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

Triple-junction solar cell design could break 50 percent conversion barrier

By - January 16, 2013 2 Pictures
The current world record for triple-junction solar cell efficiency is 44 percent, but a collaboration between the U.S. Naval Research Laboratory (NRL), the Imperial College of London, and MicroLink Devices Inc. has led to a multi-junction photovoltaic cell design that could break the 50 percent conversion efficiency barrier under concentrated solar illumination.

Stanford University researchers create peel-and-stick solar cells

By - December 21, 2012 3 Pictures
Traditionally, thin-film solar cells are made with rigid glass substrates, limiting their potential applications. Flexible versions do exist, although they require special production techniques and/or materials. Now, however, scientists from Stanford University have created thin, flexible solar cells that are made from standard materials – and they can applied to just about any surface, like a sticker.

Nano-sandwich material claimed to boost solar cell efficiency by 175 percent

By - December 7, 2012 3 Pictures
One of the main reasons that solar cells aren’t more efficient at converting sunlight into electricity is because much of that sunlight is reflected off the cell, or can’t be fully absorbed by it. A new sandwich-like material created by researchers at Princeton University, however, is claimed to dramatically address that problem – by minimizing reflection and increasing absorption, it reportedly boosts the efficiency of organic solar cells by 175 percent.

electree+ bonsai solar charger combines form and function

By - November 27, 2012 8 Pictures
Sitting somewhere between the "solar trees" erected on parking garages at the University of California in San Diego (UCSD) and the nanotrees developed on the same campus, the electree+ is a sculptural bonsai tree with 27 solar cells for "leaves." The tree's branches can be adjusted to catch the rays just right, and its internal battery will store enough electricity to charge an iPhone5 nine times over, a Galaxy S3 seven times, or an iPad 2 twice.
