Comments Off on World’s largest mural unveiled in Russia

Moscow-based creative art association, Artmossphere has just unveiled what looks to be the world’s largest mural. Painted by legendary Russian urban artist, Misha Most , the elaborate art piece called Evolution-2 spans a whopping 10,800 square meters on the side of an old industrial complex in the Russian town of Vyksa. Working with five assistants, Most took 35 days to paint the large mural onto the expansive wall of the Vyksa metallurgical plant. The work took 35 days and was recently unveiled at the Art Ovrag festival . The project was dedicated to the 25th anniversary of the United Metallurgical Company (OMK) and the 260th anniversary of the Vyksa metallurgical plant.

The essential graphic element of the project is a scientist, a robotized man, a human-like android, as well as the elements of Chemistry, Physics and other sciences. I tend to visualize the thoughts in the investigator’s head.” Although the Guinness World Records are reportedly considering the inclusion of Most’s work for the world record of largest mural painted by one artist, it has not been made official yet. + Misha Most + Artmossphere + Art Ovrag Photography via Artmossphere

New stacked solar cell absorbs energy from almost the entire solar spectrum

Comments Off on New stacked solar cell absorbs energy from almost the entire solar spectrum

Most traditional solar cells aren’t able to convert long-wavelength photons into electricity . A team of researchers led by Matthew Lumb at The George Washington University is hoping to change that in order to capture more power. They’ve designed a solar cell that can harvest just about all of the energy in the solar spectrum – and could become the world’s most efficient solar cell with an efficiency of 44.5 percent. The scientists created a prototype of their solar cell that differs from most others: they stacked multiple solar cells to create a single device that can capture nearly all the solar spectrum’s energy. And as opposed to the solar panels that adorn many rooftops , this new solar cell utilizes concentrator photovoltaic (CPV) panels that concentrate sunlight onto micro-scale cells using lenses. Related: SunPower nabs record for world’s most efficient rooftop solar panel The cell works something like a sieve for sunlight, as each layer absorbs a certain set of wavelengths, to capture nearly half of available energy – most traditional cells only capture around one quarter. Efficiency is one of the main goals of any researcher working on solar cells, and these scientists obtained what could be the highest efficiency in the world using materials based on gallium antimonide (GaSb) substrates. A technique called transfer-printing allows the tiny cells to be constructed with great precision. But this groundbreaking solar cell wasn’t cheap. Still, though the materials utilized were expensive, the scientists think the technique to build the cells is promising to show how efficient a solar cell could be. In the future they think a similar product could hit markets “enabled by cost reductions from very high solar concentration levels and technology to recycle the expensive growth susbtrates.” The journal Advanced Energy Materials published the research this week. 12 scientists from the United States Naval Research Laboratory and other American institutions collaborated with Lumb on the paper.
