The brown and yellow parts of its body have the ability to absorb solar radiation, and a pigment in the yellow area is known to play a role in photosynthesis.
Full article: http://news.discovery.com/tech/hornet-has-natural-solar-cells-in-its-body.htmlThey found that the brown shell is made of an array of grooves that split sunlight into diverging beams. The yellow parts has small oval-shaped protrusions, each with one or two “pinhole” depressions. The yellow sections also contain the pigment xanthopterin tightly packed in granules. Xanthopterin has the ability to change light into electrical energy. So basically the shell is trapping sunlight and the xanthopterin is converting it to energy.
The team also modeled the structure of the hornet's body by building a solar cell that used xanthopterin as the light-harvesting molecule. But because they were unable to precisely model the complex nanostructures found in the shell, the solar cell had a low conversion rate. For their next work, they'll be looking at how to replicate the intricate grooves and pinhole depressions. It could happen that one day, we have solar cells inspired by the Oriental hornet.
Nature has a way of being extremely efficient and ingenious. If we can mimic the sunlight diverter design, maybe we can use that idea to improve solar panel technology.
