随着人类对能源的需要不断增加,太阳能的开发利用日益受到重视。虽然生物的光合作用至今仍是转化和贮存太阳能最有效的方法,但因受自然环境和种植面积等限制,规模难于不断扩大。因此,非生物的光化学方法的研究工作近年来正在不断加强,1976年以来已召开过三届有关太阳能的光化学转化与贮存的国际会议。现在已经找到了若干实验性的光化学方法,可以作为建立实用性技术的基础。不过它们的经济价值如何还有待考察。本文打算简要介绍转化和贮存太阳能的几种光化学方法,都是当前活跃的研究课题。所谓光化学过程,指的是在这个过程中光子的吸收引起一个初级的微观化学变化。如果 With the increasing human needs for energy, the development and utilization of solar energy is increasingly valued. Although photosynthesis of organisms is still the most efficient way to transform and store solar energy, its scale is hard to expand due to the restrictions of natural environment and planting area. Therefore, the research on non-biological photochemical methods has been continuously strengthened in recent years. Since 1976, three international conferences on the photochemical conversion and storage of solar energy have been held. Several experimental photochemical methods have now been found that can serve as a basis for establishing practical techniques. However, how their economic value remains to be seen. This article intends to briefly introduce several photochemical methods for converting and storing solar energy, all of which are currently active research topics. The so-called photochemical process, refers to the absorption of photons in this process caused by a primary micro-chemical changes. in case
