- Novel organic dye sensitizers containing fluorenyl and biphenyl moieties for solar cells
-
Three novel triarylamine dyes (AFL1–AFL3) containing fluorenyl and the biphenyl moieties have been designed and synthesized for application in dye-sensitized solar cells. The light-harvesting capabilities and photovoltaic performance of these dyes were investigated systematically through comparison of different π-bridges. The dye with a furan linker exhibited a higher open-circuit voltage (VOC) and monochromatic incident photon-to-current conversion efficiency (IPCE) compared to thiophene and benzene linker. Thus, AFL3 containing a furan linker exhibited the maximum overall conversion efficiency of 5.81% (VOC?=?760?mV,?JSC?=?11.36?mA?cm?2and ff?=?0.68) under standard global AM 1.5 G solar condition.

-
Two hole transport materials, N-([1,1'-biphenyl]-4-yl)-9,9-dimethyl-N-(4-(naphtho[2,1-b]benzofuran-6-yl)phenyl)-9H-fluoren-2-amine (DFA) and N-(9,9-dimethyl-9H-fluoren-2-yl)-9,9-dimethyl-7-(naphtho[2,1-b]benzofuran-6-yl)-N-phenyl-9H-fluoren-2-amine (TFA) were designed, synthesized and fully characterized. The photophysical and thermal properties of these two compounds were investigated by UV–vis absorption spectra, photoluminescence spectra, thermogravimetric analysis (TGA) and differential scanning calorimetry analysis (DSC), which indicated that DFA and TFA would be efficient hole transport materials due to their proper HOMO energy levels and excellent thermal stability. Then, green OLEDs with DFA and TFA as hole transport layer, respectively, were fabricated, NPB-based OLEDs was also prepared for comparison. It turned out that DFA- and TFA-based devices exhibited higher efficiencies than that of NPB-based device, and TFA-based device showed the best performances with current efficiency, power efficiency and external quantum efficiency of 41.68 cd/A, 32.04 lm/W and 12.04%, respectively.
