Abstract
This paper selects the mainstream single-sided and bifacial p-type PERC mono-Si PV modules on the market as the research object,and conducts in-depth analysis and research on the changes in electrical performance of the two types of PV modules after undergoing different degrees of salt spray corrosion tests and PID tests.The research results show that:1)After the salt spray corrosion test,it is found that salt spray stress had almost no effect on the electrical insulation performance of p-type PERC mono-Si PV modules,and had a relatively small impact on their electrical performance.2)After the salt spray corrosion test,a 96 h PID test is conducted,and it is found that the p-type PERC mono-Si PV modules produced severe PID effects,which greatly affected its electrical performance.Overall,salt spray stress can exacerbate the PID effect of p-type PERC mono-Si PV modules.This is because sodium ions in salt spray in the surrounding environment to penetrate into the solar cells inside the PV modules,resulting in a combined effect of salt spray stress and PID effect.For PV modules that operate at sea for a long time,a single stress cannot perfectly characterize the long-term stress situation faced by p-type PERC mono-Si PV modules in offshore application sites.Therefore,it is necessary to develop comprehensive aging tests to better simulate on-site conditions.关键词
