A method of fabricating an organic semiconductor device, comprising:
- processing a single component conjugated polymer, in a presence of a processing additive and onto a substrate, wherein:
- the single component conjugated polymer processed onto the substrate is fabricated into an active region of an organic semiconductor device on the substrate;
- the single component conjugated polymer comprises both donor and acceptor repeating units;
- and
- a carrier mobility in the active region is increased as compared to a carrier mobility in a control active region of a control organic semiconductor device where the single component conjugated polymer is processed without the processing additive.
An organic semiconductor device, comprising:
- an active region including a single component conjugated polymer processed using a processing additive and wherein the single component conjugated polymer comprises a regioregular polymer comprising:
- both donor and acceptor repeating units;
- a main chain section having a repeat unit that comprises a pyridine, and
- a carrier mobility in the active region increased as compared to a carrier mobility in a control active region of a control organic semiconductor device where the single component conjugated polymer is processed without the processing additive.
An organic semiconductor device, comprising:
- an active region including a single component conjugated polymer processed using a processing additive, wherein the single component conjugated polymer comprises a regioregular polymer comprising:
- both donor and acceptor repeating units, and
- a main chain section having a repeat unit that comprises a pyridine, wherein the repeat unit further comprises a dithiophene.
