Comments Off on Street Artist Hyuro to Turn Copenhagen Street into Denmark’s Longest Artwork

Danish authorities decided that a long street in Copenhagen needed a makeover, so they hired Spanish artist Hyuro to transform the corridor into the nation’s longest piece of street art ! Once completed, the finished work will stretch 271 meters long as it enlivens what was previously a bland grey street.

Using Light to Make Solar Panels

Comments Off on Using Light to Make Solar Panels

A new optical furnace that uses intense light rather than a conventional furnace to heat the silicon to make solar cells saves about half the energy needed . The process uses a furnace with “highly reflective and heat-resistant ceramics to ensure that the light is absorbed only by a silicon wafer, not by the walls inside the furnace.” The process was developed by scientists at the National Renewable Energy Laboratory (NREL). In addition to providing improved efficiency in the production of the cells, the optical furnace also does a better job at removing some impurities, which makes for better output from the finished panels. Eventually, researchers on the project believe that this could provide a four percentage point increase in the efficiency of the solar cells produced with this method. image credit: NREL/Dennis Schroeder via: Treehugger

Higher Efficiency with Quantum Dot Solar Cells

Comments Off on Higher Efficiency with Quantum Dot Solar Cells

Photovoltaic technology has taken another step forward as researchers at the National Renewable Energy Laboratory (NREL) have demonstrated a photocell with an external quantum efficiency over 100 percent using quantum dots . The new cell uses a process called Multiple Exciton Generation (MEG) that produces more than one electron-hole pair per absorbed photon, and reached a level of 114 percent. This development offers the possibility of increased efficiency in solar panels, and the technology is able to be manufactured using high-throughput roll-to-roll manufacturing. With the use of quantum dots, photocells could theoretically see as much as a 35 percent increase in power conversion efficiency above contemporary cells. The research cell was constructed as a “layered cell consisting of antireflection-coated glass with a thin layer of a transparent conductor, a nanostructured zinc oxide layer, a quantum dot layer of lead selenide treated with ethanedithol and hydrazine, and a thin layer of gold for the top electrode.” Note that this does not mean that the entire panel would have a total efficiency above 100% (which would be thermodynamically impossible). The quantum efficiency means only that the number of electron-hole pairs created in the cell is greater than the number of photons that are absorbed. Nonetheless, the advance provided by MEG could lead to the next generation of even more efficient solar energy collectors. image: Lawrence Berkeley Lab and CC-BY-SA 3.0 by Opticks3
