Abstract

We conduct a review of the recent progress of utilizing amorphous and semicrystalline polymer additives with varying molecular weight to manipulate the crystallization, morphology, and charge transport of solution-processable organic semiconductors.

Highlights

  • Introduction and background1.1 Recent progress of flexible electronics In recent years, research in flexible electronics has unveiled rapid progress [1,2,3,4,5,6,7,8,9,10,11]

  • These research endeavors have opened up vast opportunities for the organic semiconductors to be applied in high performance organic electronic devices such as organic thin film transistors [3235], organic gas sensors [36,37,38], photovoltaic devices [39,40,41] and logic circuits [42,43,44]

  • This study indicated that tuning the polymer viscosity by employing the polymer additives with different molecular weight can be a pathway to regulate the thin film morphology of organic semiconductors
