what are the best binary metals oxide for to generate Solar cell? and the best value of energy gap ?
To build a solar cell you need two semiconductors that build a heterojunction solar cell with the substrate having a bandgap in the order of 1.35 eV acting as absorber and a window layer with wide band gap to allow the passage of the incident solar radiation and completes the junction. If the absorber is p-type the window must be an n type.
Within the the scope of these concepts you can build your solar cells.
Best wishes

Dear Zaid Hamid,
The highest energy conversion is reported from Perovskite Solar Materials. There is plenty of literature on this.
Go through the 2020-special issue, which I reviewed: Let me know, if further information is required.

For a solar cell we need an emitter or window layer which is of high band gap. Some of such material are ZnO, SiC, ITO etc. Band gap of ZnO can be turned by doping with boron, magnesium or aluminum etc. In most of the research papers in the literature one can find band gap of such materials above 3 eV and are suitable for the fabrication of good solar cell. Example: like in case of ZnO the band gap is 3.3 eV.
