  31. The band gap and reduction potential of [70]PCBM are similar to those of C60-PCBM,[25] hence the oxidation potential of is [70]PCBM must also be similar to that of C60-PCBM (Eox=+1.08 V vs. Fc/Fc+),[23] which is nearly 1 V higher than that of spiro-MeOTAD (Eox=+0.118 V vs. Fc/Fc+).[22] This allows efficient electron transfer from photoexcited [70]PCBM to spiro-MeOTAD.

  33. The absorption of the radical anion of [70]PCBM is likely to be obscured by the radical cation absorption of spiro-MeOTAD. This is also the case for MDMO-PPV:[70]PCBM blends.[25].
