| The reliability of III-V concentrator solar cells is an essential task to be carried out before the commercialization of CPV systems based on this kind of solar cells. This paper presents a working plan for assessing the reliability of this kind of III-V concentrator solar cells consisting in accelerated ageing tests and real time tests. The difference between reliability and degradation tests is highlighted as an important issue to be considered. As an example results for a step-stress temperature ageing test are shown, with a Mean Time to Failure (MTTF) of up to 69 years with a bilateral confidence interval of 80%, a reliability value of 70% at 25 years and a failure rate that trends to a steady value after a burning period. | |
