摘要

摘要电沉积 CZT 薄膜是获得用于薄膜太阳能电池的 CZTS 吸收层的一种具有成本效益和时间效率的工艺。电沉积薄膜由不同相态的原子混合元素组成，包括铜、锌和锡，这些元素在一段时间内会发生显著变化。使用 XRD 对薄膜进行表征，以探测相的演变，并了解获得稳定相所需的时间。对这些薄膜进行软退火（250 和 350°C）可获得稳定的相位，否则在室温下储存需要更长的时间间隔。软退火后再进行硫化，得到的 CZTS 薄膜具有理想的特性，可用作薄膜太阳能电池的吸收材料。

Phase Evolution during Ageing of Co-Electrodeposited Cu–Zn–Sn Thin Films and Effect of Soft Annealing

Electrodeposition of CZT thin films can be a cost-effective and time-efficient process in obtaining CZTS absorber layer to be used in thin film solar cells. The electrodeposited film is composed of atomically mixed elements in different phases involving Cu, Zn and Sn which change significantly over a period of time. The films are characterized using XRD for probing phase evolution and to understand the time required to obtain stable phases. Soft annealing (250 and 350°C) of these films yielded stable phases that would otherwise take longer time intervals when stored at room temperature. Soft annealing followed by sulphurization yielded CZTS thin film with desired properties to be used as absorber material in thin film solar cells.
