Plasmonic Nanodot Array via Laser Interference Lithography for ＞ 10 % Efficiency Organic Photovoltaic Cells |
| 초록 |
Metallic nanodots (MNDs) have been widely utilized for the development of high-performance organic photovoltaic (OPV) cells by amplifying light absorption at the active layer. In this study, promising optical engineering which enables the development of high-performance OPV was demonstrated. We elaborately control the size and periodicity of the MND arrays via laser interference lithography. The MND arrays can induce the spectral overlap between the absorption range of the organic semiconductors and the plasmon resonance of MNDs. As a results, MND arrays led to a remarkable enhancement in power conversion efficiency up to 10.55 % from 7.2 % compared with control device. Near field enhancement and light scattering effect are responsible for the significantly improved device performance. |
