Electrochemically deposited ZnO nanostructured array films as antireflection …

In order to improve the short-circuit current and the efficiency of silicon heterojunction solar cells, Ag grid/ITO/(p)a-Si:H/(i) a-Si:H/(n)c-Si/(i)a-Si:H/(nþ)a-Si:H/Al, ZnO nanostructured (NS) array films are deposited by electrochemical method on the front side of the solar cells. Aqueous solutions of ZnCl2 and KCl at temperature of 80 8C were used as electrolyte, employing a three-electrode…
