Collecting the Electrons on n-Doped Fullerene C60 Transparent Conductors for All-Vacuum-Deposited Small-Molecule Organic Solar Cells.

n‐Doped C60 is reported as a new electrode material for indium‐tin‐oxide‐free organic solar cells. All layers from the bottom to top electrode are prepared in one step in a vacuum chamber. The organic solar cells based on the n‐C60 electrodes assisted by a semitransparent metal grid exhibit efficiencies as high as 2.9%. [ABSTRACT FROM AUTHOR]
