Comparing energy conversion of plants and solar cells
Scientists now have a way to more accurately compare how efficiently plants and photovoltaic, or solar, cells convert sunlight into energy, thanks to findings by a research consortium that included a U.S. ...
A single polymer can be used to fabricate both thin-film transistors and solar cells
Polymers are the material of choice for making thin-film transistors and solar cells. They are also potentially suitable for manufacture using economical, high-throughput techniques, such as roll-to-roll and inkjet printing ...
Solar power could get boost from new light absorption design
Solar power may be on the rise, but solar cells are only as efficient as the amount of sunlight they collect. Under the direction of a new professor at Northwestern University's McCormick School of Engineering and Applied ...
'Oscar Madison' approach to solar cells may outshine 'Felix Unger' design
Sometimes neatness may not be necessary. Researchers have demonstrated that a tangled coating of randomly positioned nanowires can increase solar cell efficiency by absorbing more light.
Nano-LEDs emit full visible spectrum of light
New solar product captures up to 95 percent of light energy
Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available ...
