Solar cells are not easy to build, but a new technology from Notre Dame could, someday, change that. It involves a nanoparticle paste made from t-butanol, water, cadmium sulfide and titanium dioxide. Here, you watch the process of constructing a solar cell this way and see why it could be easier and cheaper than current options.
