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。The uniformity of the plating layer plays a critical role in the quality of CZTS solar cells fabricated by electrodeposition. A new 3D statistical method based on the traditional 2D comparison was applied. The effects of distance between the electrode plates, side length of the baffle hole, position of the baffle and position of the conductive frame were discussed. The results show that, the optimal distance between the plates is 15 mm, with61.7% flatness; the optimal side length of the hole is 50 mm, with 79.6% flatness; the best position of the baffle is 6mm from the cathode plate, with 79.9% flatness; the optimal position of the frame is 2 mm from the left side of the cathode plate, with 79.5% flatness. The uniformity was examined, with flatness and 3D provided, to be conducive to improve on the deposition process of the fabrication and to upgrade the quality of CZTS.
