated with the PIDC method, τ is measured with PI-TPV at 1 sun background LI, Jrec is calculated from Eq. 4 and JSC is the experimental value obtained from J-V graphs in reverse sweep.
