摘　　要：A 54 -electron fullerene acceptor,indene bis-methano[60]fullerene(IBMF),having one indene and two sterically compact CH2 groups was developed.Using P3HT as donor,IBMF solar cells gave a PCE of 5.18%,which is higher than that for solar cells based on IC60TA,which has three indenes.The superior performance of IBMF solar cells originates from higher mobility of IBMF and better morphology for IBMF/P3HT blend films.A 54π-electron fullerene acceptor, indene bis-methano [60] fullerene （IBMF）, having one indene and two sterically compact CH2 groups was developed.
