Abstract

Disclosed is a fabrication method for constructing low-cost, morphologically stable, highly ordered, and crystalized layered organic solar cells. The method implements self-assembled molecular monolayers as building blocks (a bottom up strategy) to fabricate a device. This approach enables the creation of a layered material with desired morphology in a controlled way. In such geometry, optoelectronic and transport properties can be controlled by metal atom inclusions into the molecular monolayers, which presents a range of options in creating photo-sensitive molecular building blocks to cover a wide range of the solar spectra from IR to visible to UV.
