In this work, a non-fullerene acceptor DTY6 is designed to apply in organic solar cell (OSC) module devices. When blended with donor PM6, the DTY6-based OSCs exhibit excellent performance with power conversion efficiency (PCE) over 16% when using non-halogen solvent o-xylene. In contrast, the Y6-based OSCs show poor device performance (PCE < 11%) when processed with o-xylene. The detailed studies reveal that extremely large domains appear in the Y6-based blend film because of the excessive aggregation of Y6, which results in the lowly efficient hole transfer from Y6 to PM6 and enhanced non-radiative recombination. On the contrary, the DTY6-based film shows a more reasonable domain size, thus ensuring the efficient hole transfer from DTY6 to PM6 and low non-radiative recombination. Based on these results, non-halogen solvent o-xylene-processed large-area (active layer area 18 cm²) opaque and semi-transparent module devices based on PM6:DTY6 are fabricated by blade coating, and outstanding PCEs of 14.4% and 11.6% are obtained.

在这项工作中，非富勒烯受体DTY6被设计用于有机太阳能电池（OSC）模块设备。当与供体PM6混合时，基于DTY6的OSC在使用非卤素溶剂邻二甲苯时表现出卓越的性能，功率转换效率（PCE）超过16％。相反，当用邻二甲苯处理时，基于Y6的OSC显示出较差的器件性能（PCE <11％）。详细的研究表明，由于Y6的过度聚集，在Y6基混合膜中出现了非常大的畴，这导致从Y6到PM6的空穴转移效率低下，并且增强了非辐射重组。相反，基于DTY6的薄膜显示出更合理的畴尺寸，从而确保了从DTY6到PM6的有效空穴转移和低非辐射复合。根据这些结果，²）通过刮刀涂覆制造基于PM6：DTY6的不透明和半透明的模块器件，并且获得了14.4％和11.6％的优异PCE。
