Highly Efficient Organic Hole Transporting Materials for Perovskite and Organic Solar Cells with Long-Term Stability

Small molecules based on N‐atom‐linked phenylcarbazole‐fluorene as the main scaffold, end‐capped with spirobifluorene derivatives, are developed as organic hole‐transporting materials for highly efficient perovskite solar cells (PSCs) and bulk heterojunction (BHJ) inverted organic solar cells (IOSCs...

Description
Summary:Small molecules based on N‐atom‐linked phenylcarbazole‐fluorene as the main scaffold, end‐capped with spirobifluorene derivatives, are developed as organic hole‐transporting materials for highly efficient perovskite solar cells (PSCs) and bulk heterojunction (BHJ) inverted organic solar cells (IOSCs). The CzPAF‐SBF‐based devices show remarkable device performance with excellent long‐term stability in PSCs and BHJ IOSCs with a maximum PCE of 17.21% and 7.93%, respectively.
