Judicious Molecular Design of 5H‑Dithieno[3,2‑b:2′,3′‑d]Pyran‐based Hole‐Transporting Materials for Highly Efficient and Stable Perovskite Solar Cells

Abstract The structural modification of hole‐transporting materials (HTMs) is an effective strategy for enhancing photovoltaic performance in perovskite solar cells (PSCs). Herein, a series of dithienopyran (DTP)‐based HTMs (Me‐H, Ph‐H, CF3‐H, CF3‐mF, and CF3‐oF) is designed and synthesized by subst...
