The mean photocurrent and efficiency enhancement of three CIGS solar cells upon the incorporation of various concentrations of Au and Ag nanoparticles.
| Enhancement Factor | Nanoparticle Concentrations | Annealed Samples | 1% | 5% | 10% | 20% |
|---|---|---|---|---|---|---|
| Au | Jsc ((Jsc(Au) − Jsc/Jsc) | < 0.1% | 5.9% | 3.7% | −2.3% | −3.1% |
| Eff((Eff(Au) − Eff)/Eff) | < 0.1% | 1.2% | 1.1% | −0.3% | −1% | |
| Excluded thermal annealing effect, Eff | ~1.2% | ~1.1% | ~−0.3% | ~−1% | ||
| Ag | Jsc ((Jsc(Ag) − Jsc)/Jsc) | < 0.1% | 2.3% | 1.9% | −3.3% | −4.3% |
| Eff((Eff(Ag) − Eff)/Eff) | < 0.1% | 0.5% | 1.4% | −0.1% | −2.1% | |
| Excluded thermal annealing effect, Eff | ~0.5% | ~1.4% | ~−0.1% | ~−2.1% | ||
