Abstract Flexible thin-film solar cells are important for their advantages in many aspects, and aluminum antimonide (AlSb) can be used as an absorbent layer in thin-film solar cells. However, its deliquescence limits its practical use. In this work, AlSb films were prepared by radio frequency (RF) magnetron sputtering on stainless steel flexible substrates. A flexible conformal coating membrane using acrylic resin was deposited on the AlSb films and its deliquescence prevention effect was verified. It was found that after conformal coating treatment, the deliquescence of the AlSb film was effectively stopped. The bare AlSb films and the Ni/AlSb/acrylic resin/Ni multilayer films were exposed to ambient air at the same time under the same conditions for lengths of time ranging from 1 min to 60 days. After 60 days, the bare AlSb film experienced significant deliquescence, such that the film was completely destroyed. However, the Ni/AlSb/acrylic resin/Ni multilayer films did not exhibit deliquescence.

不锈钢柔性基板上AlSb薄膜的制备及防潮解措施

摘要 柔性薄膜太阳能电池在许多方面具有重要的优势，锑化铝（AlSb）可作为薄膜太阳能电池的吸收层。然而，它的潮解性限制了它的实际应用。在这项工作中，AlSb 薄膜是通过射频 (RF) 磁控溅射在不锈钢柔性基板上制备的。使用丙烯酸树脂的柔性敷形涂层膜沉积在 AlSb 薄膜上，并验证了其防潮解效果。发现经过保形涂层处理后，AlSb薄膜的潮解得到有效阻止。将裸 AlSb 膜和 Ni/AlSb/丙烯酸树脂/Ni 多层膜在相同条件下同时暴露于环境空气中，时间长度为 1 分钟至 60 天。60天后，裸露的 AlSb 薄膜经历了明显的潮解，从而使薄膜完全被破坏。然而，Ni/AlSb/丙烯酸树脂/Ni 多层膜没有表现出潮解。
