英文摘要	The influence of the chemical: structure of conjugated polymers on the nanophase separation and device performance in fullerene-based solar cells has been widely studied, while this is, less investigated in non-fullerene solar cells. In this work, we design three conjugated polymers With-different length of side chains, and we find that the length of side chains has little influence on the quantum efficiencies of non-fullerene solar cells. As a comparison, the length of side chains has a significant effect on the quantum efficiencies of fullerene-based solar cells. This indicates that morphology of the blended thin films in non-fullerene solar, cells is rather independent of the length of the donor side chains; and the mechanism for morphology evolution in the non-fullerene system is completely different from that in the fullerene system. Our conclusion is confirmed by a variety of advanced characterization techniques. The studies reveal that in blended thin films based on the non-fullerene material the donor polymers with different side chains have a Similar coherence length of pi-pi stacking, crystal size and domain purity, giving rise-to similar internal quantum efficiency and power conversion efficiency of the solar cells.; Recruitment Program of Global Youth Experts of China; National Natural Science Foundation of China [21574138, 91233205]; Strategic Priority Research Program of the Chinese Academy of Sciences [XDB12030200]; Dutch Polymer Institute (DPI) [734, 762]; Dutch Technology Foundation STW, Netherlands Organisation for Scientific Research (NWO); Ministry of Economic Affairs; European Research Council under the European Union [339031]; Ministry of Education, Culture, and Science (NWO Gravity program) [024.001.035]; NSFC [21504006, 21534003, 51320105014]; Office of Science, Office of Basic Energy Sciences, of the U.S. Department of Energy [DE-AC02-05CH11231]; SCI(E); EI; ARTICLE; licheng1987@iccas.ac.cn; zheng.tang@iapp.de; msewma@xjtu.edu.cn; liweiwei@iccas.ac.cn; 17; 6445-6454; 49
