Temperature-dependent current-voltage, admittance spectroscopy, capacitance-voltage measurements were performed on cesium fluoride (CsF)-treated CIGS solar cell before and after heat-light soaking (HLS) and subsequent heat-soaking (HS) treatments to analyse the defect and metastable properties of the device.It was found that HLS treatment of CsF-treated CIGS solar cell formed cesium-induced defects for minority carrier recombination.The admittance measurement showed a shift of the shallow energy position to a higher value after HLS and subsequent HS, which was due to the formation of a secondary diode toward the CIGS/molybdenum contact.The low-temperature C-V measurement showed that HLS and subsequent HS treatment (HLS/HS) passivate IIICu anti-site defects.

在热浸泡（HLS）之前和之后，对经过温度依赖温度的电流，入学光谱，电容 - 电压测量进行了对经过热浸泡（HLS）和之后的CIGS太阳能电池进行的，以及随后的热浸（HS）处理（HS）处理，以分析设备的缺陷和可遗传性的cigs。 formed cesium-induced defects for minority carrier recombination.The admittance measurement showed a shift of the shallow energy position to a higher value after HLS and subsequent HS, which was due to the formation of a secondary diode toward the CIGS/molybdenum contact.The low-temperature C-V measurement showed that HLS and subsequent HS treatment (HLS/HS) passivate IIICu抗位点缺陷。
