We report the design and synthesis of a new organic small molecule (SM) hole transporting material (HTM) for both highly efficient solution-processed flexible inverted-type planar heterojunction perovskite solar cells(i-PSCs) and bulk heterojunction organic solar cells (BHJ IOSCs), by employing newly designed N-(4-(9H-carbazol-9-yl)phenyl)-7-(4-(bis(4-methoxyphenyl)amino)phenyl)-N-(7-(4-(bis(4-methoxyphenyl)amino)phenyl)-9,9-dioctyl-9H-fluoren-2-yl)-9,9-dioctyl-9H-fluoren-2-amine (CzPAF-TPA) as a HTM. Importantly, the SM-based device has shown significant device performance in solution-processed i-PSCs and BHJ IOSCs with power conversion efficiencies (PCEs) of 12.46% and 7.52%, respectively with good stability, which is superior to that of benchmark PEDOT:PSS. |
