The IPX fullerenes give significantly increased device performance compared to PCBM in both polymer and perovskite OPV.
In P3HT:fullerene solar cells, the efficiency can be increased by 10-15% compared to PCBM, because the open circuit voltage is raised by 50 mV. Two of these IPX derivatives are available from stock: IPB and IPH. The price for these two compounds is the same. Others can be made upon request.
