Validating the use of intrinsic markers in body feathers to identify inter-individual differences in non-breeding areas of northern fulmars.

Marine biology

Quinn LR, Meharg AA, van Franeker JA, Graham IM, Thompson PM.
PMID: 27065496
Mar Biol. 2016;163:64. doi: 10.1007/s00227-016-2822-1. Epub 2016 Feb 29.

Many wildlife studies use chemical analyses to explore spatio-temporal variation in diet, migratory patterns and contaminant exposure. Intrinsic markers are particularly valuable for studying non-breeding marine predators, when direct methods of investigation are rarely feasible. However, any inferences regarding...

The Importance of Moisture in Hybrid Lead Halide Perovskite Thin Film Fabrication.

ACS nano

Eperon GE, Habisreutinger SN, Leijtens T, Bruijnaers BJ, van Franeker JJ, deQuilettes DW, Pathak S, Sutton RJ, Grancini G, Ginger DS, Janssen RA, Petrozza A, Snaith HJ.

ACS Nano. 2015 Sep 22;9(9):9380-93. doi: 10.1021/acsnano.5b03626. Epub 2015 Aug 06.

Moisture, in the form of ambient humidity, has a significant impact on methylammonium lead halide perovskite films. In particular, due to the hygroscopic nature of the methylammonium component, moisture plays a significant role during film formation. This issue has...

Polymer Solar Cells: Solubility Controls Fiber Network Formation.

Journal of the American Chemical Society

van Franeker JJ, Heintges GH, Schaefer C, Portale G, Li W, Wienk MM, van der Schoot P, Janssen RA.

J Am Chem Soc. 2015 Sep 16;137(36):11783-94. doi: 10.1021/jacs.5b07228. Epub 2015 Sep 01.

The photoactive layer of polymer solar cells is commonly processed from a four-component solution, containing a semiconducting polymer and a fullerene derivative dissolved in a solvent-cosolvent mixture. The nanoscale dimensions of the polymer-fullerene morphology that is formed upon drying...

Toward Practical Useful Polymers for Highly Efficient Solar Cells via a Random Copolymer Approach.

Journal of the American Chemical Society

Duan C, Gao K, van Franeker JJ, Liu F, Wienk MM, Janssen RA.

J Am Chem Soc. 2016 Aug 31;138(34):10782-5. doi: 10.1021/jacs.6b06418. Epub 2016 Aug 16.

Using benzo[1,2-b:4,5-b']dithiophene and two matched 5,6-difluorobenzo[2,1,3]thiadiazole-based monomers, we demonstrate that random copolymerization of two electron deficient monomers, alternating with one electron rich monomer, forms a successful approach to synthesize state-of-the-art semiconducting copolymers for organic solar cells. Over a range...

Energy Level Tuning of Poly(phenylene-.

Dichotomous Role of Exciting the Donor or the Acceptor on Charge Generation in Organic Solar Cells.

Journal of the American Chemical Society

Hendriks KH, Wijpkema AS, van Franeker JJ, Wienk MM, Janssen RA.
PMID: 27452683
J Am Chem Soc. 2016 Aug 10;138(31):10026-31. doi: 10.1021/jacs.6b05868. Epub 2016 Aug 02.

In organic solar cells, photoexcitation of the donor or acceptor phase can result in different efficiencies for charge generation. We investigate this difference for four different 2-pyridyl diketopyrrolopyrrole (DPP) polymer-fullerene solar cells. By comparing the external quantum efficiency spectra...

Wide-Bandgap Benzodithiophene-Benzothiadiazole Copolymers for Highly Efficient Multijunction Polymer Solar Cells.

Advanced materials (Deerfield Beach, Fla.)

Adv Mater. 2015 Aug;27(30):4461-4468. doi: 10.1002/adma.201501626. Epub 2015 Jul 02.

Novel wide-bandgap semiconducting polymers are designed and synthesized for multijunction polymer solar cell (PSC) applications. In single-junction PSCs, BDT-FBT-2T exhibits efficiencies exceeding 6.5% for active layer thicknesses between 90 and 250 nm, with the highest efficiency of 7.7% at...

A real-time study of the benefits of co-solvents in polymer solar cell processing.

Nature communications

PMID: 25656313
Nat Commun. 2015 Feb 06;6:6229. doi: 10.1038/ncomms7229.

The photoactive layer of organic solar cells consists of a nanoscale blend of electron-donating and electron-accepting organic semiconductors. Controlling the degree of phase separation between these components is crucial to reach efficient solar cells. In solution-processed polymer-fullerene solar cells,...
