摘要

介绍了一种用于半连续生产100毫米宽硅带的设备设计。由于晶粒选择是在区域熔化开始时进行的，因此连续加工而不是单片加工是合理的，并导致相当宽的晶粒(约10-20毫米)延伸到整个带的长度。通过刻蚀技术可以揭示晶粒结构和缺陷。由于晶粒内部缺陷密度高，氢钝化效应显著，这一点通过EBIC和LBIC测量得到了证实。由粉末(SSP)材料制成的硅片制成的最好的太阳能电池的效率超过13%。

Silicon ribbons for solar cells grown from powder by the SSP method

The design of a machine for semicontinuous production of 100-mm wide silicon ribbons is presented. As the grain selection takes place at the beginning of zone melting, continuous processing instead of single-sheet processing is reasonable and leads to fairly wide grains (on the order of 10-20 mm) extending over the whole length of the ribbon. Grain structure and defects are revealed by etching techniques. Due to the high intragrain defect density there is a significant effect of hydrogen passivation which is demonstrated by EBIC and LBIC measurements. The best solar cells made from silicon sheets from powder (SSP) material showed efficiencies above 13%.<>
