“…bouquet-like morphology developed on the nanotubes. Similar morphology has been reported to strongly influence PEC performance because these types of morphology provide a larger surface area [33]. Further, when the annealing temperature increased to 400 °C, samples with tree-branch-like morphology were observed, as shown in Figure 2g,h.…”

“…Figure 2a,b presents the FE-SEM images of the non-annealed CdSe 0.6 Te 0.4 samples at different magnifications. At higher magnifications, cauliflower-like nanostructures are clearly observed to fully cover the surface of the samples [32][33][34]. The FE-SEM images of the CdSe 0.6 Te 0.4 samples annealed in air exhibit various surface morphologies, as shown in Figure 2c-h.…”

“…Currently, researchers have been using various chemical and physical deposition methods, such as molecular beam epitaxy (MBE) [23,24], chemical vapor [25], hydrothermal [26], radiofrequency sputtering [27], slurry coating [28], non-injection one-pot [29], silicon isolation layer [30], electrodeposition [31], and chemical bath deposition (CBD) [32], to develop ternary CdSe 0.6 Te 0.4 thin films for various applications. Among these methods, the electrodeposition method is simple, rapid, and scalable for preparing ternary CdSe 0.6 Te 0.4 samples [31][32][33][34][35][36][37]. Our previous study investigated the deposition of ternary CdSe 0.6 Te 0.4 composites under different conditions, such as varying bath concentrations, deposition times, and electron-beam irradiation doses [31][32][33][34][35][36][37].…”

We are reporting on the impact of air annealing temperatures on the physicochemical properties of electrochemically synthesized cadmium selenium telluride (CdSe0.6Te0.4) samples for their application in a photoelectrochemical (PEC) solar cell. The CdSe0.6Te0.4 samples were characterized with several sophisticated techniques to understand their characteristic properties. The XRD results presented the pure phase formation of the ternary CdSe0.6Te0.4 nanocompound with a hexagonal crystal structure, indicating that the annealing temperature influences the XRD peak intensity. The XPS study confirmed the existence of Cd, Se, and Te elements, indicating the formation of ternary CdSe0.6Te0.4 compounds. The FE-SEM results showed that the morphological engineering of the CdSe0.6Te0.4 samples can be achieved simply by changing the annealing temperatures from 300 to 400 °C with intervals of 50 °C. The efficiencies (ƞ) of the CdSe0.6Te0.4 photoelectrodes were found to be 2.0% for the non-annealed and 3.1, 3.6, and 2.5% for the annealed at 300, 350, and 400 °C, respectively. Most interestingly, the PEC cell analysis indicated that the annealing temperatures played an important role in boosting the performance of the photoelectrochemical properties of the solar cells.
