title: Synthesis and photovoltaic properties of acceptor materials based on the dimerization of fullerene C60 for use in efficient polymer solar cells.
abstract: We demonstrate that dimeric fullerene derivatives work as an excellent n-type material for polymer solar cells in combination with P3HT or PTB7, showing the best PCE of 3.3% or 6.1%, respectively. The device performance was influenced by the position of the two C60 moieties linked together.
