Abstract The topic chapter provides a systematic study on plasmonic effects in
organic solar cells (OSCs). We first introduce the concepts, significance, and
recent progress of OSCs incorporating plasmonic nanostructures. On the basis of
unique features of OSCs, we exploit versatile resonance mechanisms acting on the
absorption enhancement of OSCs; for example, Fabry-Pérot mode, quasi-guided
mode, and plasmonic mode. Next, we present rigorous theoretical models to
characterize optical properties of OSCs. The key physical quantities, as well as the
pros and cons of different models, are described in detail. After that, we show
some theoretical results to unveil the fundamental and device physics of plasmonic
effects in typical OSC structures. Finally, we conclude the chapter and identify
future opportunities in this field.
