Organic Solar Cells: High Efficiency Organic Solar Cells Achieved by the Simultaneous Plasmon‐Optical and Plasmon‐Electrical Effects from Plasmonic Asymmetric Modes of Gold Nanostars (Small 37/2016)

Plasmonic organic solar cells with an efficiency of 10.5% are achieved by simultaneous plasmon-optical and plasmon-electrical effects from gold nanostars, as presented by W. C. H. Choy and co-workers on page 5200. Due to the excited plasmonic asymmetric modes, their optical effects induce a broadband absorption enhancement. Meanwhile, their electrical effects of offering better balanced carrier transport path length and lower carrier transport resistance facilitate a better carrier collection.
