TL;DR: In this article, the charge transfer doping efficiencies of π-stacked poly(3-hexylthiophene) (P3HT) aggregate nanofibers are studied using spectroscopic and electron microscopy probes.
Resonance Raman Spectroscopic- and Photocurrent Imaging of Polythiophene/Fullerene Solar Cells
TL;DR: In this article, the morphology-dependent polymer aggregation state is spatially mapped to local photocurrent generation efficiency in poly-(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) blend thin film photovoltaic devices.

High intrachain order promotes triplet formation from recombination of long-lived polarons in poly(3-hexylthiophene) J-aggregate nanofibers.
TL;DR: The results demonstrate the promise of self-assembly strategies to control intrachain ordering within multichromophoric polymeric aggregate assemblies to tune exciton coupling and interconversion processes between different spin states.

Spatially Resolving Ordered and Disordered Conformers and Photocurrent Generation in Intercalated Conjugated Polymer/Fullerene Blend Solar Cells
TL;DR: It is shown that ordered PBTTT chains are most concentrated in PCBM-rich bimolecular crystals and corresponding intensity modulated photocurrent spectroscopy and imaging measurements show increased nongeminate charge recombination at the boundaries of ordered/disordered regions.

Interchain Charge-Transfer States Mediate Triplet Formation in Purified Conjugated Polymer Aggregates
TL;DR: In this article, the effect of structural ordering factors on triplet formation in self-assembled aggregate π-stacked chains of poly(3-hexylthiophene) (P3HT) using single-molecule time-resolved intensity modulation and electric-field-dependent photoluminescence (PL) spectroscopy was studied.
