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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 60904-3 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This fourth edition cancels and replaces the third edition published in 2016. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) all spectral data were recalculated due to some minor calculation and rounding errors in
the third edition; the global spectral irradiance returned to exactly the data of the second
edition;
b) the angular distribution of the irradiance was clarified.

PHOTOVOLTAIC DEVICES –
Part 3: Measurement principles for terrestrial photovoltaic (PV)
solar devices with reference spectral irradiance data

1 Scope
This part of IEC 60904 applies to the following photovoltaic devices for terrestrial applications:
– solar cells with or without a protective cover;
– sub-assemblies of solar cells;
– modules; and
– systems.
NOTE The term “test specimen” is used to denote any of these devices.
The principles contained in this document cover testing in both natural and simulated sunlight.
Photovoltaic conversion is spectrally selective due to the nature of the semiconductor
materials used in PV solar cells and modules. To compare the relative performance of
different PV devices and materials a reference standard solar spectral distribution is
necessary. This document includes such a reference solar spectral irradiance distribution.
This document also describes basic measurement principles for determining the electrical
output of PV devices. The principles given in this document are designed to relate the
performance rating of PV devices to a common reference terrestrial solar spectral irradiance
distribution.
The reference terrestrial solar spectral irradiance distribution is given in this document in
order to classify solar simulators according to the spectral performance requirements
contained in IEC 60904-9.

4 Measurement principles
In current practice the photovoltaic performance of a solar cell or module is determined by
exposing it at a known temperature to stable sunlight, natural or simulated, and measuring its
current-voltage (I-V) characteristic curve while measuring the magnitude of both the incident
irradiance and the PV device temperature. Detailed I-V curve measurement procedures are
included in IEC 60904-1. The measured performances can then be corrected to standard test
conditions (STC) or other desired conditions of irradiance and temperature according to
IEC 60891. The corrected power output at the maximum power voltage and STC is commonly
referred to as the rated power.
Incident irradiance can be measured by means of a PV reference device (whose spectral
responsivity shall be known) or, if measuring under natural sunlight, by means of a
thermopile-type irradiance detector (pyranometer). If a PV reference device is used, it shall
satisfy the requirements specified in IEC 60904-2. Temperature determination of the PV
device under test shall be made according to IEC 60904-1 or IEC 60904-5.
Since a solar cell has a wavelength-dependent responsivity, its performance is significantly
affected by the spectral distribution of the incident radiation, which in natural sunlight varies
with factors such as location, weather, time of year, time of day, orientation of the receiving
surface, etc., and with a simulator varies with its type and conditions of use according to
IEC 60904-9. Regardless of whether the irradiance is measured with either a thermopile-type
radiometer (that is not spectrally selective) or with a reference solar device, the spectral
irradiance distribution of the incoming light shall be known in order to use IEC 60904-7 to
calculate the spectral mismatch between the measured performance and the predicted
performance under the global or direct reference solar spectral distribution defined in this
document. When performing measurements according to the standard test conditions, the
spectral mismatch between the PV device under test and the thermopile is usually much
larger than the spectral mismatch between the PV reference device and the PV device under
test.
When the spectral responsivity of the PV device is known as determined according to
IEC 60904-8, it is also possible to use IEC 60904-7 to compute the performance of that PV
device when exposed to light of any known spectral irradiance distribution.
5 Reference solar spectral and angular irradiance distribution
The reference solar spectral distributions are given in Table 1 and Figure 1.

IEC 60904-3:2019 © IEC 2019 – 7 –
The reference angular distribution is defined for both, the direct and the global spectral
distribution, so that the complete radiation hits the solar device perpendicularly under normal
incidence. Other, more realistic geometrical and ambient conditions for different climate zones
are defined in IEC 61853-4.
The calculation of the spectral distributions was done using the following geometrical and
environmental input parameters:
– global distribution (direct + diffuse + albedo) of sunlight (AM1.5 spectrum), corresponding
–2
to an integrated irradiance of 1 000 W·m incident on a sun-facing plane surface tilted at
37º to the horizontal, and
– the direct distribution of sunlight (AM1.5d spectrum), corresponding to an integrated
–2
irradiance of 900 W·m incident on a sun-facing plane surface perpendicular to the
incident sunlight,
considering the wavelength-dependent albedo of a light bare soil, under the following
atmospheric conditions:
– U.S. standard atmosphere with CO concentration increased to current level (370 ppm), a
rural aerosol model, and no pollution;
– precipitable water: 1,416 4 cm;
– ozone content: 0,343 8 atm-cm (or 343,8 DU);
– turbidity (aerosol optical depth): 0,084 at 500 nm;
– pressure: 101,325 kPa (i.e. sea level).
Data contained in Table 1 have been generated using the solar spectral model SMARTS,
Version 2.9.2. A general description of this model and its suitability to reproduce actual solar
spectral irradiance distributions can be found in “Proposed Reference Irradiance Spectra for
Solar Energy Systems Testing” by C. A. Gueymard, C. Myers and K. Emery , and in the
references therein. Table 1 can be obtained using the data contained in Annex A as an input
to the model SMARTS Version 2.9.2. The resulting output spectral irradiance values have to
be multiplied by a normalization factor (0,997 1) in order to get an integrated irradiance of
–2
1 000 W·m in the wavelength range 0 to infinity for the global irradiance. This same scaling
–2
factor is applied to the direct spectrum giving an integrated irradiance of 900 W·m in the
wavelength range 0 to infinity.
At the time of publication of this document the SMARTS Version 2.9.2 spectral model code is
available, free of charge, subject to the author's license agreement, at
http://www.nrel.gov/rredc/smarts. A copy of the model, not for distribution purposes, is kept
under IEC TC 82 control.
The contents of Table 1 are included in an attached file in the form of an Excel spreadsheet.
