	1	The impact of fluorination on both donor polymer and non-fullerene acceptor:The more fluorine,the merrier显示文摘Fluorination of the donor polymer or non-fullerene acceptor (NFA) in an organic photovoltaic device is an effective method to improve device efficiency.Although there have been many studies on donor polymer fluorination,blends containing both a fluorinated donor and fluorinated NFA have rarely been reported.In this study,we use two donor polymers (4'-FT-HTAZ and 4'-FT-FTAZ) and two NFAs (ITIC-Th and ITIC-Th1) with different amounts of fluorine (from 2F to 6F) to investigate how the degree of fluorination in a blend impacts device performance.We find that fluorinating the NFA leads to a higher short-circuit current density (Jsc) and fill factor (FF),however,the open-circuit voltage (Voc) is decreased due to a depressed lowest unoccupied molecular orbital (LUMO) level.Adding additional fluorine to the donor polymer does not have a large effect on the Jsc or FF,but it does lead to an improved Voc.By fluorinating the NFA and having more fluorine on the donor polymer,we obtain both a high Jsc and Voc simultaneously,leading to a power conversion efficiency over 10% in the case of 4'-FT-FTAZ:ITIC-Th1,which has the most amount of fluorine (6F).
