自从前几年出现能源危机以来,太阳光作为“无污染”的能源引起了人们的注意,仅在这数年内,关于太阳光发电的研究就得到了飞速发展。但是,使用太阳电池大规模发电还是十年以后的计划,目前正处在探讨Si以及Ⅲ—Ⅴ族,Ⅱ—Ⅵ族化合物太阳电池的性能和经济前景以及今后发展方向的时期。本文针对Ⅲ—Ⅴ族化合物,尤其是GaAs系太阳电池的以前研究过程、现状和今后应该发展的技术等,展望GaAs太阳电池的将来。 Since the energy crisis a few years ago, sunlight has drawn the attention as a “non-polluting” energy source. In these few years, the research on solar power generation has been rapidly developed. However, the use of large-scale solar cell power generation is still ten years after the plan is currently being explored Si and III-V, Ⅱ-Ⅵ compound solar cell performance and economic prospects and the future development of the period. In this paper, we will look forward to the future of GaAs solar cells in view of the previous research process, current situation and future development of III-V compounds, especially GaAs solar cells.
