IEC 60904-8:2014 specifies the requirements for the measurement of the spectral responsivity of both linear and non-linear photovoltaic devices. The spectral responsivity of a photovoltaic device is used in cell development and cell analysis, as it provides a measure of recombination and other processes occurring inside the semiconductor or cell material system. The main technical changes with respect to the previous edition are listed below: - re-writing of the clause on testing; - addition of a new clause for the measurement of series-connected modules; - addition of the requirements of ISO/IEC 17025.

Overview

IEC 60904-8:2014 is an international standard established by the International Electrotechnical Commission (IEC) that specifies the requirements for the measurement of spectral responsivity of photovoltaic (PV) devices. This standard applies to both linear and non-linear single-junction photovoltaic devices. Spectral responsivity measurement is a critical process used in photovoltaic cell development and analysis, providing insight into internal recombination mechanisms and other semiconductor processes affecting cell performance.

This third edition introduces important updates such as revised testing clauses, new procedures for series-connected module measurements, and incorporation of ISO/IEC 17025 requirements to ensure competent testing and calibration practices.

Key Topics

Scope and Application:

Addresses measurement procedures for spectral responsivity in single-junction PV devices.
Essential for evaluating recombination and semiconductor behavior.
Used in cell development, performance analysis, and correction of spectral mismatch in calibration.

Testing Requirements:

Applies to both linear and non-linear devices.
Specifies conditions for applying white bias light and bias voltage during measurement.
Details testing procedures under continuous and pulsed light sources.

Measurement Setup:

Describes apparatus including monochromatic light sources, device holders with temperature control, PV device electrical contacts, and bias light conditions.
Includes use of reference devices for calibration to ensure accurate spectral responsivity determination.

Series-Connected Modules:

Introduces specific measurement techniques for modules with series-connected cells.
Includes additional apparatus configurations and specialized procedures to isolate individual cells within modules.

Reporting and Marking:

Photovoltaic devices must be marked clearly with manufacturer’s name, device type, base material, and serial number.
Prototype devices must be identified accordingly in test reports.
Test reports detail measurement conditions, device identification, and results in compliance with the standard.

Applications

Photovoltaic Cell Development:

Spectral responsivity measurement helps researchers understand charge carrier recombination and other intrinsic processes influencing efficiency.
Facilitates optimization of semiconductor materials and cell structures.

Quality Control and Calibration:

Ensures standardized performance evaluation for PV cells and modules.
Provides correction factors for spectral mismatch when calibrating PV devices under differing spectral irradiance conditions.
Supports reliable performance verification for manufacturers and testing laboratories.

Series Module Assessment:

Techniques for spectral responsivity measurement at the cell level within modules assist in identifying defective or underperforming cells in complex PV arrays.

Certification and Compliance:

Supports manufacturers and testing bodies in complying with international photovoltaic testing and certification standards such as IEC 61215 and IEC 61646.
