AB  - We investigate the internal quantum efficiencies (IQEs) of high efficiency 
      poly-3-hexylthiophene:[6,6]-phenyl-C(61)-butyric acid methyl ester (P3HT:PCBM) 
      solar cells and find them to be lower at wavelengths where the PCBM absorbs. 
      Because the exciton diffusion length in PCBM is too small, excitons generated in 
      PCBM decay before reaching the donor-acceptor interface. This result has 
      implications for most state of the art organic solar cells, since all of the most 
      efficient devices use fullerenes as electron acceptors.
