不同模拟环境下高效HJT光伏组件的可靠性研究
RESEARCH ON RELIABILITY OF EFFICIENT HJT PV MODULES UNDER DIFFERENT SIMULATION ENVIRONMENTS
摘要
Abstract
With the advancement of PV power generation technology and innovation in solar cell structures,the photoelectric conversion efficiency of solar cells has been significantly improved,and the output power of PV modules has also increased accordingly.At present,n-type PV modules have gradually become the mainstream in the market due to their high photoelectric conversion efficiency.This paper systematically studies the reliability of HJT PV modules encapsulated with EVA film and high transparency glass under the environment of bias voltage,humid heat,wind/snow load,ultraviolet irradiation,and dry heat.The HJT PV module samples are placed in different simulated environmental chambers and subjected to a series of reliability tests including PID testing,DH testing,mechanical load testing,UV testing,and TC testing.The output power attenuation on the front side and back side of the HJT PV module and its appearance are analyzed.The research results show that after conducting PID testing,DH testing,mechanical load testing,UV testing,and TC testing separately,the output power loss of the front side and back side of HJT PV modules is relatively small,with the highest loss rate of only 1.21%.This means that HJT PV modules have shown excellent reliability in different environments.The research results can provide guidance for the structural design and new material development of high-performance n-type HJT PV modules in the future.关键词
