Solar Cell Cooling Uses Space as a Heat Sink

Solar Cell Cooling Uses Space as a  Heat Sink
Sep-23-15
A new silicon coating for solar cells uses space itself as a giant heat sink—transferring excess heat from the cells for better efficiency.

A long-standing problem with solar cell is that the hotter they become, the less efficient they are—a tricky problem since the cells are meant to be placed in direct sunlight. A team from Stanford University aims to address that problem with a transparent silicon coating designed to lay over the cells, where it collects the excess heat and then radiates it out as electromagnetic waves. The coating will not interfere with the cells’ light-collecting, and could also be scaled up for use on other objects that need heat dispersal, such as passive cooling on cars.
