The electrochemical performance of Lanthanum Indium Sulphide photoactive electrode in a simple yet efficacious photoelectrochemical cell

Abstract

The most effective way to boost electrochemical efficiency is to design nanostructures that fully exploit the advantages of all metals and create an interfacial impact between structures. In this study, diethyl dithiocarbamate compound is used to produce an elongated with flowery flakes In:SnO2/La3InS6 structure. The morphological, crystalline, and opto-electrical properties of the substance were examined. According to UV–visible analysis, the direct optical band gap was 4.2 eV. The core level of La3d, In3d and S2p was revealed by X-ray photoelectron spectroscopy. Electrical testing of a photoelectrochemical cell's transparent photoactive electrode revealed an extraordinary specific capacity of 603 F g-1 at 5 mV s−1 when illuminated. The photoelectrode's brief chronoamperometric response showed the creation of 19.8 mA of photocurrent. In the presence of light, higher photocurrent densities were obtained at each scan rate, demonstrating that exposure to light enhanced the performance of the electrode. A helpful photoelectrode that may be applied to renewable energy systems is unquestionably introduced by this work.
