      The image on the front cover shows the TEM photograph of a hierarchical structure composed of a ZnO nanorod surrounded by nanoporous ZnO for photovoltaic applications. The SAED pattern (top left) shows the hierarchical structure to be singlecrystalline. In their article on pp. 2252–2257, Servane Haller et al. report on the development of this structure. It shows a large surface area and an efficient carrier transfer of the electrons and is obtained by a two-step cathodic electrodeposition. Different geometries could be identified whether the hierarchical structures have grown enough to join themselves or not. The first moments of the electrodeposition of the nanoporous structure on the nanorods have been investigated and it revealed that a nanoporous layer is epitaxially deposited. The preliminary test of a dye-sensitized solar cell (DSSC) could be prepared with this structure that confirmed the interest of the concept.

      Article first published online: 6 OCT 2010 | DOI: 10.1002/pssa.201090022

      Nitride-based light-emitting diodes (LEDs) suffer from a reduction (droop) of the internal quantum efficiency with increasing injection current. This droop phenomenon is currently the subject of intense research worldwide, as it delays general lighting applications of GaN-based LEDs. Several explanations of the efficiency droop have been proposed in recent years, but none is widely accepted. In his Feature Article on pp. 2217–2225, Joachim Piprek provides a snapshot of the present state of droop research, reviews currently discussed droop mechanisms, contextualizes them, and proposes a simple yet unified model for the LED efficiency droop. This simple model considers both Auger recombination and carrier leakage as potential explanations of the efficiency droop. As both of these explanations exhibit some weaknesses, the search for additional and improved models of the LED efficiency droop continues.
