Adapted Antennas Harness More Power From the Sun

A research team from Tel Aviv University is working on a solar panel composed of nano-antennas instead of semiconductors. By adapting classic metallic antennas to absorb light waves at optical frequencies, a much higher conversion rate from light into useable energy can be achieved.

Photosynthesis Helper Protein Discovered

Photosynthesis is less efficient in plants than it could be. Red algae, in contrast, use a slightly different mechanism and are thus more productive. Scientists from Germany's Max Planck Institute of Biochemistry (MPIB) have now identified a helper protein for photosynthesis in red algae.

Affordable Solar Option for Power Plants

Solar thermal power plants - which use high temperatures and pressure generated by sunlight to produce turbine movement - are an environmentally-friendly alternative to standard power plants. But this can be expensive, especially when it comes to equipment made from expensive metals and the solar high-accuracy concentrator technology used to harvest solar energy.

Composite Metamaterial for Solar Tech

A Northwestern University research team has developed a new material that absorbs a wide range of wavelengths and could lead to more efficient and less expensive solar technology. The researchers used two unconventional materials – metal and silicon oxide – to create thin but complex, trapezoid-shaped metal gratings on the nanoscale that can trap a wider range of visible light.
