| Description | Dye-sensitized solar cells are gaining interest in the aerospace industry, extending their applications from solar-powered drones to origami-style space-based solar power stations due to their flexibility, light weightiness, and transparency. The major issue with its widespread commercial use is the employment of expensive Pt-based counter electrodes. In this study, an attempt has been made to replace the Pt with Polyaniline (PANI)/Molybdenum sulfide $(MoS_{2}$) nanocomposite. The nanocomposites i.e., PANI-0.5wt% $MoS_{2}$, $PANI-2wt%MoS_{2}$, $PANI-5wt%MoS_{2}$, and $PANI-7wt%MoS_{2}$and $PANI-9wt%MoS_{2}$, have been synthesized and compared with standard Pt-based CE. Scanning electron microscopy, transmission electron microscopy, and X-ray diffraction methods have been utilized to study both surface morphology and structural composition. Fourier transform infrared has also been used to identify redox-active functionalities. Electron impedance spectroscopy and cyclic voltammetry have been employed to study electron transfer and catalytic activity. Finally, I-V testing has been conducted using a sun simulator. A maximum efficiency of 8.12% has been observed with 7wt% $MoS_{2}$ in the PANI matrix at 6 µm thickness, which is 2.65% higher compared to standard Pt-based CE (7.91%). This is due to high electronic conduction with the addition of $MoS_{2}$, improved catalytic activity, and the high surface area of the PANI nano-rods. |
