A star-shaped cyclopentadithiophene-based dopant-free hole-transport material for high-performance perovskite solar cells
A new cyclopentadithiophene (CPDT)-based organic small molecule serves as an efficient dopant-free hole transport material (HTM) for perovskite solar cells (PSCs). Upon incorporation of two carbazole groups, the resulting CPDT-based HTM (C-CPDT) shows an impressive power conversion efficiency (PCE)...

Zusammenfassung: | A new cyclopentadithiophene (CPDT)-based organic small molecule serves as an efficient dopant-free hole transport material (HTM) for perovskite solar cells (PSCs). Upon incorporation of two carbazole groups, the resulting CPDT-based HTM (C-CPDT) shows an impressive power conversion efficiency (PCE) of 19.68% with better stability compared with those of spiro-OMeTAD.
Devices based on star-shaped cyclopentadithiophene,
C-CPDT
, as a dopant-free HTM exhibit a promising efficiency of 19.68% and excellent long-term stability. |
