IEC 62108:2016 defines a test sequence that will quickly uncover CPV module failures that have been associated with field exposure to thermal cycling for many years. This document was specifically developed to relate to thermal fatigue failure of the HCPV die-attach, however, it also applies, to some extent, to all thermal fatigue related failure mechanisms for the assemblies submitted to test.

Overview

IEC 62925:2016 is an international standard published by the International Electrotechnical Commission (IEC) that specifies a thermal cycling test for concentrator photovoltaic (CPV) modules. This test is designed to assess and differentiate the increased thermal fatigue durability of CPV modules, particularly focusing on thermal fatigue failure mechanisms such as those affecting the high-concentration photovoltaic (HCPV) die-attach. Serving as a supplement to IEC 62108:2016, which provides general design qualification for CPV modules, IEC 62925 introduces a more rigorous and accelerated test sequence. This ensures a rapid and effective identification of CPV modules' vulnerabilities to thermal cycling stresses during long-term field exposure.

Key Topics

Thermal Cycling Test Procedure IEC 62925 defines a comprehensive test sequence aimed at uncovering failures related to thermal cycling-key in CPV modules subjected to prolonged outdoor operation. The procedure covers sampling criteria, thermal cycling execution, and evaluation methods based on accelerated stress conditions.

Focus on Thermal Fatigue Durability The standard is primarily focused on thermal fatigue failure of the HCPV die-attach but is applicable broadly to other thermal fatigue-related failure mechanisms in CPV assemblies.

Comparison with IEC 62108 While IEC 62108 includes an accelerated thermal cycling test as part of general qualification, IEC 62925 imposes greater stress levels to differentiate modules with superior thermal fatigue durability for more demanding climates and applications.

Sampling and Test Requirements The standard prescribes that test samples must consist of modules with at least 20 separate photovoltaic cells. Failures are determined by a threshold of 5% cell failure rate, encouraging submission of modules with more cells to improve test accuracy.

Test Rate and Duration The required number of thermal cycles and total test duration depend on temperature ramp rates, optimizing accelerated testing without compromising reliability.

Documentation and Reporting IEC 62925 mandates detailed reporting of test procedures, outcomes, and rating criteria to ensure transparent evaluation and facilitate comparability among CPV module designs.

Applications

Quality Assurance in CPV Manufacturing Manufacturers can use IEC 62925 to validate the thermal fatigue resilience of their CPV modules before market release, thereby reducing failure risks in field operations.

Product Differentiation for Harsh Environments The standard enables differentiation between CPV modules based on their ability to withstand intensified thermal cycling stresses common in extreme climatic zones.

Long-Term Performance Prediction By simulating extended operational thermal cycles, stakeholders can better predict module reliability and lifespan, aiding in warranty and maintenance planning.

Research and Development R&D teams benefit from IEC 62925 testing protocols when designing improved die-attach materials and assembly techniques targeting enhanced thermal fatigue durability.
