Reflectivity boosts solar coating
Grow a layer of the right material on
a reflective surface and you have the makings of a coating that generates
electricity from sunlight.
The solar cell consists of a non-polymer organic material
grown on a reflective metal electrode and topped with a transparent
indium tin oxide electrode. The solar cell's efficiency is less than
one percent, but power-generating coatings could be practical at lower
efficiencies than traditional module-based solar cells.
The solar cell could lead to electricity-generating skins
for vehicles and buildings.
