Investigation of electrical and optical properties of ZnO-CuO composite films by ultrasonic spray pyrolysis method

Key Points

• The study shows that ZnO-CuO composite films exhibit improved electrical properties compared to pure ZnO films, with enhanced conductivity observed.
• Key evidence includes that composite films demonstrated an increase in optical transmittance by 30% compared to single components, indicating better performance.
• Observational analysis using ultrasonic spray pyrolysis method produced ZnO-CuO composite films, evaluating their electrical and optical characteristics for practical applications.
• Highlights the potential of ZnO-CuO films for use in advanced optoelectronic devices, though real-world testing is required to confirm performance.
