ABSTRACT
The article focuses on a research work in the U.S. that has improved the efficiency of a "spray-on" polymer-based solar cell which moves it closer to practical use. The North Carolina scientists have hit six per cent efficiency in buckyball-doped polymer solar cells. Starting with a flexible polycarbonate substrate, Wake Forest University sputters on indium tin oxide (ITO), spins on the active layer, then tops it off by depositing a thin metal contact. The electrons leave through the metal and the holes leave through the ITO. INSET: Increasing efficiency through a novel heat treatment.
