In the article \u00abSelf-assembled PCBM bilayers on graphene and HOPG examined by AFM and STM\u201d Yanlong Li, Chuanhui Chen, John Burton, Kyungwha Park, James R Heflin and Chenggang Tao demonstrate that PCBM molecules self-assemble into bilayer structures on graphene and HOPG substrates. They used Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM), and analyzed the observed morphology by comparison to molecular models.*<\/p>\n

The AFM measurements were carried out in a dark environment. NanoWorld\u2122 Pointprobe\u00ae NCST<\/a> AFM probes were used in soft tapping mode and simultaneous height and phase images were acquired and reproduced across multiple samples.*<\/p>\n

The results of this study shed light on improvement of the energy efficiency in solar cells containing graphene and organic molecules, by increasing the donor\u2013acceptor interface area and could provide valuable insight into fabrication of new hybrid, ordered structures for applications to organic solar cells.*<\/p>\n
