Solar Thermoelectric Generators Making News
Thermoelectric devices, which convert heat to electricity, can be used to convert solar power into electrical power. The devices comprise a surface which absorbs the sun's heat; a heat sink that stays at a fixed temperature; and a thermoelectric material between the absorber and the heat sink which converts this temperature difference into an electrical current. The recent NanoEngineering Group paper by Kraemer et. al, published in Nature Materials, has garnered a good deal of press. Read coverage from MIT News or The Economist.

Science Express Paper: High-Thermoelectric Performance of Nanostructured Bismuth Antimony Telluride Bulk Alloys
Here we show that a peak ZT of 1.4 at 100°C can be achieved in p-type nanocrystalline bismuth antimony telluride bulk alloy. These nanocrystalline bulk materials were made by hot-pressing nanopowders ball-milled from crystalline ingots under inert conditions. More importantly, ZT is about 1.2 at room temperature and 0.8 at 250C, which makes these materials useful for cooling and power generation. This discovery sets the stage for use of a new nanocomposite approach in developing high performance low-cost bulk thermoelectric materials. Full article
