(6,6)-PHENYL C71 BUTYRIC ACID METHYL ESTER, 99% (MIXTURE OF ISOMERS) Usage And Synthesis

Applications

PC70BM is a fullerene electron acceptor commonly used in the most efficient organic photovoltaic devices. The non-symmetrical C70 cage of PC70BM enables energetic transitions that are forbidden in C60, improving the absorption characteristics over PC60BM for the visible range of the solar spectrum. This allows increased photon harvesting, and a potentially higher photocurrent for devices using PC70BM rather than PC60BM. The 95% purity PC70BM is recommended for general applications, and has produced power conversion efficiencies of over 9% in our own laboratories when mixed with a low bandgap polymeric donor, while the 99% PC70BM is recommended where ultimate performance is required.
The energy levels and good electron mobility of PC70BM enable it to be used as an electron transport layer in perovskite solar cells. In our laboratories, we have achieved a PCE approaching 12% using PC70BM in CH3NH3PbI3-xClx perovskite solar cells.
