Copper oxide and titanium dioxide are promising materials for thin film PV devices.
Copper oxide and titanium dioxide are nontoxic materials.
Titanium dioxide is an n-type semiconductor and in solar cells can acts as a window layer.
Its band-gap of absorbs only ultraviolet light in the solar spectrum.
It ensures efficient electron transport to the front electrode and helps to reduce recombination on the contact.
Cuprous oxide is p-type semiconductor. CuO works as a photon absorber in the cells, allowing for the absorption of most of the solar spectrum and affording a large value absorption coefficient.
See some examples of study copper oxide and titanium dioxide below:

Dear Paulina,
Could you shed some light about the role of the silver nanoparticle in such soalr cells and how can improve the performance of such solar cells.
Many success!

Dear Paulina,
I would like to congratulate you for for this interesting research on metal oxide based solar cells. To your knowledge before the advent of elementary semicondcutor Ge and Si, the rectifiers are made from cupper - cupper oxide diodes.
The introduction of titanium oxide may bring improvement to interface with the cupper oxide absorber material. It is used as an electron transport layer for dye synthesized solar cells and in the perovskite solar cells.
It may be good that you outline in some paragraphs which improvements brought by the TiO2.
My best wishes.
Dear Paulina Sawicka-Chudy ,
Nice discussion, congratulations. Let me just add that you can also play with the morphology of the TiO2. Non-metal materials with high permittivity are smart choices for nanoantenna effects enhancing the optical absorption and the light localization at their surroundings. In particular, TiO2 nanostructures such as nanocolumns, due to their large refractive index, have been shown to localize light even in the visible range. As a result, they can lead to a more efficient light absorption around the nanostructures by a given absorber (for instance perovskite). You can have a look at this work:

Dear Abdelhalim abdelnaby Zekry,
Thank you very much.
Now we are starting a new project "Solar cells based on titanium oxide and copper oxide with Ag nanoparticles". I am very excited and I believe that we will achieve a record of efficiency. Currently, the best efficiency has been achieved for TiO2/CuO - 1.62% [Rohmat 2017].
Dear Jose-Miguel Garcia-Martin .
Thank you very much for this article.
Dear Paulina,
Could you shed some light about the role of the silver nanoparticle in such soalr cells and how can improve the performance of such solar cells.
Many success!
