Abstract
4-Amino-2,2,6,6-tetramethylpiperidine-1-oxyl (4-Amino-TEMPO; 4AT), has been used as a photo-catalyst to boost photo-catalytic activity, are a promising approach for improving the efficiency of fiber-shaped dye-sensitized solar cells (FDSSCs) and fiber-shaped organic light-emitting diodes (FOLEDs). Herein, one of the 4AT, 4-p-toluenesulfonamide-TEMPO (ATpTS) was successfully synthesized by using a dropwise method. The synthesized ATpTS showed an extraordinary photo-catalytic effect and significantly enhanced performance compared to the pristine-based active layer for both solid-state electrolytes of the FDSSCs (SS-FDSSCs) and FOLEDs. Briefly, a power conversion efficiency increment of 22.8% is recorded for the ATpTS-enhanced SS-FDSSCs; whereas an external quantum efficiency increment of 45.4% is achieved for the ATpTS-enhanced FOLEDs.
