Solar Technologies Garner Two R&D 100 Awards
R&D Magazine selected two SunShot-funded solar technologies to be among the 100 most significant innovations of 2013.
- Solar Glare Hazard Analysis Tool (SGHAT): Sandia National Laboratories has developed SGHAT, a Web-based tool and methodology to evaluate potential glare hazards associated with solar energy installations. As increasing numbers of solar installations are deployed, glare is a growing concern due to its potential impact on pilots, air traffic controllers, and motorists. SGHAT addresses new federal guidelines requiring quantified assessments of glare from proposed solar installations. The tool can quickly locate a site, outline the proposed array, and identify glare throughout the year, calculating the glare’s intensity and size to predict potential ocular hazards. The tool can also predict the annual energy production of proposed arrays and evaluate alternative designs, layouts, and locations to identify configurations that maximize energy production while mitigating glare impact.
- TetraCell Solar Cells: TetraSun, in partnership with the National Renewable Energy Laboratory (NREL) under a SunShot Incubator award, has developed an innovative solar cell architecture and manufacturing process with the potential to break the historical tie between high-efficiency and high-cost photovoltaic energy generation. Relative to conventional crystalline silicon solar cells, TetraSun's proprietary cell architecture allows 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. NREL performed characterization and reliability measurements on modules manufactured with TetraSun cells and collaborated with the company’s technical team to develop and implement modifications to the measured modules, contributing to improved product performance and reliability.
