The high trap density (generally 1016–1018 cm− 3) in organic solar cells (OSCs) brings
about the localization of charge carriers and reduced charge carrier lifetime, mainly due to …

Organic semiconductors (OSCs), ie, π-conjugated small molecules and polymers, exhibit

Charge carrier transport in organic semiconductor devices is thermally activated with
characteristic activation energies in the range of 0.2–0.6 eV, leading to strongly temperature …

In this study, quantum dot light-emitting diodes based on non-toxic silicon quantum dots
functionalized with hexyl and dodecyl organic ligands showed a negative capacitance effect …

Organic nonfullerene acceptors (NFA) have received tremendous research interests due to
the efficient interfacial charge transfer (CT) when they combine with polymeric donors. It is of …

We develop an analytical model for the photocurrent of organic solar cells based on carrier
drift and including second-order charge recombination, in which the figure of merit θ o …

We demonstrate the influence of a light-soaking treatment on current-voltage characteristics,
external quantum efficiency and dielectric response of an encapsulated P3HT: PCBM bulk …

We use frequency-modulated electrostatic force microscopy to track changes in cantilever
quality factor (Q) as a function of photochemical damage in a model organic photovoltaic …
