Abstract
Efficient creation of excitons in organic solar cells requires a large optical path of light through the active material. However, organic cells feature very low charge mobility requiring very thin active layers around one hundred nanometers. To increase light matter-interactions in thin polymers, metallic particles or nanostructuration have been proposed to scatter impinging light into the polymer [1-2] but their efficiency is often counter-balanced by the intrinsic losses of metals that spoil the creation of electric charges.
