4.  Copper oxide thin film being considered thin film in solar cells
due to its photovoltaic properties as it have band gap 2.0 eV [1].
 In this study, Copper oxide thin film electrodeposited on copper
substrate.
 Electrodeposition process is a cheap process as compared to
Thermal Anodic, Chemical ionization, Reactive sputtering [2].
