About This Item
IEC TS 63109:2022 is a technical document focused on photovoltaic (PV) modules and cells and the measurement of diode ideality factor by quantitative analysis of electroluminescence images. It is relevant when engineering teams, laboratories, or quality functions need a structured way to evaluate PV device behavior from image-based data. By linking electroluminescence analysis with electrical characterization, IEC TS 63109:2022 supports more consistent technical review, documented evaluation, and comparison across testing workflows.
Purpose of IEC TS 63109:2022
The purpose of IEC TS 63109:2022 is to provide a technical basis for determining diode ideality factor through quantitative analysis of electroluminescence images for PV modules and cells. That makes it useful in technical assessment and verification activities where image-derived measurements need to be interpreted in a repeatable way. For engineering documentation and conformity assessment preparation, it helps define a common reference point for analysis methods and supports more reliable comparison between devices, batches, or test results.
Compliance applications of IEC TS 63109:2022
IEC TS 63109:2022 is typically used in laboratory evaluation, product evaluation, and engineering validation for photovoltaic components. It may support inspection of modules and cells during development, incoming quality checks, failure analysis, or manufacturing control where electroluminescence imaging is part of the workflow. Organizations involved in procurement, compliance workflows, or technical validation can use it as a reference when reviewing how diode ideality factor measurements are generated, documented, and interpreted within a broader PV testing program.
Benefits of IEC TS 63109:2022
Using IEC TS 63109:2022 can improve testing consistency and reduce ambiguity in quantitative electroluminescence analysis for PV modules and cells. It supports quality assurance by giving teams a clearer technical reference for measurement interpretation, which may help with risk reduction, operational consistency, and defensible reporting. For procurement and compliance teams, it can also strengthen technical review and conformity assessment preparation by providing a focused document for evaluating whether a laboratory or supplier uses a suitable method.
