The IBCs' patent-pending innovations complete thermal isolation, the ability to test large cells and batteries, and the features needed to test high energetic batteries safely provide a level of accuracy and functionality not seen in other calorimeters. Precisely measuring heat generation helps optimize battery thermal-management systems to extend battery life and improve safety at an affordable cost. With forecasts of more than half a million hybrid and electric cars this year and with manufacturers needing to meet increased fuel efficiency requirements the IBCs allow auto manufacturers to address safety and efficiency issues long before drivers have to rely on the battery packs to get them home safely.
NREL's Isothermal Battery Calorimeters team included Matt Keyser, Ahmad Pesaran, John Ireland, Dirk Long, and Mark Mihalic. The NETZSCH team included Peter Ralbovsky, Jean-Francois Mauger, and Gilles Widawski.
TetraSun's High-Efficiency, Cost-Effective Mono-crystalline Solar Cells
TetraSun, now a division of First Solar, Inc., has developed an innovative cell architecture and manufacturing process with the potential to break the historical tie between high-efficiency and high-cost photovoltaic energy generation and represents an important step toward economically and environmentally compelling alternatives to fossil fuel-based energy production.
Relative to conventional crystalline solar cells, TetraSun's proprietary architecture allows for a greater percentage of incoming sunlight to be converted to electricity. Additionally, the company has reduced the typical manufacturing cost of high-efficiency solar cells with a more streamlined, simplified process flow and the elimination of certain costly materials. For instance, TetraSun's metallization process replaces silver, a high-cost commodity used in traditional screen printed solar cell
