Modern optoelectronic devices, such as light-emitting diodes, field-effect transistors and
organic solar cells require well controlled motion of charges for their efficient operation. The …

To improve the photoelectrochemical activity of TiO 2 for hydrogen production through water
splitting, the band edges of TiO 2 should be tailored to match with visible light absorption …

It has recently been demonstrated that the hopping mobility in semiconducting organic
materials depends on the charge-carrier concentration. We have analyzed this effect within …

The separation of photogenerated polaron pairs in organic bulk heterojunction solar cells is
the intermediate but crucial step between exciton dissociation and charge transport to the …

Herein, we focus on the principles of photoconduction in random semiconductors—the key
processes being optical generation of charge carriers and their subsequent transport. This is …

Carrier thermoelectric-transport theory has recently become of growing interest and
numerous thermoelectric-transport models have been proposed for organic semiconductors …

An “organic photoconductor”(OPC) or “organic photoreceptor” is the photoelectric element
that is at the heart of the electrophotographic (EP) printing process. The terms organic …

Low-frequency current fluctuations are investigated over a bias range covering Ohmic, trap-
filling, and space-charge-limited current regimes in polycrystalline polyacenes. The relative …

Detailed studies of hole mobility in the electroluminescent conjugated polymer poly (9, 9′-
dioctylfluorene) by the time-of-flight technique are reported. The hole mobility is studied in a …
