Summary: CdS thin films were prepared by chemical bath deposition (CBD), and Sb2S3-y Se (y) thin films were prepared by a hydrothermal method. The quality of CdS thin films as the electron transport layer was evaluated in solar cells with the architecture of FTO/CdS/Sb2S3-y Se (y)/spiro-OMeTAD/Au. A precise preparation strategy, involving adjusting the thickness of CdS thin films prepared by CBD and changing the concentration of the CdCl2 methanol solution in the post-treatment process, was proposed for the first time. The strategy allowed for the successful production of a compact and full-coverage CdS thin film with a thickness of 40 nm and achieved an optimal power conversion efficiency of 8.46%.

Summary: This study investigates the influence mechanism of airflow disturbance on the film uniformity on large rectangular substrates. Both experiments and numerical simulations demonstrate a causal relationship between airflow disturbances and the uniformity of the spin coating film. The results show that film uniformity is affected by solvent evaporation and air shear force caused by airflow disturbance. These findings provide valuable insights into the understanding of the influence of airflow disturbance on film thickness uniformity on large rectangular substrates.

Summary: Organic solar cells are cost-effective and flexible, but small deviations in manufacturing variables can affect their performance. This study systematically examined the effects of precursor solution processing and post-deposition thermal treatment on the optical properties of P3HT:PCBM absorber-layer. The results showed that temperature had the greatest influence on material properties, while stirring time alone was least significant. However, the interaction between stirring time and high temperature promoted structural disorder, leading to degradation of the absorber layer. Design of Experiments indicated that P3HT:PCBM layers with suitable optical properties for OSCs were fabricated with a precursor solution stirred at 53.5 degrees C for 18 hours and post-deposition thermal treatment below 150 degrees C. These findings were supported by X-ray diffraction, microscope optical images, and electrical and optical responses of manufactured solar cells.

Summary: The effects of sandblasting on the surface properties of magnesium sheets were investigated using a central composite design of experiments. The results showed that sandblasting can improve surface roughness, hardness, and corrosion current, and increasing pressure and distance can further enhance these properties. Microstructural analysis revealed that sandblasting leads to grain refinement and the generation of surface defects, which correlate to the modification of surface properties.
