The morphology development of polymer-based blends, such as those used in organic photovoltaic (OPV) systems, typically arrests in a state away from equilibrium-how far from equilibrium this is will depend on the materials chemistry and the selected

Origin of fullerene-induced vitrification of fullerene:donor polymer photovoltaic blends and its impact on solar cell performance

Autor: John C. de Mello, Paul Westacott, Neil D. Treat, Michael L. Chabinyc, A. B. Sieval, Natalie Stingelin, James H. Bannock, Jasper J. Michels, Jaime Martín

Publikováno v: Journal of Materials Chemistry A

Organic solar cell blends comprised of an electron donating polymer and electron accepting fullerene typically form upon solution casting a thin-film structure made up of a complex mixture of phases. These phases can vary greatly in: composition, ord

Publikováno v: Physical Review Letters. 121

We introduce a new application of solid state NMR measurements towards characterizing the donor-acceptor interfaces within bulk heterojunction (BHJ) films. Rotational echo double resonance (REDOR) is used to measure dipolar couplings between C-13 nuc

[70]PCBM and Incompletely Separated Grades of Methanofullerenes Produce Bulk Heterojunctions with Increased Robustness for Ultra-Flexible and Stretchable Electronics

Autor: Darren J. Lipomi, Alexander B. Sieval, Suchol Savagatrup, Jan C. Hummelen, Adam D. Printz, Daniel Rodriquez

Publikováno v: Chemistry of Materials, 27(11), 3902-3911. AMER CHEMICAL SOC

An organic solar cell based on a bulk heterojunction (BHJ) of a polymer and a methanofullerene ([60]PCBM or [70]PCBM) exhibits a complex morphology that controls both its photovoltaic and mechanical compliance (robustness, flexibility, and stretchabi

Chemical Communications, 51(38), 8126-8129. Royal Society of Chemistry

A series of new, easily synthesized C-60-fullerene derivatives is introduced that allow for optimization of the interactions between rr-P3HT and the fullerene by systematic variation of the size of the ester group. Two compounds gave overall cell eff

Publikováno v: Chemical Communications, 53(5), 975-978. ROYAL SOC CHEMISTRY

The as-produced isomer mixture of the organic photovoltaic device acceptor material bis-[60] PCBM has been purified into its constituents by peak-recycling HPLC, and those individual isomers were characterised by UV-Vis absorption spectroscopy and cy

Exciton Quenching Close to Polymer−Vacuum Interface of Spin-Coated Films of Poly(p-phenylenevinylene) Derivative

Autor: Oleksandr V. Mikhnenko, Fabrizio Cordella, Alexander B. Sieval, Maria Antonietta Loi, Paul W. M. Blom, Jan C. Hummelen

Publikováno v: Journal of Physical Chemistry B, 113(27), 9104-9109. AMER CHEMICAL SOC

Polymer-fullerene bilayer heterostructures are suited to study excitonic processes in conjugated polymers. Excitons are efficiently quenched at the polymer-fullerene interface, whereas the polymer-vacuum interface is often considered as an exciton-re

Publikováno v: Journal of Physical Chemistry B, 112(37), 11601-11604. AMER CHEMICAL SOC

The temperature dependence of the exciton dynamics in a conjugated polymer is studied using time-resolved spectroscopy. Photoluminescence decays were measured in heterostructured samples containing a sharp polymer-fullerene interface, which acts as a
