Functional Thiophene-Based Nanomaterials for Organic Photovoltaic


Oligo- and polythiophenes represent an important class of compounds in the field of organic materials and have successfully been used as active components in organic solar cells (OSC). Their main strength lies in their excellent optoelectronic properties and as well in their good charge transport properties, which are crucial for most applications.[1]

On the basis of oligothiophenes, we are currently synthesizing and investigating novel organic semiconductors, which are applied in various types of organic solar cells.[2] In this respect, acceptor-substituted oligothiophenes have been further developed and tuned with respect to their electrooptical and self-organization properties. Efficiencies in vacuum-processed small molecule organic solar cells could be increased to record values of 6.9% for single junction cells. X-ray structure analyses guide the understanding how intermolecular interactions in the bulk correlate with device performance.[3]
