Caltech’s new solar cells


in Geek stuff, Science, The environment

In an announcement that is exciting, if accurate, researchers from Caltech claim they have developed cells that can capture 85 percent of total collectible sunlight using only a fraction of the silicon required for conventional cells. The cells are 98% transparent plastic, with just 2% of their volume comprised of silicon.

For now, they have only built tiny ones. If the approach can be effectively scaled up, it could help cut the capital cost for solar photovoltaic facilities.
