Solar panels can be used to provide heating and air conditioning

The use of solar panels to produce toilets hot water is standard practice, but researchers at the Madrid Universities Carlos III and Politécnica suggest that they may also be used to provide large offices with heating in ...

First algae powered building goes up in Hamburg

(Phys.org) —A 15-unit apartment building has been constructed in the German city of Hamburg that has 129 algae filled louvered tanks hanging over the exterior of the south-east and south-west sides of the building—making ...

Nanostructures triple organic solar cells efficiency

Princeton researchers have found a simple and economic way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.

New 'metamaterial' practical for optical advances

(Phys.org) -- Researchers have taken a step toward overcoming a key obstacle in commercializing "hyperbolic metamaterials," structures that could bring optical advances including ultrapowerful microscopes, computers and solar ...

Plasmonic device converts light into electricity

(PhysOrg.com) -- While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal ...
