Graphene-based solar cell hits record 15.6 percent efficiency

By - January 14, 2014 1 Picture
In 2012, researchers from the University of Florida reported a record efficiency of 8.6 percent for a prototype solar cell consisting of a wafer of silicon coated with a layer of graphene doped with trifluoromethanesulfonyl-amide (TFSA). Now another team is claiming a new record efficiency of 15.6 percent for a graphene-based solar cell by ditching the silicon all together. Read More

Ford's C-MAX Solar Energi Concept sports rooftop solar panels

By - January 2, 2014 11 Pictures
A plug-in hybrid car sounds like an excellent way of squaring the circle between the green cred of an electric car and the range and reliability of one that runs on petrol, but what if you live somewhere that’s a bit off the grid? Ford’s answer is its C-Max Solar Energi Concept, which makes its debut at CES next week. The car uses a combination of high-efficiency solar panels and a separate frame roofed with a Fresnel lens to concentrate sunlight on the panels to give it a proper charge without using the engine or plugging into the electrical mains.

How solar cells are taking over sea, sky and space

Solar technology has evolved beyond just your grandpa's big, bulky photovoltaic panels on the roof. Advances in flexible, hyper-efficient and nano-scale materials of late has made it possible for solar cells to begin popping up in all kinds of shapes and places you might not expect. Here's a quick rundown of some surprising spots where solar technology dwells – be sure to flip through the gallery to get a full grasp on the scale of the increasingly solar-powered landscape.

Good vibrations lead to efficient excitations in hybrid solar cells

By - November 8, 2013 2 Pictures
Increasing the efficiency of a hybrid solar cell simply by placing it near a source of ambient noise or vibration would be a boon for photovoltaics in urban areas, in the military, or on machinery or transportation. Hybrid organic/inorganic solar cells are already a tempting option over silicon because of their lower cost, but they suffer from their own drawbacks of efficiency. However, new research demonstrates that the piezoelectric qualities of the cells' inorganic layer can be used to boost the overall efficiency of hybrid systems, which is promising for wherever sound and sun are together.
