准单晶硅技术研究进展

Research Progress on Mono-like Silicon Technology

准单晶硅结合了铸造多晶硅和直拉单晶硅的特点,既具有成本低,产量高的优势,又具有转化效率高的优点。但目前各企业和科研单位对准单晶硅的研究仍处于实验探索阶段。本文系统阐述了准单晶技术的研究进展,介绍了准单晶的两种铸造方法、与传统单晶硅相比所存在的优势、在国内外的发展状况及存在问题,并对其发展前景做了展望。

Mono-like silicon combines the trait of cast multicrystalline silicon and czochralski silicon-low cost, high yield and high conversion efficiency. At present, the companies and institutes study for mono- like is still in experimental stage. The aim of this review article is to provide a comprehensive research progress of mono-like silicon technology, including two casting methods, the advantages compared with the traditional crystalline silicon, and existed problems. Moreover, its prospects are introduced in detail in this paper.
