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 »

More Efficient, Self-cleaning Solar Cells

Written by , on March 17, 2014

Researchers from Changchun University of Science and Technology, Xi’an Technological University and Cardiff University have found that a patterned layer on top of the active part of a solar panel can avoid the energy losses due to reflection from the surface. They have devised an approach to the lithographic process used to “print” microelectronic circuits […]  Read more »

Solar Power at Night?

Written by , on March 11, 2014

Physicists at the Harvard School of Engineering and Applied Sciences, led by Federico Capasso, a world-renowned expert in semiconductor physics, photonics and solid-state electronics, have proposed a device that would harvest energy from Earth's infrared emissions into outer space. The device would consist of a "hot" plate at the temperature of the Earth and air, […]  Read more »

Drones to Collect Solar and Wind Energy

Written by , on February 12, 2014

New Wave Energy, an English company, has plans to build a high altitude aerial power plant, consisting of networks of unmanned drones that can harvest solar and wind energy and transmit it wirelessly to receiving stations on the ground. As sunlight radiates down to the Earth's surface some of its energy is absorbed into the […]  Read more »

Using Steam Engine Technology for Power Storage

Written by , on November 30, 2013

A group of Australian engineers has formed a company, Terrajule, to develop a novel energy storage solution. The Terrajoule system combines concentrated solar thermal energy, steam engines and an integrated storage system using an insulated pressure vessel. The concentrated solar thermal energy is used to produce steam. Since it is impractical to store steam for […]  Read more »

Falling Particle Solar Thermal Power

Written by , on September 17, 2013

Engineers at Sandia National Laboratories in New Mexico, and partner institutions, are using a falling particle receiver to more efficiently convert the sun's energy to electricity in large-scale, concentrating solar power plants. The falling particle receiver developed at Sandia drops sand-like ceramic particles through a beam of concentrated sunlight and captures and stores the heated […]  Read more »

Solar – a $77 billion Industry

Written by , on August 21, 2013

Bollomberg has created this short video of facts about the state of the solar industry. It emphasises how global solar energy capacity has soared in the past 5 years yet Earth's most abundant energy source still provides only a fraction of our total energy.  Read more »
