Recyclable solar cells created using trees

Researchers at Georgia Institute of Technology and Purdue University have developed new solar cells based on natural substances derived from plants, including trees. The organic solar cells have an efficiency of 2.7 percent – a new high for cells on substrates derived from renewable raw materials – and can be easily recycled. 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"

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

Empa claims new world record for solar cell efficiency

Scientists based at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have set a new efficiency record for thin-film copper indium gallium (di)selenid (or CIGS) based solar cells on flexible polymer foils, reaching an efficiency of 20.4 percent. This is an increase from a previous record of 18.7 percent set by the team back in 2011. Read More

Stanford University researchers create peel-and-stick solar cells

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.Read More

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

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

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.Read More
