A Zwitterionic Fullerene Layer Improves the Efficiency of Organic Solar Cells

Caption

UMass Amherst researchers apply a layer of zwitterionic fullerenes to allow the use of any type of metal electrode in a more efficient, lightweight and low-cost organic solar cell. The advance overcomes a decades-old barrier to improving the power conversion efficiency of organic solar cells, which had been hampered by the inherent drawbacks of metal electrodes, such as their instability and susceptibility to oxidation.
