Tubular Solar Panels Create Electricity, Hot Water

These tubes, developed by Naked Energy, in Guildford, England, are a kind of hybrid solar-energy contraption that make more efficient use of the sun's energy to produce both electricity and hot water.

Silicon's future replacement in solar PV?
The best known material used in solar cells is silicon, but that might change in the future; graphene, the wunderkind material for which we keep finding new uses, just like its cousin the carbon nanotube, is proving to have very promising qualities for converting light (photons) into electricity (electrons).
The reason behind it:
Conventional materials that turn light into electricity, like silicon and gallium arsenide, generate a single electron for each photon absorbed. Since a photon contains more energy than one electron can carry, much of the energy contained in the incoming light is lost as heat. Now, new research reveals that when graphene absorbs a photon it generates multiple electrons capable of driving a current. This means that if graphene devices for converting light to electricity come to fruition, they could be more efficient than the devices commonly used today

Japan Hopes to Have Solar Power Transmission in Space by 2030

The future of air travel may not be gigantic turtle-shaped airships, but Japan hopes to test another idea straight out of science fiction, solar power stations in space, within the next two decades.

Scientific American is running a piece in their June issue which discusses the ambitious, orbital solar energy plans currently being discussed by Japan’s space agency. Without giving it all away, here are the main points:

Laser or Microwave to trasmit energy to EarthThe plan would consist of a solar-power generator in geostationary orbit which would collect the solar energy and transmit it in either microwave or laser form to a receiving station on the planet surface.

The form this research is currently taking is a bit more grounded: An 800 watt optical-fiber laser is fired at a receiving station 500 meters away. This beam is bounced off a mirror that reflects only 1,064-nanometer wavelength light—the frequency found to most easily pass through the Earth’s atmosphere. This beam would carry the solar energy to a receiving station back on Earth. The key task at the moment is finding a material that efficiently can convert sunlight into a laser beam.

Project would be massive, physically and financiallyIf and when this project is completed, it is envisioned that it will have to be physically massive, let alone costly: the orbiting solar portion could stretch for kilometers and weight 10,000 tonnes; the laser portion could be as long as 10 kilometers; the ground-based receiving unit could be up to two kilometers long. The whole project could cost tens of billions of dollars, according to Hiroaki Suzuki, one of the 180 scientists working on the scheme.

Japan is not the first nation to explore the possibilities of harnessing solar energy from space: India and Palauhave also vetted the idea. As you might expect, the Pentagon also thinks orbiting solar panels are worth investigating

What Will the Solar PV Market Look Like in 2016?

Four years is a long time in the solar industry. Think about what's happened in the U.S. industry since 2009: We've seen a recession, a massive boom in federal spending, a precipitous drop in solar module prices, a wave of bankruptcies, a nasty trade battle with China, a slowdown in utility-scale projects, a strong gain in residential projects, and a now a massive retraction in federal spending. Amidst it all, solar installations continue to grow.

It's anyone's guess what the next four years will bring. But the analysts at GTM research are always thinking about what's coming down the pike. And the Greentech Media Solar Summit next month is the perfect place to hear from our analysts and other professionals in the industry about what they're seeing on the ground.

Take a look at this chart from GTM Research showing the differences between 2012 and 2016:
