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.

Heterojunction Photoanode of Atomic-Layer-Deposited MoS on Single-Crystalline CdS Nanorod Arrays.

Cadmium sulfide (CdS) is a semiconducting absorber for photoelectrochemical (PEC) hydrogen production with suitable electronic band structures. However, it suffers from severe photocorrosion and rapid charge recombination during the desired PEC reactions. Herein, we describe the identification of the optimal junction thickness of CdS/MoS core/sheath heterojunction nanostructures by employing atomic layer deposition (ALD) techniques.

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.
