New Schottky-Type Wire-Based Solar Cell with NiSi Nanowire Contacts.

Solar cells built with arrays of semiconductor wires have been studied for several years. They present some potential advantages over their bulk counterparts, such as (much) less use of semiconductor material, as well as improved light absorption properties. Most wire-based solar cells are fabricated with arrays of semiconductor p-n junctions, either radial or axial.

Surface Engineering of Room Temperature-Grown Inorganic Perovskite Quantum Dots for Highly Efficient Inverted Light-Emitting Diodes.

Inorganic cesium lead bromide quantum dots (CsPbBr QDs) are usually synthesized via a high-temperature process (hot injection, HI). This process is similar to that used for the synthesis of other semiconductor QDs (i.e.

Graphene-Coated Aluminum Thin Film Anodes for Lithium-Ion Batteries.

We present a detailed study on graphene-coated aluminum thin films for Li-ion battery anode applications. The best electrode ageing behavior is obtained for Al films encapsulated with four porous graphene layers. Graphene encapsulation prevents "crushed" Al nanoparticles from detaching from the anode, thus allowing prolonged charge-discharge cycling.

Ligand removal and photo-activation of CsPbBr quantum dots for enhanced optoelectronic devices.

Perovskite quantum dots have recently emerged as a promising light source for optoelectronic applications. However, integrating them into devices while preserving their outstanding optical properties remains challenging. Due to their ionic nature, perovskite quantum dots are extremely sensitive and degrade on applying the simplest processes.

Rubidium as an Alternative Cation for Efficient Perovskite Light-Emitting Diodes.

Incorporation of rubidium (Rb) into mixed lead halide perovskites has recently achieved record power conversion efficiency and excellent stability in perovskite solar cells. Inspired by these tremendous advances in photovoltaics, this study demonstrates the impact of Rb incorporation into MAPbBr-based light emitters. Rb partially substitutes MA (methyl ammonium), resulting in a mixed cation perovskite with the formula MARb PbBr.
