Caltech’s new solar cells

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.

In the spring of 2005, I graduated from the University of British Columbia with a degree in International Relations and a general focus in the area of environmental politics. In the fall of 2005, I began reading for an M.Phil in IR at Wadham College, Oxford. Outside school, I am very interested in photography, writing, and the outdoors. I am writing this blog to keep in touch with friends and family around the world, provide a more personal view of graduate student life in Oxford, and pass on some lessons I've learned here.
