Polymer solar cells that use self-assembled-monolayer-modified ZnO/Metals as cathodes
A simple solution-deposition method is developed to fabricate polymer solar cells that comprise a SAM-modified ZnO/metal bilayer cathode. The contact properties between the ZnO and metal can be enhanced by interfacial modification with a series of carboxylic acid-based dipolar SAMs. This finding provides a new strategy for very effective contact engineering in organic optoelectronic devices.
