| Abstract | ||
| Highly photosensitive CdS thin films with photocurrent to dark current ratio (Iph/Id) of ~105 under 300W.m-2 illumination were reported. The films are prepared by an electroless chemical deposition technique. The pH value of the solution used in the electroless deposition of cadmium sulfide thin films has been found to affect the deposition rate, optical transmission, photoconductivity, photoconductivity to dark conductivity ratio Cph/Cd and photocurrent decay time. | ||
