WIN is pleased to congratulate first author, Nancy Eisenmenger, whose paper with advisor Michael Chabinyc (UCSB) on the "Effect of Bridging Atom Identity on the Morphological Behavior of Solution-Processed Small Molecule Bulk Heterojunction Photovoltaics" was one of the most downloaded papers in the journal "Chemistry of Materials" for the last quarter, April-June 2013. Small alterations in the chemistry of cyclopentadithiophene units in an electron donor material were shown to leave electronical and optical properties unchanged, but affect the melting points and the extent of crystalline domains when mixed with the electron acceptor, PCBM. This may affect our ability to make effective all-organic solar cells.
