Abstract

The high-temperature stability and good photoelectrochemical performance make CsPbBr3 a promising material for application as a photoanode, such as in water splitting and glucose detection. However, studies on the heat treatment of CsPbBr3 in solution and its application as a glucose oxidizer in photoanodes are still limited. This research aims to analyze the influence of heating treatment on CsPbBr3 solution and glucose concentration on the glucose oxidation performance of perovskite photoanodes in a photoelectrochemical system. First, CsPbBr3 solution was prepared using the Ligand Assisted Reprecipitation (LARP) method and heated at temperature of 110°C. Subsequently, FTO/TiO2/CsPbBr3 photoanodes were fabricated and examined using X-Ray Diffractometry (XRD) and Scanning Electron Microscopy (SEM) to determine the formed phases and morphology. The results of these tests showed that the particle size increased with heating, with a transformation from grains to rods or wires, as well as platelets and cubes due to agglomeration resulting from ligand loss during heating. The FTO/TiO2/CsPbBr3 photoanodes were then subjected to CV test, with exposure to light in a 0.5 M KOH electrolyte solution and varying glucose concentrations of 0.1 M, 0.2 M, and 0.3 M, to determine the oxidation and reduction reactions. The Cyclic Voltammetry (CV) test results showed that the FTO/TiO2/CsPbBr3 photoanodes generally exhibited high photocurrent densities in the electrolyte under illumination conditions. This was further supported by Fourier Tranform Infrared Spectroscopy (FTIR) test results, which indicated several changes in the identified chemical bonds of the electrolyte and glucose mixture post reaction on the CV test. Therefore, The FTO/TiO2/CsPbBr3 photoanode is a suitable option for glucose fuel cell.
