Concentrix Solar Enters the US Market With Megawatt CPV Deployment at a Chevron Facility

Concentrix Solar, a leading supplier of Concentrator Photovoltaic (CPV) systems and a new division of the Soitec Group (Euronext Paris), the world's leading supplier of engineered substrates, announced today that it has signed a contract with Chevron Technology Ventures for the deployment of a one megawatt (MW) CPV power plant to be installed at a Chevron Mining facility in Questa, New Mexico, USA.

Kavli Prize Science Forum announced

The Norwegian Academy of Science and Letters, in partnership with The Kavli Foundation and the Norwegian Ministry of Education and Research, has announced the establishment of the Kavli Prize Science Forum - a new biennial international forum meeting to facilitate high-level, global discussion of major topics on science and science policy.

Improved design for dye-sensitized solar cells includes quantum dot antennas

While the dye sensitized photovoltaic cell is a fairly mature design, researchers are still trying to improve its efficiency with various techniques, including structuring nanoporous electrodes to provide higher surface area and better charge transport, replacement of the liquid electrolyte by a solid one in order to prevent the electrolyte evaporation, and ways to widen the narrow absorption spectra of molecular dyes. In a standard DSSC, an organic molecule adsorbed on the surface of a porous electrode absorbs light and then initiates the charge separation process eventually leading to generation of photocurrent. One major difficulty in such cells is that very few dyes can absorb a broad spectral range, essentially covering the solar spectrum. In contrast, broad spectral coverage is an inherent property of semiconductor nanocrystals. The latter, however, turn out to do a rather lousy job in separating the charges. Researchers in Israel have now presented a new configuration for quantum dot sensitized DSSCs via a FRET process.
