摘　　要：Chloroform is a common and excellent solvent for preparing high-efficient organic solar cells(OSCs),however,it is toxic and poisonable chemical.In comparisons,deuterated chloroform(DC)is less toxic and costly,and particularly,it is non-poisonable chemical.In this paper,we use DC to replace ultra-dry chloroform(UC)as the processing solvent for preparation of active layers of organic solar cells.First,we selected PM6:BTP-e C9 as the basic binary and counted 100 solar cells'data,from which comparable device performance were obtained with use of DC and UC.Interestingly,DC showed better reproducibility,superior storage under a nitrogen atmosphere and a little better performance than UC.Both DC and UC gave rise of comparable hole and electron mobilities and similar charge recombination losses.Second,we based PM6:Y6 and D18-Cl:Y6 as the binaries and similar effects were obtained from both UC and DC when counting 30 devices for each binary.Third,the universality of the use of DC for preparing highefficient OSCs were again checked with several binary and ternary systems.In all,this study demonstrate that DC can replace UC for use in the field of OSCs.
