Annealing Effects of Sputtered Cu2O Nanocolumns on ZnO-Coated Glass Substrate for Solar Cell Applications

الملخص EN

Cuprous oxide (Cu2O) films were prepared on an indium tin oxide glass substrate by radiofrequency magnetron sputtering using a high-purity Cu target.

The temperature of annealing was varied to obtain Cu2O thin films with various elements, compositions, and surface structures.

The p-Cu2O thin films thus formed were characterized by FESEM and XRD.

After annealing at 500∘C, the bilayer structure which consisted of Cu nanoclusters on the surface of a film of Cu2O nanocolumns was observed.

The Cu2O solar cell with the bilayered structure exhibited poor power conversion efficiency.
