‘Electrode Barrier’ Broken for Organic Solar Cells
AMHERST, Mass., Sept. 19, 2014 — A new organic solar cell has broken the “electrode barrier” known to hamper efforts to enhance efficiency.
A team from the University of Massachusetts Amherst developed the cell, which can use virtually any metal as the electrode. Many common metal electrodes can obstruct the power conversion efficiency of organic solar cells, as they are typically unstable and susceptible to oxidation.
