Comments Off on Futuristic art center in China has detachable rooms that can bike around town

People’s Architecture Office just unveiled a futuristic cultural center in China that is equipped with detachable room that serve as “cultural satellites.” The incredible building – called the People’s Station – uses the flexible mini-structures to add extra space when necessary. When not in use, the mini-buildings can be collapsed and transported by bike to other locations. The architects used their own prefabricated system to manufacture the building, which took just three months to construct. Located in a quiet region of Yantai, the building’s design was created to attract visitors to the historic center of the city. Its funky angular volume is comprised of wide open entryways and various sections that seem to float off the ground. Related: China’s new futuristic library is unlike any we’ve seen before On the inside, the exhibition rooms are the first two floors are expansive, with high ceilings that are staggered up diagonally up to the second and third floors. Triangular glass panels flood the interior with natural light . On the top floor, visitors can enjoy a lounge area with a bookstore and a cinema. Throughout the building, there are various outdoor terraces that offer beautiful views of surrounding cityscape, as well as the ocean in the distance. + People’s Architecture Office Via Archdaily Photography courtesy PAO

SunPower shingles solar cells to boost solar panel efficiency by 15%

Comments Off on SunPower shingles solar cells to boost solar panel efficiency by 15%

SunPower has achieved a 15 percent efficiency increase in its panels in part by incorporating a novel design: shingling solar cells. For only $9 in additional costs from adding solar cells, the San Jose -based manufacturer’s P Series solar panels can be structured like shingles, maximizing direct sunlight exposure and raising efficiency. Many of the new designs incorporated into the P Series solar panel were created by Cogenra, a solar panel producer based in Fremont, California, which was acquired by SunPower in 2015. Because of this increase in efficiency through a relatively simple design tweak, SunPower’s stock jumped 12 percent as investors recognized the profit potential for these new panels. Although SunPower has had trouble achieving profitability in recent years, its new designs are promising. Unlike previous designs from the company, the P Series solar panels utilize cheaper, lower efficiency solar cells and make up for the efficiency loss through their shingling design. By shingling the solar cells, the space between cells is reduced, allowing more cells to be included on each panel. As a result, nearly 100 percent of the panel is covered with solar cells. Related: New rooftop solar hydropanels harvest drinking water and energy at the same time The P Series also incorporates a design that relocates ribbons and solder bands to the back of the panel, once again making room for additional solar cells facing the sun. This innovation and others have enabled the P Series to achieve a much more affordable production price. Investors had previously expressed concerns over the high capital investment required to build new SunPower factories and the high cost of its earlier model panels. To prepare for a broader stake in the market, SunPower, in collaboration with Dongfang Electric and silicon giant Zhonghuan Semiconductor, will build what is expected to be the largest solar manufacturing facility on the planet. This joint project has been dubbed DZS Solar. Via Electrek Images via SunPower (1)

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.

Comments Off on Lightyear unveils solar-powered car with a 500-mile driving range

A little-known Dutch startup called Lightyear just unveiled plans for a solar-powered electric car with a 500-mile driving range. The Lightyear One features a four-wheel drive powertrain that can handle rough terrain – and thanks to its solar panels, it can drive for months without having to be charged. “You can think of the Lightyear One as being as an electric car redesigned from the ground up to combine the best of solar cars and electric cars.”, says Lex Hoefsloot, CEO of Lightyear. “It’s a revolutionary step forward in electric mobility because we are able to combine a great look with extreme efficiency. This first model makes science fiction become reality: cars powered using just the sun”. Related: The world’s most efficient 5-seater car is powered entirely by the sun The solar-powered Lightyear One can travel up to 500 miles on a single charge. Other automakers have unveiled electric cars with solar panels on the roof, but none of them have been able to propel a car as far as Lightyear’s new vehicle. The integrated solar cells on the roof of the Lightyear One will generate enough energy to recharge the battery during the day, rendering charging virtually unnecessary. In sunny climates, the car can drive for months without charging, but if you need to travel further, you can also charge it using a standard power socket. Since the Lightyear One doesn’t need to rely heavily on charging infrastructure , the solar-powered car is a new option for drivers that don’t have access to a charger. “The Lightyear One is a statement to show that electric cars are ready for every corner of the planet”, Hoefsloot says. “It is the first step in our mission to make electric cars available for everyone”. The Lightyear One will be unveiled in early 2018, with the first deliveries in the United States and Europe expected to arrive in 2019. Pricing starts at 119,000 Euros, and reservations are already being taken on Lightyear’s website . Images @Lightyear + Lightyear

