Solar Cells: Emissive Nanoclusters Based on Subnanometer‐Sized Au38 Cores for Boosting the Performance of Inverted Organic Photovoltaic Cells (Adv. Energy Mater. 13/2015)

As reported by Dong Chan Lim, Young Dok Kim, Shinuk Cho, and co-workers in article number 1500393, the efficiency of inverted bulk heterojunction solar cells is successfully enhanced by the incorporation of dodecanethiol monolayer-protected Au nanoclusters (Au:SR) based on sub-nanometer-sized Au38 cores. Solar cells with the Au:SR cluster exhibit 20% increased efficiency as a result of effective energy transfer based on the protoplasmonic fluorescence of Au:SR.
