Environment Sensitive Localized Surface Plasmon Resonance of Silver Nanodot Arrays Incorporated Polymer Solar Cells |
| 초록 |
The application of localized surface plasmon resonance (LSPR) phenomena is one way among the most effective strategies to enhance the performance of polymer solar cells (PSCs). Uniform 10 nm Ag nano-arrays (Ag NAs) were synthesized via block copolymer micelle lithography (BCML) and utilized in inverted structure PSCs. The Ag NAs were incorporated into various electron transport layers (ETLs) with different refractive indices. The resonant wavelength of Ag NAs showed a significant red-shift as the refractive index of the surrounding medium increased, which was consistent with theoretical calculations of the plasmonic materials, taking damping constants, non-local response and coupling effects into account. When incorporated into PSC devices, power conversion efficiencies (PCEs) of up to 8.51% were realized using Ag NPs embedded in TiO2 ETLs, corresponding to a 12.5% enhancement in JSC compared to 7.55% PCE observed in control devices without Ag NAs. |
