Researchers at a California Institute of Technology have developed a flexible solar panel that uses only 1 percent of the material used in conventional panels. Describes features a digital edition of the journal Nature Materials. "Unlike other solar panel designs, the new high efficiency achieved in converting light into energy. Possible uses for this panel as light and efficient could range from sunroofs to devices placed in cars to clothing.
The researchers, led by Harry Atwater, achieved these high levels of absorption of light using much less amount of semiconductor material used in your device, small rods of silicon the size of micrometers. The incoming light bounces many times between the sticks on the device until it is absorbed.
To ensure that the light is directed more efficiently, the scientists used small nanoparticles of aluminum reflectors located between the rods. The overall result is that up to 85 percent of usable sunlight that reaches the device is absorbed by it. This innovative design
have fewer resources to reducing the cost of this technology more affordable producciónHaciendo alternative. That being the sun for everyone, we all benefit from clean energy that can give us warmth.
