At the heart of the technology are solar panels made from black metal that has been treated with femtosecond lasers. A femtosecond is an extraordinarily short unit of time, equal to one quadrillionth of a second. Pulses from these ultrafast lasers can precisely alter a material's surface, creating microscopic structures that dramatically change how it interacts with light and water.

Neat

And it's very easy to make, you just need to ask Finland to get black metal

Yeah, but the environmental cost of the corpse paint hasn't been well studied
