The nanostructure's surface reveals the presence of micelles, which are formed due to functionalization with cetyltrimethylammonium bromide surfactant. A thorough examination was conducted to determine the thermal stability of the materials. We discovered that specific samples experienced degradation of the micelle structure after being subjected to a thermal treatment at 400 °C. The degradation resulted in the formation of spherical nanoparticles. The powder X-ray diffraction pattern and Fourier transform infrared spectral measurements indicate that the zinc oxide nanomaterials possess a wurtzite phase. At the same time, their surface exhibits a micelle-like structure due to the adsorption of cetyltrimethylammonium bromide in the SZO1 and SZO2 samples. The FT-IR measurements were conducted for functional group identification and to confirm the formation of surface micelles on the zinc oxide surface. The changes in the zeta potential and polydispersity values indicate the formation of surface micelles well. The surface features and particle size were analyzed using scanning electron microscopy and transmission electron microscopy techniques. The achieved particle size was approximately 10–14 nm, and the initial observation of micelle structures in the SZO1 and SZO2 particles was not sustained after thermal treatment. The absorption spectra of the SZO3 samples reveal the presence of extended absorption edges, which can be attributed to the random arrangement of spherical particles and the notable surface roughness. Incorporating SZO1 and SZO2 in the dye-sensitized solar cell devices significantly improved photocurrent density, resulting in an impressive power conversion efficiency of approximately 4.5 %.
