Abstract :
We designed an organic photovoltaic (PV) device with a gold (Au) grating top and a silver (Ag) bottom electrode. The Au grating will induce laterally propagating surface plasmon-polaritons (SPPs) along the interface between the PV active layer and the bottom Ag electrode. The SPPs enhance the light absorption length without increasing the PV active layer thickness.
