An automated nebulizer spray pyrolysis (ANSP) system is developed for fabricating
p-Zn:CuO/n-Si junction diode. The mechanical carriage for the X-Y movement and the
proposed ANSP system is designed using the SolidWorks design software tool. ATmega-328
microcontroller-based control system was developed to control and move the spray nozzle in
the X and Y-axis direction. Zn:CuO (p-type) precursor solution is sprayed on the silicon wafer
(n-type) using this ANSP system to form p-Zn:CuO/n-Si junction diode. The process
parameters and operating conditions were optimized. The fabricated p-Zn:CuO/n-Si junction
diode parameters such as ideality factor (η) and barrier height (ɸb) were studied under dark and
light conditions using Keithley electrometer. The investigation results revealed that the
junction diode has the lowest ideality factor and barrier height
