摘　　要：利用HF和AgNO3混合液刻蚀制备出n型硅纳米颗粒,并将其应用到纳米薄膜太阳能电池。结果表明,随着酸刻蚀时间的延长,硅纳米颗粒的尺寸不断减小,当刻蚀时间为35min时,其尺寸平均值为80nm。将n型硅纳米颗粒作为太阳能电池的窗口材料制备出纳米薄膜太阳能电池器件,发现n型硅纳米颗粒尺寸对太阳能电池的光电转换性能也有明显的影响,随着n型硅纳米颗粒尺寸的减小,太阳能电池的光电转化效率不断提高。The n-type nanograin silicon was eroded with a mixture of HF and AgNOa. The measurement of SEM indicates that the size of nanograin silicon decreases with increase of the ero- ded time. When the sample was eroded for 35 minutes, the smallest value of 80 nm was obtained. As an n-type window material for solar cell, the size of nanograin silicon also has effects on the efficiency of energy conversion from light to electricity. Measurements of I -V curves under illumi- nation with a 1 kW/m2 power at AM1.5 show that energy conversion efficiency increases with decrease of nanograin silicon size.
