제목 Innovative Design of Two-Dimensional Plasmonic Interlayers for High-Efficient Organic Photovoltaic Cells
초록 Plasmonic nanodots (PNDs) 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, a viable and promising optical engineering technique which enables the development of high-performance OPV was demonstrated. We elaborately control the size as well as the periodicity of the PNDs via laser interference lithography which can induce the spectral overlap between the absorption of the organic semiconductors and the plasmon resonance of PNDs. As a result, PNDs arrays led to a remarkable enhancement in power conversion efficiency up to 10.61 % from 7.52 % compared with the control device. Near field enhancement and light scattering effect are responsible for the significantly improved device performance. Finite difference time domain simulation and external quantum efficiency results support the enhanced performance.
