Description and Uses

(6,6)-PHENYL C71 BUTYRIC ACID METHYL ESTER (PC₇₁BM or C70) colloquially termed PCBM（C70）. It is classified as methanofullerenes. Because PCBM (C70) have stronger absorption in the visible range than C60,  PCBM (C70)  are often used as electron acceptors in bulk heterojunction solar cells[1].

[70]PCBM can be blended with a variety of electron donors, which include P3HT and MDMO-PPV, for the fabrication of polymeric solar cells with a high power conversion efficiency (PCE). It can also be used in the organic field effect transistor (OFET) based applications.
