Semiconducting:insulating polymer blends for optoelectronic applications—a review of recent advances
TL;DR: In this article, the authors discuss the working principle of semiconductor:insulator blends, examining the different approaches that have recently been reported in literature, and illustrate how organic field effect transistors (OFET) and organic solar cells (OPV) can be fabricated with such systems without detrimental effects on the resulting device characteristics even at high contents of the insulator.
Journal ArticleDOI
Engineering semiconducting polymers for efficient charge transport
TL;DR: In this paper, the authors propose that disorder is an inextricable aspect of polymer morphology which need not be highly detrimental to charge transport if it is embraced and planned for.
