Hot Solar Cells: 10 Breakthrough Technologies 2017

By converting heat to focused beams of light, a new solar device could create cheap and continuous power. [Read More]

Summary… * Machine-Made

The trick is to first turn sunlight into heat and then convert it back into light, but now focused within the spectrum that solar cells can use.
Standard silicon solar cells mainly capture the visual light from violet to red.
Hot Solar Cells Breakthrough A solar power device that could theoretically double the efficiency of conventional solar cells.
It essentially acts as a light funnel above the solar cells.
Concentrated light from a solar simulator shines through the window of a vacuum chamber, where it reaches the solar thermophotovoltaic device and generates electricity.

Opinion… * Man-Made
