“…12 Moreover, also in a diode made from a crystalline blend of P3HT and highdensity polyethylene ambipolar transport has been observed recently. 13 All other reported experiments on electron-only ͑EO͒ diodes of conjugated polymers exhibit strongly reduced current that mask the transport of free electrons. For the case that E tc = 0, as show in Fig.…”

“…[34][35][36][37] Here, we set out to investigate if n-type organic composites could be obtained by mixing a p-type conjugated polymer with nitrogen doped n-type CNTs. We chose poly(3-hexylthiophene) (P3HT) since it can show ambipolar transport [ 38 ] and can wrap around CNTs. [ 36 ] A moderate regioregularity of RR > 90% was selected in order to not limit the solubility of the polymer.…”

“…3,4 Blending of organic materials is an attractive approach to optimize and tune the properties of the materials for device applications. [5][6][7][8][9][10] Additionally, blending can result in new phenomena and properties as a result of intermolecular interactions, selforganization ͑or its frustration͒, and confinement effects. 7,11 In organic photovoltaic devices it is especially critical to use a blend rather than a neat material.…”

Charge transport in disordered organic blends is studied theoretically by numerically solving the Pauli master equation. The influence of morphology, disorder, electric field, and charge carrier concentration on blend mobility is assessed. Important differences between neat materials and blends are found. The dependence of mobility on charge carrier concentration is more pronounced in blends and it is influenced by the electric field strength. At low charge carrier densities, blend mobility is found to decrease with increasing field. Additionally, the impact of the volume ratio of the constituent materials and their domain size on the mobility is presented. Especially for strongly disordered materials charge transport is favored by relatively large domains. To compare these theoretical findings with existing experimental mobility data, the current density in a space-charge-limited device is computed. The author finds that, for the parameters and morphologies studied, the apparent mobility in such a device decreases with increasing bias voltage.
