Spiro-Phenylpyrazole/Fluorene as Hole-Transporting Material for Perovskite Solar Cells

Abstract Spiro-OMeTAD with symmetric spiro-bifluorene unit has dominated the investigation of hole-transporting material (HTM) for efficient perovskite solar cells (PSCs) despite of its low intrinsic hole conductivity and instability. In this study, we designed and synthesized three asymmetric spiro...
