Codoped ZnO films by a co-spray deposition technique for photovoltaic applications
Bin Zhou, Xiaofei Han and Meng Tao

 
Abstract
    A co-spray deposition technique has been developed to bypass a fundamental limitation in the conventional spray deposition technique, i.e., the deposition of metal oxides from incompatible precursors in the starting solution. With this technique, ZnO films codoped with F and Al have been successfully synthesized, in which F is incompatible with Al. Two starting solutions were prepared and co-sprayed through two separate spray heads. One solution contained only the F precursor, NH4F. The second solution contained the Zn and Al precursors, Zn(O2CCH3)2 and AlCl3. The deposition was carried out at 500
