TL;DR: The synthesis and polymerization of a novel thieno[3,2-b]thiophene-diketopyrrolopyrrole-based monomer is reported, which has a maximum hole mobility of 1.95 cm(2) V(-1) s(-1), which is the highest mobility from a polymer-based OFET reported to date.

TL;DR: In this article, the authors investigate the reasons for the discrepancies by determining both ideality factors differentially as a function of voltage and by comparing them with simulations and find that both the dark and light ideality factor are sensitive to bulk recombination mechanisms at the internal donor:acceptor interface, as is often assumed in the literature.

TL;DR: In this article, a series of thiazolo-thiazole donor polymers that differ in their side groups (and bridging atoms) are blended with two acceptor fullerenes, phenyl-C71-butyric acid methyl ester (PC71BM) and a fullerene indene-C60 bisadduct (ICBA).

TL;DR: It is shown that lower charge separation in the fluorinated system is associated with the formation of bound electron-hole pairs, which undergo spin-state mixing on the nanosecond timescale and subsequent geminate recombination to triplet excitons, and can be dissociated by electric fields.

TL;DR: In this article, the synthesis and characterization of four diketopyrrolopyrrole containing conjugated polymers for use in organic photovoltaics is presented.
