Thin-film solar cells could become more efficient – thanks to moths' eyes

By - May 17, 2013
Because moths need to use every little bit of light available in order to see in the dark, their eyes are highly non-reflective. This quality has been copied in a film that can be applied to solar cells, which helps keep sunlight from being reflecting off of them before it can be utilized. Now, a new moth eye-inspired film may further help solar cells become more efficient. Read More

Making solar cells with a kitchen microwave

For most people, experiments involving a home microwave typically don't go much further than inflating a marshmallow like a balloon or reheating leftovers in plasticware – both with messy results. For metallurgists though, microwaves are sometimes employed to efficiently process metals, which is how researchers at the University of Utah found themselves using a secondhand kitchen appliance in their lab. Their resourcefulness paid off recently, when the team discovered a method for creating solar cell material with just a few basic ingredients and an old microwave. Read More

Making the most of low-grade silicon for cheaper, more efficient solar panels

By - May 7, 2013
While we wait for affordable multi-junction solar cells that are pushing past the 40 percent conversion efficiency mark to make it out of the lab and onto our roofs, we have to make do with standard commercial silicon cells that currently max out at around 19 percent. A team from the University of New South Wales in Australia has found a way to improve the quality of low-grade silicon, enabling higher efficiency solar cells to be produced from cheaper, low-grade silicon.

Spectrolab claims record efficiency for new solar cell

By - April 9, 2013
Spectrolab, a Boeing subsidiary known for the manufacture of solar cells for satellites and spacecraft, has in recent years turned its attention to terrestrial solar cells to tap into the expanding alternative energy market. Now the California-based company has claimed a new solar cell efficiency record of 37.8 percent for a ground-based multi-junction cell without solar concentration. Read More

Solar-powered Volta Racer is flexible about finding sunlight

If you want to teach children about hydrogen power, you can always buy them a fuel cell-powered toy car like the H-ROVER. Should you wish to show them the merits of solar power, there are also quite a number of solar panel-equipped cars from which to choose. ToyLabs’ new Volta Racer, however, is reportedly the first toy car to feature a flexible polycrystalline silicon solar panel. Read More

Multi-use Titanium Dioxide claimed to be the next "wonder material"

By - March 21, 2013 2 Pictures
Graphene could soon be facing some competition for the unofficial title of “World’s Most Useful New Substance.” Led by Associate Professor Darren Sun, a team of scientists at Singapore’s Nanyang Technological University have spent the past five years developing a material known as Multi-use Titanium Dioxide. Their research indicates that it can be used to produce hydrogen and clean water from wastewater, double the lifespan of batteries, create antibacterial wound dressings ... and more. Read More
