Highly efficient polymer solar cells cast from non-halogenated xylene/Anisaldehyde solution
Energy and Environmental Science, 2020Co-Authors: Christian Sprau, Dominik Landerer, Manuel Koppitz, F. Buss, Daniel Bahro, Alexander Schulz, Philip Scharfer, Wilhelm Schabel, Michael Wagner, Alexander ColsmannAbstract:Several high performance polymer:fullerene bulk-heterojunction photo-active layers, deposited from the non-halogenated solvents o-xylene or anisole in combination with the eco-compatible additive p-Anisaldehyde, are investigated. The respective solar cells yield excellent power conversion efficiencies up to 9.5%, outperforming reference devices deposited from the commonly used halogenated chlorobenzene/1,8-diiodooctane solvent/additive combination. The impact of the processing solvent on the bulk-heterojunction properties is exemplified on solar cells comprising benzodithiophene-thienothiophene co-polymers and functionalized fullerenes (PTB7:PC71BM). The additive p-Anisaldehyde improves film formation, enhances polymer order, reduces fullerene agglomeration and shows high volatility, thereby positively affecting layer deposition, improving charge carrier extraction and reducing drying time, the latter being crucial for future large area roll-to-roll device fabrication.

formation of Anisaldehyde via hydroxymethylation of anisole over sno2 ceo2 catalysts
Catalysis Letters, 2000Co-Authors: T M Jyothi, M B TalawarAbstract:Hydroxymethylation of anisole has been carried out over SnO2–CeO2 catalysts in the temperature range 623–723 K. Methoxybenzaldehyde (Anisaldehyde) and condensation products were formed along with minor quantities of methoxybenzyl alcohol, o‐cresol, phenol and 2,6‐xylenol. A maximum Anisaldehyde selectivity of 64% was obtained at 623 K at an anisole conversion of 46% under optimized conditions. Catalytic activity of these systems in the formation of aldehyde is ascribed to the presence of weak acid sites and redox metal sites.
