【摘要】 本文以正交实验设计方法分析多晶硅薄膜太阳电池的衬底材料——颗粒硅带——制备工艺参数并进行了优化,采用扫描电镜对颗粒硅带电特性进行分析;并通过对线聚焦加热区的温度场测量分析推断颗粒硅带的物理化学形成过程。本文在工艺优化的基础上同时讨论了颗粒硅带制备工艺的产业化可行性。目前,颗粒硅带上的多晶硅薄膜太阳电池转换效率可达到5%～8%范围(1cm~2)。更多还原

【Abstract】 In this paper the optimization of SSP (Silicon Sheet form Powder) technology as poly-crystalline silicon thin film (poly-CSiTF) solar cells substrate materials is proceeded by othordoxy design method. The performance characterization of SSP by SEM, and estimation of physical and chemical forming process of SSP by temperature field of line focused area are analyzed. Based technology optimization of SSP made by electronic grade silicon powder, this paper also discussed the practical possibility of industrialization. Up to now, the conversion efficiency of the prepared solar cells on low purity SSP substrate without other optimizing processes is usually at the range of 5%-8% (with area of 1cm×1cm).更多还原
