What if making a solar cell was as easy as printing a newspaper? What if it was flexible, light and above all, cheap? The current photovoltaic (PV) market, dominated by expensive and fragile silicon, would be revolutionized. These are the lofty ambitions of a growing number of scientists in companies and universities worldwide who are developing organic photovoltaics: solar cells that are made from carbon-based molecules."
