1 August 2014 - A new material, combined with a cheap tracking system, could unleash the promise of concentrated solar power.
A material with optical properties that change to help it capture more incoming sunlight could cut the cost of solar power in half, according to Glint Photonics, a startup recently funded by the Advanced Research Projects Agency for Energy (ARPA-E).
Glint’s adaptive material greatly reduces the cost of a tracking system used in some types of solar power. It changes its reflectivity in response to heat from concentrated sunlight in a way that makes it possible to capture light coming in at different angles throughout the day.
It’s well known that focusing sunlight makes it possible to use smaller, cheaper solar cells. read more>>>
