CH2 Adds Something to Fullerenes



CH2 Adds Something to Fullerenes

Methylene addends in fullerene electron acceptors increase solar-cell efficiency

 Fullerene derivatives are used as electron acceptors in organic solar cells. CH2 addends can effectively raise fullerene lowest unoccupied molecular orbital (LUMO) energy levels, which leads to high open-circuit voltage (Voc). As the smallest addend, CH2 does not affect fullerene packing in the solid state, thus keeping good electron mobility for the acceptors.
