| 抄録: | We investigate the potential-induced degradation (PID) of n-type interdigitated back-contact (IBC) crystalline Si (c-Si) photovoltaic (PV) modules under a negative bias stress and the influence of light illumination on the PID. IBC PV modules show PID characterized by reductions in short-circuit current density (J_<sc>) and open-circuit voltage (V_<oc>) under negative bias stress, while no fill factor (FF) reduction is observed. The degradation may originate from sodium (Na) introduction into c-Si and resulting enhancement of carrier recombination on the surface of the IBC cells. 1-sun light illumination during the negative-bias PID test results in less severe reductions in J_<sc> and V_<oc>. A reduction in an electric field in the surface Si nitride (SiN_x) film due to carrier generation in the SiN_x and resulting increase in its conductivity is one of the possible explanations for the mitigation of the Na-related PID. |
