Scientists have designed a novel type of nanoscale solar cell. Initial studies and computer modelling predict these cells will outperform traditional solar panels, reach power conversion levels by over 40 percent.

Solar power cells work through the conversion of sunlight into electricity using photovoltaics. Here solar energy is converted into direct current. A photovoltaic system uses several solar panels; with each panel composed of a number of solar cells. This combines to create a system for the supply usable solar power.

To investigate what is possible in terms of solar power, the researchers have examined the Shockley-Queisser limit for different materials. This equation describes the maximum solar energy conversion efficiency achievable for a particular material, allowing different materials to be compared as candidates for power generation.

We’ve known there is water on Enceladus for a while now, but NASA has just confirmed a more recent theory about the icy moon of Saturn: it has a subsurface ocean that spans the entire globe. The news comes just a handful of months after the agency discovered evidence of hydrothermal vents, which are believed to be integral to the formation of life here on Earth.

The confirmation was made using research from Cassini — a spacecraft that arrived at Saturn in 2004 and has spent the last decade studying the planet and its many moons. (It was launched in 1997.) The researchers used Cassini to measure the wobble in Enceladus’ orbit of Saturn, something that “can only be accounted for if its outer ice shell is not frozen solid to its interior.”

We’ve been hearing and seeing plenty about augmented reality these days — from Microsoft’s HoloLens to the mysterious Google-backed startup Magic Leap — but aside from the gee-whiz factor, its benefits can sometimes feel almost as illusory as virtual images. Gaia Dempsey, managing director of DAQRI, which makes an AR-enabled smart hard hat, offers up a strong case for why augmented reality is more than just hype. In a new video for the upcoming Future of Storytelling Summit (which also produced the stunning video of animation legend Glen Keane drawing in VR), Dempsey explains how AR could fundamentally change the way we learn and experience the world. For example, it’s one thing to be told how the mechanics of a clock works in text or video, it’s an entirely different experience to be able to manipulate a moving set of clock gears in three dimensions.

Remember Iron Man’s transparent smartphones They might become reality sooner than you think thanks to an unusual new type of battery that’s not only transparent, but it can also charge via solar power. The technology could also be used for other products in the future, such as smart office and home windows that would be able to let the sun’s light pass through them, but also recharge and store energy.

Developed by a team of researchers at the Kogakuin Univeristy, the lithium ion battery is not entirely transparent, as it contains the same chemical compounds that make any battery work. Furthermore, when exposed to sunlight, the battery becomes slightly tinted, transmitting 30% less light – but it’s still transparent. When fully discharged, the light transmittance rises to approximately 60 percent, TechXplore reports.

Researchers from Queen Mary University of London and Karlsruhe Institute of Technology have developed a model that applies ideas from the theory of complex networks, such as the brain or the Internet, to the fundamental quantum geometry of space-time.

The research is published in Scientific Reports with the title “Complex Quantum Network Manifolds in Dimension d > 2 are Scale-Free.” The research paper is freely available online.

“We hope that by applying our understanding of complex networks to one of the fundamental questions in physics we might be able to help explain how discrete quantum spaces emerge,” said author Ginestra Bianconi.
