Solar cell development inspired by moth eyes

Scientists in Japan have used moth eyes as their inspiration for a new type of solar cell.

The eyes of moths allow them to see well at night but are covered with an anti-reflective coating that helps them hide from predators.

Researchers in Japan mimicked the microstructure of moth eyes to create a new film for covering solar cells.

This can cut down on the amount of light that is reflected and helps more of the sun"s power to be captured.

"People may think this improvement is very small, but the efficiency of photovoltaics is just like fuel consumption rates of road vehicles - every little bit helps," said lead researcher Noboru Yamada, a scientist at Nagaoka University of Technology Japan.

The development is discussed in further detail in a paper in Energy Express - a bi-monthly supplement of Optics Express, which is the open-access journal published by the Optical Society.

Also recently, researchers from Northwestern University and the University of Illinois at Urbana-Champaign revealed that they had developed a camera that sees things much like the human eye does.
