FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60904-1 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This second edition cancels and replaces the first edition published in 1987. This edition
constitutes a technical revision.
The main changes with respect to the previous edition are as follows:
– Added object.
– Added normative references.
– Updated original Clause 2 (General Measurement Requirements), removing Figure 1 as it
is obsolete.
– Provided more detail and guidance on how to measure in sunlight or simulated sunlight.
– Expanded original Clause 6 (Test Report) with requirements based on ISO 17025.

PHOTOVOLTAIC DEVICES –
Part 1: Measurement of photovoltaic
current-voltage characteristics
1 Scope and object
This part of IEC 60904 describes procedures for the measurement of current-voltage
characteristics of photovoltaic devices in natural or simulated sunlight. These procedures are
applicable to a single photovoltaic solar cell, a sub-assembly of photovoltaic solar cells, or a
PV module.
NOTE 1 This standard may be applicable to multi-junction test specimens, if each sub-junction generates the
same amount of current as it would under the reference AM1,5 spectrum in IEC 60904-3.
NOTE 2 This standard may be applicable to PV devices designed for use under concentrated irradiation if they
are irradiated using direct normal irradiance and a mismatch correction with respect to a direct normal reference
spectrum is performed.
The purpose of this standard is to lay down basic requirements for the measurement of
current-voltage characteristics of photovoltaic devices, to define procedures for different
measuring techniques in use and to show practices for minimising measurement uncertainty.
2 Normative references
