摘要
Cu (In,Ga)Se2 (CIGS)太阳能电池的长期性能受到其承受周围天气变化的能力的强烈影响,包括温度、湿度和光照等。在实验中,我们重点研究了未掺杂ZnO (IZO)和Al:ZnO (AZO)的窗层材料在湿热和干热处理下的稳定性。我们发现Al掺杂物增强了ZnO对水分的捕获,从而导致薄膜光学、形态和电学性能的下降。
Investigation of aluminum induced degradation in sputtered Al:ZnO for CIGS solar cells applications
The long term performance of Cu (In,Ga)Se2 (CIGS) solar cells were strongly affected by their ability in withstanding surrounding weather change, including temperature, humidity, and light, etc. In our experiment, we focused on the stability study of window layer materials of undoped ZnO (IZO) and Al:ZnO (AZO) using damp heat and dry heat treatment. We found that the Al dopant had enhanced the capture of moisture in ZnO, and thus caused the degradation in film optical, morphological and electrical properties.
