Abstract

We present plasmonics-enhanced organic solar cells (OSCs) containing nanostructures of plasmonic metals in the hole transport layer extending to the active layer of the solar cell. Finite-difference time-domain (FDTD) modeling was employed to simulate the interaction of incident light with the plasmonic nanostructures, leading to a broadband absorption enhancement in the OSCs. We studied the effect of employing nanostructures of different sizes and materials on the absorption enhancement in the OSCs. In some OSCs, we demonstrate 32% increase in the short circuit current density due to the presence of plasmonic nanostructures.
