Foreword
The text of document 82/511/FDIS, future edition 2 of IEC 60904-3, prepared by IEC TC 82, Solar
photovoltaic energy systems, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60904-3 on 2008-05-01.
This European Standard supersedes EN 60904-3:1993.
The main changes with respect to EN 60904-3:1993 are as follows:
− wavelength range extended deeper into the ultraviolet (280 nm instead of 305 nm);
− sunfacing surface considered;
− uniform wavelength intervals used (0,5 nm up to 400 nm, 1 nm up to 1 700 nm, 5 nm up to 4 000 nm);
better resolution than in EN 60904-3:1993;
− more representative atmospheric conditions are considered;
− the model used to generate the spectrum has changed from BRITE to SMARTS (version 2.9), which is
publicly available.
In addition, the terminology annex has been removed from EN 60904-3:2008 because this part is now
included in IEC/TS 61836:2007. The titles of some clauses have been changed (others have been added)
to accord with the usual structure of IEC standards.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2009-02-01

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 60904-3 has been prepared by IEC technical committee 82: Solar
photovoltaic energy systems.
This second edition cancels and replaces the first edition published in 1989. This edition
constitutes a technical revision.
The main changes with respect to the previous edition are as follows:
− wavelength range extended deeper into the ultraviolet (280 nm instead of 305 nm);
− sunfacing surface considered;
− uniform wavelength intervals used (0,5 nm up to 400 nm, 1 nm up to 1 700 nm, 5 nm up to
4 000 nm); better resolution than in the first edition of 60904-3;
− more representative atmospheric conditions are considered;
− the model used to generate the spectrum has changed from BRITE to SMARTS (version
2.9), which is publicly available.

PHOTOVOLTAIC DEVICES –

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



1 Scope and object
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;
– systems.
NOTE The term “test specimen” is used to denote any of these devices.
The principles contained in this standard cover testing in both natural and simulated sunlight.
This standard is not applicable to solar cells designed for operation in concentrated sunlight
or to modules embodying concentrators.
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 standard includes such a reference solar spectral irradiance distribution.
This standard also describes basic measurement principles for determining the electrical
output of PV devices. The principles given in this standard 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 given in this standard is required
in order to classify solar simulators according to the spectral performance requirements
contained in IEC 60904-9.

IEC 60904-9, Photovoltaic devices – Part 9: Solar simulator performance requirements
3 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 rated 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
response must 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.
Since a solar cell has a wavelength-dependent response, its performance is significantly
affected by the spectral distribution of the incident radiation, which in natural sunlight varies
with several 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. If the
irradiance is measured either with a thermopile-type radiometer (that is not spectrally
selective) or with a reference solar cell, the spectral irradiance distribution of the incoming
light must be known in order to make the necessary corrections to obtain the performance of
the PV device under the reference solar spectral distribution defined in this standard as
specified in IEC 60904-7. It is also possible for a user or array designer, using the spectral
response of the cells, to compute within a reasonable tolerance the performance of a PV
device when exposed to light of any other known spectral irradiance distribution. The
methodology for this calculation can be found in IEC 60904-7.
4 Reference solar spectral irradiance distribution
The reference solar spectral distribution AM1.5 is given in Table 1 and Figure 1. This is a total
distribution (direct + diffuse) of sunlight, corresponding to an integrated irradiance of 1 000
–2
W·m incident on a sun-facing plane surface tilted at 37º to the horizontal 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
2
rural aerosol model, and no pollution;
– precipitable water: 1,4164 cm;
– ozone content: 0,3438 atm-cm (or 343,8 DU);
– turbidity (aerosol optical depth): 0,084 at 500 nm;
– pressure: 1013,25 hPa (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
1)
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
