Thienothiophene‐Assisted Property Optimization for Dopant‐Free π‐Conjugation Polymeric Hole Transport Material Achieving Over 23% Efficiency in Perovskite Solar Cells

Hole transport materials (HTMs) play essential roles in achieving high photovoltaic performance and long‐term stability in the n–i–p structure of perovskite solar cell (PSC) devices. Recently, dopant‐free polymeric materials as HTMs in PSCs have attracted considerable attention owing to high carrier...
