Solar Cell – Cooling Uses Space as a Heat Sink

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 http://news.stanford.edu/news/2015/september/thermal-overlay-solar-092115.html/
