Improving thermoelectric properties by high temperature annealing
TL;DR: In this article, a method for improving thermoelectric properties of alloys by subjecting them to one or more high temperature annealing steps, performed at temperatures at which the alloys exhibit a mixed solid/liquid phase, followed by cooling steps.

Broadband Metamaterial Absorbers
TL;DR: In this article, a photovoltaic cell includes a light absorbing layer capable of absorbing solar energy and converting the absorbed energy into electrical current; a perforated conductive film disposed on a light-absorbing surface of the light absorbing material; and a rear electrode disposed on an opposite surface of a surface of an absorbing layer opposite to the light-absorbant surface, where the rear electrode and the conductive material are in electrical communication with the absorbing material to collect electrical current generated in the lightabsorber.
