Zhonglai Optoelectronics two N-type double-sided components pass the double 85 anti-PID test with excellent results
Recently, the two N-type double-sided modules randomly sampled by Zhonglai Optoelectronics successfully passed TÜV SÜD's strict 96-hour double-85 anti-PID test with excellent performance. The test scores of both components are much higher than the industry's power attenuation by 2%. The excellent standard. "N-type double-sided double glass module" under the test conditions of temperature 85 °C, humidity 85%, voltage ± 1500V, 96 hours after the average attenuation of power is only +0.31%; "N-type double-sided transparent components" at a temperature of 85 Under the test conditions of °C, humidity 85% and voltage ±1000V, the average attenuation of power is only 0.15% after 96 hours. The excellent anti-PID performance of PV modules can ensure the high efficiency and high quality of the components, assure the stable operation and high power generation of the PV system, and in particular ensure the stability of the power plant during the 25-year (or longer) life cycle in special climate conditions such as high temperature and humidity. Operation.
PID full name "Potential Induced Degradation", namely "potential induced attenuation". The PV industry has paid great attention to this phenomenon in recent years, because the PID phenomenon will lead to serious power loss of the components, significant reduction in the opening pressure and fill factor, and the EL of components will be blackened or even completely blackened. The generation of PID is closely related to the characteristics of the package materials, the properties of the anti-reflection film of the battery, and the temperature and humidity of the use environment.
The industry standard is to perform 96-hour PID test at a temperature of 60°C, a relative humidity of 85%, and a voltage of ±1000V for a 96-hour PID test. If the power attenuation of a module does not exceed 5%, it is acceptable, and attenuation is within 2%. The test temperature of the double-sided module was 25°C higher than the common standard, and the attenuation was less than 0.15%. The power stability was outstanding, confirming the excellent reliability of the double-sided module in a high-temperature and high-humidity environment.
