Abstract
Hole transporting material (HTM) highly affect efficiency and stability of perovskite solar cells (PSCs). Therefore, suitable HTMs should be designed to effectively extract and transfer holes in PSC devices. Herein, several HTMs were engineered composed of Spiro[fluorene-9,9′-xanthene] (SFX) core functionalized with natural twenty-one amino acids at the ortho, meta, and
