Efficient New Solar Cell Material Can Also Emit Light

Written by , on April 27, 2014

Scientists at Nanyang Technological University have developed a solar cell material which can emit light as well as converting light to electricity. The new cells not only glow when electricity passes through them but they can also be customised to emit different colours.  Read more »

Storing Energy in Silicon Cells

Written by , on March 17, 2014

Researchers at Vanderbilt University in Nashville have devised a way to store electricity on a silicon-based supercapacitor that potentially would let mobile phones recharge in seconds and continue to operate for weeks without recharging. Whereas batteries store energy in chemical reactions, supercapacitors store electricity by assembling ions on the surface of a porous material. As […]  Read more »

Solar Cells That Also Store Energy

Written by , on June 19, 2013

Researchers at the University of Wisconsin in Madison has demonstrated the viability of a design for solar panels that can simultaneously generate electricity from sunlight and store the energy captured. As well as generating electricity in the usual way, the panels would also store electrons on zinc oxide nanowires coated with polyvinylidene fluoride polymer. The […]  Read more »

Better Solar Cells by Mimicking Moths’ Eyes

Written by , on May 28, 2013

In thin-film solar cells, which are made up of layered films, some of the sunlight is effectively lost at every film-to-film interface because of a phenomenon called "thin-film interference". Thin-film interference is what causes oil slicks on water to take on a rainbow-coloured appearance. Some light is reflected off the surface of the oil; some […]  Read more »

Aussie Printer Produces Solar Cells at 10 metres a Minute

Written by , on May 16, 2013

Rearchers at Australia's CSIRO have built a gigantic printer that spits out solar cells at a rate of about ten metres a minute. The printer system uses existing technology to embed polymer solar cells (also known as organic solar cells) in thin sheets of plastic. The A3-sized panels are created by laying a liquid photovoltaic […]  Read more »

IBM Cooling Tech to Cut Cost of Solar Power

Written by , on April 24, 2013

Scientists at Airlight Energy have joined IBM and the Swiss universities, ETH Zurich and Interstate University of Applied Sciences, to develop an affordable photovoltaic system that is capable of concentrating sunlight 2,000 times onto hundreds of one centimetre square PC cells – yielding high efficiency at low cost. The system uses a large parabolic dish […]  Read more »

Nanocellulose – 2. Recyclable Solar Cells

Written by , on April 22, 2013

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells on cellulose nanocrystal substrates. The cellulose substrates and made from plants and can be easily recycled at the end of their life. To date, organic solar cells have usually been fabricated on glass or plastic. Neither of these is easy to recycle […]  Read more »
