General description

[6,6]-Phenyl C71 butyric acid methyl ester, mixture of isomers ([70]PCBM), is a high fullerene analog to [60]PCBM, which has an enhanced absorption of light in the visible region. It can be used in the development of electrochemical devices with a high current density.

Application

[70]PCBM and PCDTBT can be used as an acceptor and donor based fullerene derivative, which can be used in the fabrication of organic photovoltaics. It may be used with P3HT as an electron transporting material for the fabrication of solar cells with higher power efficiency.
[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.

Since the first publication in 1995 describing a bulk heterojunction photodiode incorporating a methanofullerene, significant progress has been made in improving device performance and the scope of device research has broadened widely.

The field of organic electronics has emerged as the next-generation technology potentially enabling ultra-thin, large-area, and/or flexible devices, consisting of organic field-effect transistors (OFETs), organic light-emitting diodes (OLEDs), and organic photovoltaics (OPVs).

PCBM-based n-type semiconductors - Find p- and n-type organic semiconductors available from Sigma-Aldrich with PCBM library & properties.

The emerging organic photovoltaic (OPV) technology is very promising for low-cost solar energy production. OPV devices can be produced using high-throughput, large-volume printing methods on lightweight and flexible plastic substrates, making them easy to deploy and use in innovative ways.
