MIT's Self-Assembling PV Cells Recycle Themselves Repeatedly, Just Like Plant Cells
MIT's Test Cell Patrick Gillooly, MIT Plants are extremely efficient converters of light into energy, more or less setting the bar for researchers creating photovoltaic cells that convert sunlight into electricity. As such, researchers are constantly trying to mimic the tricks that millions of years of evolution and development have taught to plant biology. Now, a team of MIT scientists believe they've done it, creating a synthetic, self-assembling chloroplast that can be broken down and reassembled repeatedly, restoring solar cells that are damaged by the sun. While the leaves on a tree appear to be as static as the PV cells on a solar panel, they're not; sunlight is actually quite destructive, and to counter this effect leaves rapidly recycle their proteins as often as every 45 minutes when in direct summer sunlight. This rapid repair mechanism allows plants to take full advantage of the sun's bountiful energy without losing efficiency...
