#Engineers invent transparent coating that cools solar cells to boost efficiency Every time you stroll outside you emit energy into the universe:
Now three Stanford engineers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon.
Their invention shunts away the heat generated by a solar cell under sunlight and cools it in a way that allows it to convert more photons into electricity.
The work by Shanhui Fan, a professor of electrical engineering at Stanford, research associate Aaswath P. Raman and doctoral candidate Linxiao Zhu is described in the current issue of Proceedings of the National Academy
The hotter solar cells get, the less efficient they become at converting the photons in light into useful electricity.
The Stanford solution is based on a thin, patterned silica material laid on top of a traditional solar cell.
The material is transparent to the visible sunlight that powers solar cells, but captures and emits thermal radiation,
or heat, from infrared rays.""Solar arrays must face the sun to function, even though that heat is detrimental to efficiency,
"Fan said.""Our thermal overlay allows sunlight to pass through, preserving or even enhancing sunlight absorption,
"because it shunted thermal energy directly into the deep, cold void of space. In their new paper, the researchers applied that work to improve solar array performance
when the sun is beating down. The Stanford team tested their technology on a custom-made solar absorber--a device that mimics the properties of a solar cell without producing electricity--covered with a micron-scale pattern designed to maximize the capability to dump heat
in the form of infrared light, into space. Their experiments showed that the overlay allowed visible light to pass through to the solar cells,
but that it also cooled the underlying absorber by as much as 55 degrees Fahrenheit. For a typical crystalline silicon solar cell with an efficiency of 20 percent, 55 F of cooling would improve absolute cell efficiency by over 1 percent,
a figure that represents a significant gain in energy production. The researchers said the new transparent thermal overlays work best in dry, clear environments,
which are preferred also sites for large solar arrays. They believe they can scale things up so commercial and industrial applications are feasible
and thus tapping into increasingly efficient solar energy conversion and new pathways for CO2 reduction. Beyond this, researchers are interested in numerous other chemical reactions.
