20_10/2010Bulk Heterojunctions: Ultrafast Hole-Transfer Dynamics in Polymer/PCBM Bulk Heterojunctions (Adv. Funct. Mater. 10/2010)

The active layer of the currently most efficient plastic photovoltaic cells is a blend of polymer and methanofullerene molecules. In their article on page 1653, M. S. Pshenichnikov et al. show that hole transfer upon methanofullerene excitation operates simultaneously with electron transfer as the charge generation process in plastic photovoltaics, at a staggering timescale of 30 fs.
