Broadband dye-sensitized upconversion of near-infrared light

Researchers demonstrate an approach for upconverting near-infrared light in solar cells using an organic dye as an antenna for nanoparticles. Increased absorptivity and overall broadening of the upconverter's absorption spectrum enhance the upconversion process by a factor of around 3,300.

N-type organic thermoelectrics: demonstration of ZT > 0.3

Achieved high thermoelectric figure of merit (ZT) in organic thermoelectric materials remains a challenge due to their low packing order and poor host/dopant miscibility. Here, the authors report side chain-engineered n-doped fullerene derivatives with record ZT >0.3 for organic thermoelectrics.

Large negative differential conductance in single-molecule break junctions

A large negative differential resistance is detected in a single-molecule break junction and theoretical models validate intrinsic resonant transport inside the molecule.

Thiol-free self-assembled oligoethylene glycols enable robust air-stable molecular electronics

Chemisorbed molecules combining glycol-ether moieties and fullerenes are shown to form uniform and air-stable self-assembled bilayers on coinage metals, and are amenable to versatile functionalization by in-place exchange of the top layer.

Perovskites under the Sun

Mixed-halide organic–inorganic hybrid perovskites are reported to display electron–hole diffusion lengths over 1 μm. This observation provides important insight into the charge-carrier dynamics of this class of semiconductors and increases the expectations for highly efficient and cheap solar cells.
