Abstract

Solar cells are a constituent material of photovoltaic modules and are rapidly developing according to various sizes and technological developments. A photovoltaic system generates electricity using such photovoltaic modules as a basic constituent element. In order to ensure stable electricity generation for at least 30 years, the stability and durability of all constituent elements are of course important. In my personal opinion, it is judged that the durability of solar cells should be given priority. In the evaluation of the durability of such photovoltaic modules, domestic and foreign test standards and evaluation standards have already been established, and in Korea, crystalline silicon solar cell modules are evaluated according to KS C 8561. Among the 20 evaluation items, the this paper will discuss the results of evaluation against damp-heat test. The damp-heat test is a very harsh environmental evaluation test in which a chamber test is performed at 85°C and a relative humidity of 85% for 1000 hours. Recently, it is easy to check the evaluation contents of manufacturers and test institutions on the durability performance up to 3000 hours, which far exceeds 1000 hours. Therefore, this research results shared the test contents for the validity of such a long-term damp-heat test and took a scientific approach to obtain long-term reliability.
