Cu(In,Ga)Se₂ absorbers were immerged in deionized water for different times, and specific chemical evolutions were monitored thanks to X‐ray photoemission spectroscopy. Cu(In,Ga)Se₂ related dissolution products were studied in water through induced coupled plasma optical emission spectroscopy. From those analyses, specific surface network disorganization was observed, with Cu migration towards the surface, leading to different kinetics of oxidation and dissolution for each element that could be quantified.

X射线光电子能谱监测水浸过程中Cu（In，Ga）Se2表面的演变

将Cu（In，Ga）Se ₂吸收剂浸入去离子水中不同的时间，并通过X射线光电子能谱监测特定的化学变化。通过感应耦合等离子体发射光谱法研究了水中与Cu（In，Ga）Se ₂有关的溶解产物。从这些分析中，观察到特定的表面网络杂乱，其中Cu向表面迁移，导致每种可以定量的元素的氧化和溶解动力学不同。
