Moth eye-inspired material boosts efficiency of solar cells

By - January 23, 2011 2 Pictures
In order for a solar cell to be as efficient as possible, the last thing it should be is reflective – after all, light should be getting absorbed by it, not being bounced off. With that in mind, a few years ago a group of Japanese scientists set out to create an antireflective film coating for use on solar cells. What they ended up creating utilizes the same principles that are at work in one of nature’s least reflective surfaces: moth’s eyes. Read More

Highly efficient light extraction from semiconductors promises better LEDs

By - September 1, 2010 2 Pictures
One of the biggest challenges in creating a better light-emitting diode (LED) is the search for a way to efficiently extract the light generated in the semiconductor device into the surrounding air, while avoiding the internal light reflection that is cause for a considerable waste of energy. A team of Japanese researchers have recently managed to achieve just that, in what is believed to be a huge step toward significantly more energy-efficient LEDs. Read More

Scientists say goodbye to screen glare

By - May 5, 2010 1 Picture
If you have a cell phone or laptop or large screen TV, you’ll understand how annoying it is when sunlight glare renders your screen illegible. It’s even dangerous if that glare hits your dashboard and you can’t see how fast you're going. And for people who wear spectacles, glare off the lenses can be debilitating. But a new nanocoating developed by scientists at the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, have developed a perfectly non-reflecting material for use on displays and through eyeglasses. The hybrid coating has further advantages: the components are scratch-proof and easy to clean. And where did the inspiration come from … would you believe moths? Read More

Tests on reducing glare and fingerprints from touch screen devices

By - August 27, 2009 1 Picture
Big touch screens, like those used on smart phones and portable media devices, are great … unless the sun is out. Then the glare can be a killer, rendering some devices next to useless. Scientists have developed a test for analyzing reflection-resistant coatings to make using touch screen devices easier. The research also includes defining a better smudge-resistant coating to deter ugly fingerprints and scratches from screens and surfaces. Read More
