A fully transparent solar cell that could make every window and screen a power source

A fully transparent solar cell that could make every window and screen a power source
Back in August 2014, researchers at Michigan State University created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone’s screen) into a photovoltaic solar cell. Unlike other “transparent” solar cells that we’ve reported on in the past, this one really is transparent, as you can see in the photos throughout this story. According to Richard Lunt, who led the research at the time, the team was confident the transparent solar panels can be efficiently deployed in a wide range of settings, from “tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.” Now Ubiquitous Energy, an MIT startup we first reported on in 2013, is getting closer to bringing its transparent solar panels to market. Lunt cofounded the company and remains assistant professor of chemical engineering and materials science at Michigan State University. For more, read How do solar cells work?

How we can limit global warming to 1.5°C After the climate talks in Marrakech, our climate mission remains the same as what was set out in the 2015 Paris Agreeement: to eliminate all carbon dioxide emissions by the middle of this century. While the long-term focus is on 2050 or 2100, what matters now is the next ten years. If we miss bending the rising emissions curve downward by around 2020, we may well miss the chance to avoid the worst climate damage. We looked at all the major emitting sectors and the most recent scientific analyses of what can be done – and how fast – to come up with a list of the most important things to do in the next five to ten years to bend the emissions curve downwards. Here’s the good news: for all areas, we show signs that a transition of this magnitude is possible. In many cases, it’s already happening.

Roofing Product Makes Electricity, Heat, and Heats Water! A small terrace house in the inner Sydney suburb of Glebe is hosting what is believed to be the world’s first building integrated solar system that generates electricity as well as heat. The array combines thin-film solar PV and solar thermal technologies into a steel sheet roofing product produced by Australian steel manufacturer Bluescope, with assistance from the Australian Renewable Energy Agency. The top layer of the roofing product (pictured) generates electricity in the same way as solar PV modules – although it uses thin film technology for less weight and thickness – while heat is trapped and distributed between the two layers for use in water and space heating. The BIPVT installation is being hailed as a product that could one day be sold on Australian rooftops, although Bluescope is quick to point out that won’t be anytime soon. It has, however, said in the past that it feels it will be a cost competitive product for homes and businesses. It could also be used in retrofits.

Is D-Wave’s quantum processor really 10⁸ times faster than a normal computer? We have been following D-Wave's claims about its quantum hardware at Ars for a number of years. Over that time, my impression has oscillated between skepticism, strong skepticism, and mild enthusiasm. Back in November, D-Wave issued a press release that basically asked tech journalists to spray paint a finish line just behind their feet and break out a victory flag. It seemed a bit much. But now that D-Wave has declared victory, perhaps it's time to re-examine the skepticism. What exactly has D-Wave achieved, and does it constitute victory?

UK car shapes up for solar challenge Image copyright Solar Team Great Britain This is the super-sleek shape a British team hopes can bring it glory in next year's World Solar Challenge. The 3,000km race through the Australian desert, from Darwin to Adelaide, is the classic test for innovators trying to push the boundaries of what is possible with a Sun-powered vehicle. Solar Team Great Britain will be entering the event's Cruiser Class, which puts the emphasis on practicality as well as efficiency.

Energy Saving Trust Generate cheap, green electricity from sunlight Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun's energy using photovoltaic cells. These cells don't need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. The benefits of solar electricity Cut your electricity bills. A metal that behaves like water: Researchers describe new behaviors of graphene Graphene is going to change the world -- or so we've been told. Since its discovery a decade ago, scientists and tech gurus have hailed graphene as the wonder material that could replace silicon in electronics, increase the efficiency of batteries, the durability and conductivity of touch screens and pave the way for cheap thermal electric energy, among many other things. It's one atom thick, stronger than steel, harder than diamond and one of the most conductive materials on earth.

'World-first' solar car under development in Queensland could cost owners $250,000 By Alyssa Betts Posted A Queensland racing and research team is moving to become the world's first manufacturer of solar cars requiring road registration. It will cost more than $250,000 — and it may not even come with air-conditioning. The solar road in the Netherlands is working even better than expected The Netherlands made headlines last year when it built the world's first solar road - an energy-harvesting bike path paved with glass-coated solar panels. Now, six months into the trial, engineers say the system is working even better than expected, with the 70-metre test bike path generating 3,000 kWh, or enough electricity to power a small household for a year. "If we translate this to an annual yield, we expect more than the 70kwh per square metre per year," Sten de Wit, spokesman for SolaRoad, the group behind the project, told Tarek Bazley at Al Jazeera. So just imagine the potential if we covered all our roads in the stuff. It’s this kind of thinking that got the Internet so hyped-up over Solar Roadways last year - a crowd-funded project that aimed to power the entire US with solar-covered roads. However, the Netherlands became the first country to put the idea into practice with their installation in Krommenie, a town north of Amsterdam.

New molecular scissors cut out lingering HIV—maybe once and for all For the approximately 37 million people worldwide who are infected with HIV (human immunodeficiency virus), the newest cocktails of anti-retroviral drugs have come a long way in beating back the retrovirus and keeping an infection in check. Still, those drugs are no cure. While the treatments snarl the viral assembly line and thwart new infectious particles from invading the body’s cells, HIV itself is still there, hunkered in the DNA of a patient’s genome until there’s an opportunity for a comeback—say, when a patient goes off their medication. As long as there’s lingering HIV, patients must keep taking the drugs, which cause side-effects, make for high prescription bills, and raise the threat of drug resistance. At least, that's the case for now.
