Research Abstract

We have found through the analyzes of 2-phenylindazole synthesis from azobenzenes occurring on a vacuum-evaporated TiO_2 film electrode in methonolic solution that the use of semiconductor films composed of small particles is a crucial factor for oxidation-reduction coupled reaction to take place on n-type semiconductors.
We have also found that some Lewis bases, especially alkoxide ion, in solution effectively contribute to the stabilization of CdS electrode against its photocorrosion.
A novel method, combining chemical and electrochemical processes and involving a principle of supersaturation of the solution, has been developed for the deposition of CdS films. Films thus obtained have been found to be composed of small particles and exhibit high light-to-electrical energy conversion efficiency.
