3D TiO2 photoanodes in dye-sensitized solar cells (DSCs) are fabricated by the soft lithographic technique for efficient light trapping. An extended strategy to the construction of randomized pyramid structure is developed by the conventional wet-etching of a silicon wafer for low-cost fabrication. Moreover, the futher enhancement of light absorption resulting in photocurrent increase is achieved by combining the 3D photoanode with a conventional scattering layer.

Tetracyanchinodimethan (TCNQ) auf Silbernanopartikeln (AgNPs) induziert hohe positive Oberflächenladungen, die einen Grenzflächendipol erzeugen, über den sich die Energieniveaus der AgNPs einstellen lassen (siehe Bild). Poly(vinylpyrrolidon)‐Membranen, die dispergierte AgNPs mit TCNQ enthalten, zeigen eine hohe Selektivität bei der Trennung gasförmiger Olefin‐Paraffin‐Gemische.

Calling the tune: High positive surface charges induced by tetracyanoquinodimethane (TCNQ) allow tuning of the energy levels of silver nanoparticles (AgNPs) through an interface dipole (see picture). Facilitated transport membranes containing AgNPs with TCNQ dispersed in poly(vinylpyrrolidone) show high mixed‐gas selectivity for the separation of olefin/paraffin mixtures.
