Will Nanoantennas replace PV Solar Cells?
Tuesday, August 12th, 2008Researchers at the DoE’s Idoho National Laboratory have come up with an inexpensive way to use “nanoantennas” to collect heat energy produced by the sun and other sources. Flexible plastic sheets containing the nanoantennas could then be mass produced to creat flexible lightweight “skins” that could power everything from iPods to hybrid […]

Laser textured solar cells will reflect less light and be more efficient
Wednesday, August 6th, 2008A University of Virginia team has been working on creating tiny nanoscale surface textures on solar cells that may reduce energy loss to less than 1 percent, compared to 30 percent or so that current solar cell non-reflecting coatings provide. By using lasers to create ‘nanospikes’ on the surface of the cell, the added […]

Science Daily: MIT researchers develop new way to store solar power
Saturday, August 2nd, 2008One of the drawbacks of solar cells is that they only work when the sun is shining, and current methods to store the power produced by the cells for non-sunny periods are extremely expensive and very inefficient. Now, MIT researchers are claiming a breakthrough in power storage that will allow for inexpensive and efficient […]

MIT researchers develop new solar power windows
Friday, July 11th, 2008In a press release, MIT researchers have reported that they have developed solar power concentrators that can be used to turn windows into solar panels. Their new technique paints the window glass with a mixture of two or more tranparent organic dyes that absorbs and transports the light to solar cells that are positioned around […]
