Enhancing the ferroelectric performance of P(VDF-co-TrFE) through modulation of crystallinity and polymorphismFacility for Printed Organic Electronics

The functional properties of P(VDF- co -TrFE) are strongly dependent on its structure, which, in turn, depends on processing conditions applied. In this work we investigate the P(VDF- co -TrFE) processing-structure-function relationships, in order to find the thermal conditions that result in optimum ferroelectric performance in thin film configuration. Our results show that annealing...

Synthesis of Bioinspired Curcuminoid Small Molecules for Solution-Processed Organic Solar Cells with High Open-Circuit VoltageFacility for Printed Organic Electronics

Borondifluoride complexes of curcuminoid derivatives end-capped with triphenylamine groups were designed for solution-processed bulk-heterojunction organic solar cells. They were obtained very simply in a one-pot synthesis from cheap building blocks. Compared to push–pull systems based on borondifluoride complexes of hydroxychalcones, curcuminoids present the donor–acceptor–donor electronic...

Aqueous PCDTBT:PC71BM Photovoltaic Inks Made by NanoprecipitationFacility for Printed Organic Electronics

The fabrication of organic solar cells from aqueous dispersions of photoactive nanoparticles has recently attracted the interest of the photovoltaic community, since these dispersions offer an eco‐friendly solution for the fabrication of solar cells, avoiding the use of toxic solvents. In this work, aqueous dispersions of pure...

Photoactive donor-acceptor composite nanoparticles dispersed in waterFacility for Printed Organic Electronics

A major issue that inhibits the large-scale fabrication of organic solar modules is the use of chlorinated solvents considered to be toxic and hazardous. In this work, composite particles of poly[ N -9′-heptadecanyl-2,7-carbazole- alt -5,5-(4,7-di-2-thienyl-2′,1′,3′-benzothiadiazole] (PCDTBT) and [6,6]-phenyl C71 butyric acid methyl ester (PC 71 BM) were obtained in water from a versatile and a...

Highly ordered nanoring arrays formed by template Si-containing triblock terpolymer thin filmsFacility for Printed Organic Electronics

Laterally ordered nanorings with a periodicity of 38 nm are produced from the directed self‐assembly of poly(1,1‐dimethylsilacyclobutane)‐ block ‐polystyrene‐ block ‐poly(methyl methacrylate) thin films on topographically patterned substrates. Such nanoscale arrays with vertically oriented rings are highly desired in technological applications including memory using magnetic recording,...

Templated Sub-100-nm-Thick Double-Gyroid Structure from Si-Containing Block Copolymer Thin FilmsFacility for Printed Organic Electronics

The directed self-assembly of diblock copolymer chains (poly(1,1-dimethyl silacyclobutane)-block-polystyrene, PDMSB-b-PS) into a thin film double gyroid structure is described. A decrease of the kinetics of a typical double-wave pattern formation is reported within the 3D-nanostructure when the film thickness on mesas is lower than the gyroid unit cell. However, optimization of the solvent-vapor...
