Rooftop Device Generates Electricity as it Cools

Nov-13-18 An innovative new rooftop device harnesses solar power, generating electricity while also cooling the building.

Developed by a team from Stanford University, the device consists of a double-layered solar panel. The layer that faces the sun is made of the same semiconductor materials currently used on rooftops, while the bottom layer is made up of a material able to transfer the heat from the roof into space via radiative cooling.

In tests, the prototype device proved that the heat did radiate up from the bottom, though the current iteration lacked the metal foil that would have allowed it to also produce electricity. The team is now designing solar cells that not need metal liners so that the device can generate electricity and cool the building.
