项目摘要

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.
通过分析在甲醇溶液中真空蒸发TiO_2膜电极上偶氮苯合成2-苯基林唑的过程,发现利用由小颗粒组成的半导体膜是n型半导体发生氧化-还原耦合反应的关键因素。我们还发现,溶液中的一些路易斯碱,特别是醇氧离子,有效地促进了CdS电极的稳定,防止其光腐蚀。提出了一种结合化学和电化学过程,利用溶液过饱和原理沉积CdS薄膜的新方法。由此获得的薄膜被发现是由小颗粒组成的,并且表现出很高的光能到电能的转换效率。
