Major infrared breakthrough could lead to solar power at night

The sun’s enormous energy may soon be harnessed in the dark of night following a significant advance in thermal capture technology. Solar radiation heats the earth’s crust significantly during daylight hours, but that energy is lost into the coldness of space when the sun goes down. Now, researchers within the School of Photovoltaic and Renewable Energy […]