Indian ‘fruit of the gods’ could lower cost of solar cells by 40%

Comments Off on Indian ‘fruit of the gods’ could lower cost of solar cells by 40%

Could India’s ‘fruit of the gods’ help lower the price of solar cells ? Scientists at the Indian Institute of Technology (IIT) Roorkee discovered jamun, a black plum, contains a pigment able to absorb sunlight. They think utilizing the fruit in mass production of solar panels could slash costs. Jamun, Syzygium cumini , is indigenous to south Asia and is sold on the street for cheap prices. Jamun trees can grow to be nearly 100 feet tall and live for 100 years, and the black plums from those trees are lauded for medicinal and nutritional value. But now they may play a role in generating clean energy as well, thanks to their pigment anthocyanin. Related: India doubles down on solar power with huge park capacity increase IIT-Roorkee assistant professor Soumitra Satapathi told Quartz India, “We were looking at why the jamuns are black. We extracted the pigment using ethanol and found that anthocyanin was a great absorber of sunlight.” Satapathi and two other researchers from the institute used that anthocyanin as a sensitizer in dye sensitized solar cells (DSSCs). They think utilizing naturally occurring dyes, like the jamun pigment, could lower solar panel costs by 40 percent. Anthocyanin is also found in blueberries, raspberries, cherries, and cranberries. DSSCs aren’t as efficient as traditional silicon-based solar cells yet, but could offer a low cost alternative – beneficial especially for India as the country aims to gain 40 percent of energy from renewables by 2030. But the IIT scientists aren’t quite there yet; their DSSCs only have an efficiency of 0.5 percent, contrasted with traditional solar cells’ efficiency of over 15 percent. Nevertheless, the scientists pointed out jamun is widely available, and could offer a biodegradable , non-toxic alternative to synthetic dyes that have been used in DSSCs. The IEEE Journal of Photovoltaics published the research online recently. Via EcoWatch and Quartz India Images via Dinesh Valke on Flickr and Wikimedia Commons

Comments Off on Panasonic investing $256M in Tesla’s Buffalo solar manufacturing plant

Following Tesla ’s recent acquisition of SolarCity, the California-based company just scored another big win. Panasonic will invest more than $256 million in Tesla’s New York solar cell factory. The Japan-based electronics company is already partnering with Tesla to build electric car batteries at its Nevada Gigafactory, and this investment, announced December 27, positions Panasonic more firmly in the automotive industry than ever before, marking the fulfillment of the company’s’s gradual shift away from consumer electronics. Tesla’s production facility in Buffalo is expected to be up and running within just a few months. According to Tuesday’s announcement, production of photovoltaic (PV) cells and modules will begin in the summer of 2017. By 2019, the two companies expect to be churning out the equivalent of one gigawatt of solar power modules each year. Related: Tesla taps Panasonic to build solar panels for their Powerwall and Powerpack systems The news of Panasonic ’s hefty investment in the Buffalo manufacturing plant is the first development since Tesla first named the electronics company as its partner in mid-October, which was contingent on the completion of Tesla’s merger with SolarCity . While that initial announcement came with very few details (in part because the merger wouldn’t be finalized for another month), this update illustrates the enormous scope of Panasonic’s commitment to the solar power market. The PV modules Panasonic produces at Tesla’s facility will be used primarily in the Powerwall and Powerpack systems, Tesla’s off-grid power solutions. While Tesla’s “solar roof” is still on deck, there is no word on when production on that line might begin. SolarCity previously promised the creation of over 1,400 jobs at the Buffalo facility and Tesla’s announcement Tuesday reaffirms that commitment and elaborates that the figure includes more than 500 manufacturing jobs—an important footnote for a city that once relied heavily on blue collar industries like steel and automotive manufacturing.
