When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Counterion‐Controlled Photocatalytic Doping of Organic Semiconductors

open access: yesAdvanced Materials, EarlyView.
Counterion size is shown to actively control photocatalytic doping in organic semiconductors. Small anions suppress aggregation of acridinium photocatalysts, enhance electron transfer, and dramatically increase doping efficiency. This simple strategy enables conductivities up to 2000 S cm−1 in benchmark polymers, revealing counterions as a powerful yet

Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

open access: yesAdvanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...
