We study surface photovoltage decays on sub-millisecond time scales in organic solar cells
using intensity-modulated scanning Kelvin probe microscopy (SKPM). Using …

We report computer simulations of an excess electron in various structural motifs of
polyethylene at room temperature, including lamellar and interfacial regions between …

We investigated solution-grown single crystals of multidimensional 2D–3D hybrid lead
bromide perovskites using spatially resolved photocurrent and photoluminescence …

This work investigates the energy and spatial properties of excess electrons in polyethylene
in bulk phases and, for the first time, at amorphous vacuum interfaces using a …

We demonstrate nanoscale imaging of charge transfer state photoexcitations in
polymer/fullerene bulk heterojunction solar cells using time-resolved electrostatic force …

We have used ab initio molecular dynamics and density-functional theory (DFT) calculations
at the B3LYP/6-31G** level of theory to evaluate the energy and localisation of excess …

The field of organic solar cells (OSCs) has developed rapidly over the last two decades, and
polymer solar cells with power conversion efficiencies of 13.1% have been reported. The …

The advent of optically functional materials with low-intensive processing methods is
accompanied by a growing need for high resolution imaging to probe the inherent …

We directly observed charge separation and a space‐charge region in an organic single‐
crystal p–n heterojunction nanowire, by means of scanning photocurrent microscopy. The …

One‐dimensional scanning optical beam‐induced current (OBIC) measurements have been
carried out on polymer bulk heterojunction (BHJ) photovoltaic cells with a planar, or lateral …
