Popis: | 32nd European Photovoltaic Solar Energy Conference and Exhibition; 1901-1904 This work deals with the phenomenon called Potential-Induced Degradation of PV modules (PID shortly). Currently is this problem solved in a lot of scientific institutes where is analyzed the physical description of the process that occurs due to PID. The cause of PID degradation is in a migration of positive sodium ions from glass (that protects PV modules from the environmental influences) to the PV cell which leads to a negative effect in a pn junction of photovoltaic cell. This article is focused on the entire photovoltaic module. PV module is firstly degraded and then regenerated through an applied voltage of 600 V between the aluminum frame and PV cells of module. The degradation and regeneration process was locally supported by increasing of the temperature of PV module to 80 ° C. In this way was possible to observe the influence of temperature in a PID affected PV module. |
