【摘要】：电沉积法制备铜锌锡硫薄膜太阳电池,沉积层均匀性对电池质量起到关键作用。在传统二维比较法的基础上加入了三维统计,建立模型讨论了极板间距、隔板孔边长、隔板位置和导体边框位置对沉积层均匀性的影响。结果表明,极板间距15 mm为最佳,平整度为61.7%;隔板孔边长50 mm为最佳,平整度为79.6%;隔板距离阴极板6 mm处为最佳,平整度为79.9%;导体边框距离阴极板左侧2 mm处为最佳,平整度为79.5%。考察了制备中整个电极板的均匀性,给出了统计的平整度和三维视图,有助于改进电沉积法制备CZTS电池的工艺,提高CZTS前驱体的质量。
[Abstract]:Copper, zinc, tin and sulfur thin film solar cells were prepared by electrodeposition, and the uniformity of deposition layer played a key role in the quality of the cell. Based on the traditional two-dimensional comparison method, the influence of the distance between the polar plates, the length of the hole, the position of the partition plate and the position of the conductor frame on the uniformity of the deposit layer is discussed. The results show that the optimum distance between the plates is 15 mm, the flatness is 61.7, the side length of the diaphragm hole is 50 mm, the flatness is 79.6, the distance between the diaphragm and the cathode plate is 6 mm, the flatness is 79.9; The conductor frame is the best from the left side of the cathode plate at 2 mm, and the smoothness is 79.5%. The uniformity of the whole electrode plate was investigated, and the statistical smoothness and three-dimensional view were given, which was helpful to improve the process of preparing CZTS battery by electrodeposition and improve the quality of CZTS precursor.
