Later , the discovery of all colures photoluminescence and electric - luminescence from porous silicon and the encouraging progress in fabricating porous silicon based light - emitters has cast a new light on si - based opt - electronics 多孔硅可能弥补单晶硅材料不能有效发光的缺点，预示了用单晶硅制备发光器件进而实现全硅光电子集成的美好前景。
Although the efficiency of the multicrystal si solar celli s lower than that of monocrystal si , the multicrystal si material is cheaper than monocrystal si , so the multicrystal si module has more potential reducing the cost 尽管多晶硅电池效率比单晶硅太阳电池低约2 ，由于其材料制作成本低于单晶硅材料，因此多晶硅组件比单晶硅组件具有更大的降低成本的潜力。
In this paper , firstly , the effect of heavy boron - doping on oxygen precipitation was investigated . after annealed at different conditions , it is found that oxygen precipitation is enhanced by heavily boron doping , especially at high temperature 本文研究了直拉重掺硼单晶硅的氧沉淀行为，着重研究了直拉重掺硼硅单晶中的氧沉淀的热处理、内吸杂、 rtp处理等性能。
Mlg series ultrasoning system is designed by our compeny , combining with the advantages of foreign and domestic trades . the instrument id mainlu used is single monocrystal silicon sheet , electric parts , lens , hardware and precision mechanical parts Mlg系列超声波清洗系统，是本公司结合国外清洗机的特点精心设计，主要运用于单晶硅片、太阳能硅片、电子零件、光学镜片等行业。
Recently , there have been some imaginative attempts to make polycrystalline and ribbon silicon which are lower in cost than high - quality single crystals ; but to date the efficiencies of these apparently lower - cost materials have been unacceptably small 最近，有些人试图研制多晶硅和带状硅，这些材料比高质单晶硅成本小，但是，迄今为止，这些成本明显小的材料的效能低得不实用。
