Can we dope Aluminium into CBD grown ZnO thin films to get Al:ZnO as a window layer in thin film solar cells? If so kindly explain?
I think it possible by using sodium zincate and anhydrous Aluminum chloride.
Thank you sir for your suggetion, could you please let me know is there any data on this?
You could prepared transparent thin films of Al:ZnO with magnetron sputtering. I have done it with good results.
you have to check and calculate the mismatch of Al and ZnO, it is matching and would give good results and this is techanique can be conducted to get a good anti-reflection preformance of the thin film solar cell

I tried to prepared ZnO:B films by CBD, but the results were not good. the film were insulator with poor optical properties and adhesive. But then I grew the film by DC reactive sputtering, I obtain very good results. But I think CBD is nice for preparing buffer layer in CIGS and CZTS solar cells
I agree that sputtering is the easiest way to prepare ZnO:Al with good conductivity. CVD also works well (boron doping). If you insist on a wet-chemical route: Al doping doesn't seem to work in chemical deposition. However, Daniel Lincot and his group have shown that Cl doping works for electrodeposition.
