Radiative cooling tech for vertical solar panels

Developed by a US-Saudi research group, the novel technique employs two 45-degree inclined mirrors on the two sides of a PV module. On the back side, a spectral selective reflector enables the thermal radiation to be directed to the sky while preventing the back of a module from heating up by the scattered sunlight.
