Interlayer for Modified Cathode in Highly Efficient Inverted ITO-free Organic Solar Cells

Adv Mater. 2012 Jan 24;24(4):554-8. doi: 10.1002/adma.201104579.


Inverted polymer solar cells with a bottom metal cathode modified by a conjugated polymer interlayer show considerable improvement of photocurrent and fill factor, which is due to hole blocking at the interlayer, and a modified surface energy which affects the nanostructure in the TQ1/[70]PCBM blend.
