Print-On Polymer Multiplies Solar Output

PORTLAND, Ore. — Scientists have demonstrated a doubling of the number of electrons produced by carbon-based photovoltaic polymer potentially doubling the efficiency of any solar cell. The process called “singlet fission” produces “identical twin” electrons from a single photon, instead of the normal one, dramatically boosting the theoretical maximum output of solar cells. Instead of
