Enhanced carrier mobility and photon-harvesting property by introducing Ag nano-particles in Flexible PSCs |
| 초록 |
In this study, flexible polymer solar cells (FPSCs) doped with Ag nanoparticles (Ag NPs) were successfully fabricated to maximize the photon-harvesting properties on the photoactive layer. In addition, a conductivity-enhanced hybrid buffer layer was introduced to improve the photon absorption properties and effectively separate the generated charges by adding Ag NPs and aprotic polar solvent to the PH 500 as a buffer layer. The FPSC performance was optimized with a 88% improvement over the conventional PSCs The internal resistance was decreased due to the increased photocurrent caused by the localized surface plasmon resonance (LSPR) effect of the Ag NPs in the photoactive layer and by the improvement of carrier mobility induced by aprotic polar solvent doping of the buffer layer. As a result, the series resistance (Rs) deceased from 42.3 to 19.7 Ωcm2 while the shunt resistance (Rsh) increased from 339 to 487 Ωcm2. |
