摘      要：A 54 -electron fullerene acceptor,indene bis-methano[60]fullerene(IBMF),having one indene and two sterically compact CH2 groups was *** 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 *** superior performance of IBMF solar cells originates from higher mobility of IBMF and better morphology for IBMF/P3HT blend films.
