Supramolecular Approaches to Nanoscale Morphological Control in Organic Solar Cells

Int J Mol Sci. 2015 Jun 11;16(6):13381-406. doi: 10.3390/ijms160613381.


Having recently surpassed 10% efficiency, solar cells based on organic molecules are poised to become a viable low-cost clean energy source with the added advantages of mechanical flexibility and light weight. The best-performing organic solar cells rely on a nanostructured active layer morphology consisting of a complex organization of electron donating and electron accepting molecules. Although much progress has been made in designing new donor and acceptor molecules, rational control over active layer morphology remains a central challenge. Long-term device stability is another important consideration that needs to be addressed. This review highlights supramolecular strategies for generating highly stable nanostructured organic photovoltaic active materials by design.

Keywords: device stability; morphology; nanowires; organic semiconductors; self-assembly; solar cells; supramolecular interactions.
