The exciton root-mean-square displacement D in regioregular poly 3-hexylthiophene P3HT deposited onto meso-tetrakis n-methyl-4-pyridyl porphyrin tetrachloride H2TMPyP has been determined from the photovoltaic response of a device based on these materials in a bilayer configuration. Excitons formed on illumination that reach the interface between H2TMPyP and P3HT can undergo interfacial charge s...

The influence of arrangement of poly(3-hexylthiophene) (P3HT) chains embedded into poly(methyl methacrylate) (PMMA) matrix on photophysical properties, such as electronic absorption spectrum, band gap, and photoluminescence quantum yield, of the formed P3HT aggregates have been studied. It has been found that variation of P3HT fraction in PMMA matrix from 25 to 2 wt% is accompanied with the inc...

Organic/inorganic hybrid solar cells have great potentials to revolutionize solar cells, but their use has been limited by inefficient electron/hole transfer due to the presence of long aliphatic ligands and unsatisfying continuous interpenetrating networks. To solve this problem, herein, we have developed a one-pot route for in situ synthesis of poly(3-hexylthiophene) (P3HT)-capped CdSe supers...

Nanoribbon-shaped nanocomposites composed of conjugated polymer poly(3-hexylthiophene) (P3HT) nanoribbons and plasmonic gold nanorods (AuNRs) were crafted by a co-assembly of thiol-terminated P3HT (P3HT-SH) nanofibers with dodecanethiol-coated AuNRs (AuNRs-DDT). First, P3HT-SH nanofibers were formed due to interchain π-π stacking. Upon the addition of AuNRs-DDT, P3HT-SH nanofibers were transfor...

Poly(3-hexylthiophene) (P3HT) degrades in organic solvents containing dissolved molecular oxygen when irradiated with ultraviolet light. Hence, it is important to develop strategies that can enhance the photostability of P3HT and enhance the device performance. In this work, we report that preparing composites of P3HT with appropriate amounts of multiwalled carbon nanotube (MWCNT) results in su...

Nanoscale morphology is of significance to the electronic properties of semiconducting polymers. Solution-processed poly-3-hexylthiophene (P3HT) has been demonstrated as a promising active-layer material in organic thin film transistors (OTFTs) and solar cells. Controlling the crystallinity of P3HT chains is critical for gaining high-performance devices. Here we demonstrated the immediate cryst...

Abstract The first comprehensive spectroelectrochemical account of the behaviour of regioregular (RR-P3HT) and statistical (ST-P3HT) poly(3-hexylthiophenes) in solution is presented, in contrast to the many reports dealing with P3HT films merely deposited from solution. The conducted experiments revealed that the two types of P3HTs behave in sharply different ways upon the application of electr...

Poly(3-hexylthiophene) (P3HT) is one of the most extensively investigated conjugated polymers and has been employed as the active material in many devices including field-effect transistors, organic photovoltaics and sensors. As a result, methods to further tune the properties of P3HT are desirable for specific applications. Herein, we report a facile postpolymerization modification strategy to...

Composites prepared by grafting poly(3-hexylthiophene) (P3HT) onto the surfaces of reduced graphene oxide (RGO) (RGO-g-P3HT) exhibit an enhanced photothermal effect due to photoinduced energy transfer from P3HT to RGO. A remote photo-controlled electrical switch was prepared using RGO-g-P3HT as a photothermal layer.

We have designed highly efficient ternary blend solar cells based on a wide-bandgap crystalline polymer, poly(3-hexylthiophene) (P3HT), and a low-bandgap polymer, poly[(4,4'-bis(2-ethylhexyl)dithieno[3,2-b:2'3'-d]silole)-2,6-diyl-alt-(2,1,3-benzothiadiazole)-4,7-diyl] (PSBTBT), and a fullerene derivative (PCBM). By using highly crystalline P3HT, high fill factors were obtained even for ternary ...
