Our work reporting the three dimensional morphology in PBDB-T:IT-M non-fullerene solar cells is accepted in Solar RRL. We built up the vertical and lateral morphology in the thin photovoltaic films by a comprehesive approach of GIWAXS, GISAXS and XPS (with etching ability) investigation, and is a collaboration with Prof. Jianhui Hou and Miss Sunsun Li (ICCAS, China), Prof. Trystan Watson and James McGettrick (Sweason University, UK), Dr. Zhe Li (Cardiff University, UK), Dr. Andrew Pearson (Cambridge University), and Prof. David Lidzey (University of Sheffield, UK). Thanks for all your contribution.
