A New Methodology for Film Preparation: Comparison Between Doctor Blading and Airbrushing Methods on Scaffold Materials

This paper explores the potential of the airbrushing method as a novel and cost-effective method for producing uniform titanium dioxide (TiO2) films, crucial for enhancing the efficiency of dye-sensitized solar cells. The techniques performed were SEM and EDS images, OCP curves, photochronoamperometry, j-V curves, and impedance spectroscopy. Comparative analysis with the doctor blade methodology has noted a higher uniformity compared to the AB method, with the ability to improve the charge transportation and PCE (1.987%) and reduce the recombination process in the TiO2/electrolyte interface (ԏe = 0.012 s). Insights from EIS spectroscopy and intensity-modulated spectroscopy offer mechanistic elucidations of the enhanced performance. Overall, this study highlights airbrushing as a promising approach for advancing the development of high-performance solar energy systems.
