硅基纳米结构太阳电池研究新进展

New progress on silicon-based nano-structured solar cells

由于原材料蕴藏量非常丰富以及对环境无毒友好的特点,硅基太阳电池不仅在当前,而且在今后都将是光伏太阳电池的主流。传统晶体硅电池光电转换原理决定了其转换效率不可能在短期内有较大提高。基于量子限制原理的纳米结构材料具有独特的性能,能够实现全新结构的超高效率的光伏太阳电池。文章介绍了硅基太阳电池研究方面的一些最新研究进展,并指出了未来一些可能的发展方向。

With the advantage of abundance on the earth and nontoxicity,Si-based solar cell will continue to dominate in the future.The efficiency of normal crystal silicon solar cell can not be enhanced in a short time owing to the conversion mechanisms.Nano-structured materials,based on quantum confinement mechanisms,open a window to novel-structure,super-high-efficiency solar cell.This paper introduces some new research progresses in Si-based nano-structured solar and forecast possible aspect in future development.
