Overview

IEC 60904-1:2006 - "Photovoltaic devices - Part 1: Measurement of photovoltaic current‑voltage characteristics" is an international standard from the IEC that defines procedures and basic requirements for measuring I–V (current‑voltage) characteristics of photovoltaic (PV) cells, sub‑assemblies and modules under natural or simulated sunlight. The standard focuses on consistent measurement practice, spectral and temperature correction, and ways to minimise measurement uncertainty in PV performance testing.

Key topics and technical requirements

Scope and purpose: Procedures for I–V measurement applicable to single cells, multi‑junction specimens (where applicable), and PV modules; includes guidance for concentrator devices when correct spectral/irradiance methods are used.

Reference irradiance measurement: Use a PV reference cell/ module calibrated per IEC 60904‑2 or IEC 60904‑6, or a pyranometer. Spectral mismatch must be corrected per IEC 60904‑7 when the reference spectrum differs from the test specimen.

Temperature control and measurement: Device and reference temperatures must be measured with instruments having ±1 °C accuracy and ±0.5 °C repeatability; apply temperature corrections as per IEC 60891.

Electrical measurement accuracy: Voltages and currents shall be measured with instrumentation having ±0.2% precision for open‑circuit voltage (Voc) and short‑circuit current (Isc). Prefer four‑wire connections and keep leads short. Consider connection method effects for cells vs. modules.

Isc and I–V determination: Short‑circuit current should be measured at zero voltage (preferably by electronic compensation) or extrapolated from the I–V curve under defined linearity limits.

Equipment for natural sunlight tests: May require a two‑axis solar tracker (±5°), spectroradiometer for spectral measurement, and ECT (Equivalent Cell Temperature) methods per IEC 60904‑5.

Solar simulator testing: Requirements for matched reference devices and simulator performance are referenced (see IEC 60904‑9 and IEC 60904‑10).

Measurement uncertainty practices: Guidance to reduce uncertainty, periodic verification of temperature/irradiance correction procedures, and comprehensive test reporting (aligned with ISO/IEC 17025).

Practical applications and users

PV test laboratories and R&D facilities performing cell and module I–V characterization

Manufacturers validating product performance and quality control

Certification bodies and conformity assessment labs referencing standard test methods

PV system designers and researchers requiring reliable performance data Practical benefits include reproducible I–V results, reduced measurement uncertainty, and traceability when comparing module performance across sites or over time.
