Abstract

A cadmium sulfide nanotube (CdS NT) was successfully fabricated by a two-step route consisting of the template-free electrochemical deposition of cadmium hydroxide films at 298K and their subsequent sulfurization by S2− ions. Photo-electrochemical solar cells using a combination of CdS NT, polysulfide (Sx2−/xS2−) and carbon electrode exhibited high IPCE (ca. 80%) at 510nm due to efficient light-harvesting performance.
