  • Singlet fission converts single singlet excitons into pairs of triplet excitons, and it has been proposed to give additional photocurrent to solar cells. Ehrleret al. use lead selenide nanocrystals of varying sizes to measure the triplet energy in pentacene photovoltaic cells, and achieve efficiencies approaching 5%.

  • One-dimensional nanostructures have been shown to increase multiple-exciton generation, offering a pathway to breaking the Shockley–Queisser limit. Here, Davis et al. have fabricated working photovoltaic devices based on high-quality PbSe nanorods and a maximum external quantum efficiency of 122 % was demonstrated.

  • The integration of nano-molecules into microelectronic circuitry is challenging. Here, the authors provide a scalable method for contacting a self-assembled monolayer of nanoparticles with a single layer of graphene that produces single-electron effects, in the form of a Coulomb staircase, with a yield of at least 70%.
