Electrodeposition of CulnSe, was investigated in acidic solutions containing Cu~(2+), In~(3+) and HSeO_2~+ ions. The electrodeposition condition was optimized with the aim of obtaining uniform thin films on titanium substrate. The mechanism of the electrodeposition process is discussed. Structure analysis of the deposited film shows a typical polycrystalline chalcopyrite structure, good crystallinity and homogeneous dispersion. The photoelectrochemical cells made of these kinds of deposited films in polysulfide redox solution give distinct photoresponse.
