Summary for copper oxide deposition Discussion
Copper oxide deposition is the goal of a student trying to make thin copper oxide films for a solar cell project, but the electroplating bath he used (CuSO4 and H2SO4 with copper plates at 2 A/dm2) produced only a very faint oxide signal on EDAX. In the thread excerpt provided, only the question is shown, so there is no answerer guidance to compare or summarize. The post asks for suggestions on how to form a copper oxide coating on the anode by electrodeposition, implying uncertainty about whether the bath chemistry, current density, or process conditions are suitable for oxide formation. Because no replies are included, the page mainly documents the problem setup rather than a solution.

Q. I am a Post graduate student of Applied Physics. And I am trying to form thin film of Copper oxide for my solar cell design project (Copper oxide band gap modification by doping using other metal oxides). And from literature I came to know, electroplating is the best way to achieve it, though I had very little experience on it. I used CuSO4 – 150 gpl H2SO4 – 25 gpl bath for the same with 2 Adm-2 (from the literature I had taken this composition) using Copper plates. But on EDAX analysis of the anodes shows a very feeble amount of copper oxide was deposited. Kindly provide a suggestion to form Copper oxide coating in the anode by the electrodeposition process.
Thank you
