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].

Copper oxide mainly cupric oxide are formed during electrochemical deposition process.

The structural and optical properties of as deposited copper oxide evaluated.

Concentration of CuSO4.5H2O and operating voltage, both increases copper oxide film thickness.

Copper oxide film thickness increases with the increment of time.

Future Aspects To make some strategies to produce on commercial scale. To check the photovoltaic properties by formation of Solar cell from them.
