Qiang Fu et al.

Summary: Optimizing the molecular packing and orientation of dopant-free hole-transport materials (HTMs) is an effective strategy for achieving high-performance perovskite solar cells (PSCs). By regulating the donor building blocks and using a large core unit, we successfully demonstrated tunable molecular packing and orientation of polymers. The developed PC-DPP conjugated polymer with a preferred face-on orientation showed enlarged hole mobility and improved efficiency in PSCs compared to the control PBDT-DPP polymer with a preferred edge-on orientation. This work opens up possibilities for developing dopant-free HTMs.
