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

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

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

1 000 W·m in the wavelength range 0 to infinity for the global irradiance. This same scaling

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.
