Printed Flexible Solar Cells Provide Embedded Renewable Power

May 12, 2008 6:43 am | Blogs | Comments

With the cost of energy approaching the insane, new and improved methods of creating better and more easily deployable solar power cells are very welcome. This advance in manufacture by Konarka Technologies promises to deliver cheaper power cells in large quantities. I hope they can commercialize the technology to the point we can use solar as a tricke-charge backup in every powered application exposed to the sun.
