Matched 'hybrid' systems may hold key to wider use of renewable energy
The use of renewable energy in the United States could take a significant leap forward with improved storage technologies or more efforts to "match" different forms of alternative energy systems that provide ...
Huge US solar plant lags in early production
The largest solar power plant of its type in the world—once promoted as a turning point in green energy—isn't producing as much energy as planned.
SolaRoad: World's first solar cycle path to open in the Netherlands
Imtech, in conjunction with the Province of Noord-Holland, Ooms Civiel, has developed the world's first solar road located in Krommwnie, Holland. The solar cycle path will be connected to the national grid ...
Chemical engineers borrow technique to store solar energy

New connection between stacked solar cells can handle energy of 70,000 suns
(Phys.org) —North Carolina State University researchers have come up with a new technique for improving the connections between stacked solar cells, which should improve the overall efficiency of solar ...
Carbon-based nanomaterials could lower cost of solar energy
When Mike Arnold thinks about solar energy, he thinks big, as in the "more than one-hundred-million-billion watts of sunlight that the Earth continuously bathes in." But he also thinks very, very small, exploring ...
Berkeley Lab scientists identify new driver behind Arctic warming
Scientists have identified a mechanism that could turn out to be a big contributor to warming in the Arctic region and melting sea ice.
How to make a "perfect" solar absorber
The key to creating a material that would be ideal for converting solar energy to heat is tuning the material's spectrum of absorption just right: It should absorb virtually all wavelengths of light that ...
Hybrid materials could smash the solar efficiency ceiling
(Phys.org) —A new method for transferring energy from organic to inorganic semiconductors could boost the efficiency of widely used inorganic solar cells.
New device stores electricity on silicon chips
(Phys.org) —Solar cells that produce electricity 24/7, not just when the sun is shining. Mobile phones with built-in power cells that recharge in seconds and work for weeks between charges.
Harvesting hydrogen fuel from the Sun using Earth-abundant materials
The race is on to optimize solar energy's performance. More efficient silicon photovoltaic panels, dye-sensitized solar cells, concentrated cells and thermodynamic solar plants all pursue the same goal: to ...
