Photovoltaic devices - Part 8-1: Measurement of spectral responsivity of multi-junction photovoltaic (PV) devices
IEC 60904-8-1:2017 gives guidance for the measurement of the spectral responsivity of multi-junction photovoltaic devices. It is principally intended for non-concentrating devices, but parts may be applicable also to concentrating multi-junction PV devices. The SR is required for analysis of measured current-voltage characteristics of multi-junction PV devices as described in IEC 60904-1-1.

Dispositifs photovoltaïques - Partie 8-1: Mesurage de la sensibilité spectrale des dispositifs photovoltaïques (PV) multijonctions
L'IEC 60904-8-1:2017 fournit des préconisations relatives au mesurage de la sensibilité spectrale des dispositifs photovoltaïques multijonctions. Elle concerne essentiellement les dispositifs qui ne sont pas à concentration, mais des parties peuvent également être appliquées aux dispositifs photovoltaïques multijonctions à concentration. La sensibilité spectrale est exigée pour analyser les caractéristiques courant-tension mesurées des appareils photovoltaïques multijonctions décrits dans l'IEC 60904-1-1.
Fotonapetostne naprave - 8-1. del: Merjenje spektralne odzivnosti fotonapetostnih naprav z več spoji
Ta del standarda IEC 60904 podaja smernice za merjenje spektralne odzivnosti fotonapetostnih naprav z več spoji. Namenjen je predvsem koncentriranim napravam, vendar se lahko deli uporabljajo tudi za koncentrirane fotonapetostne naprave z več spoji. Spektralna odzivnost je potrebna za analizo merjenih karakteristik tok-napetost fotonapetostnih naprav z več spoji, kot je opisano v standardu IEC 60904-1-1.
Zahteve za merjenje spektralne odzivnosti fotonapetostnih naprav z enim spojem so zajete v standardu IEC 60904-8, ta dokument pa opisuje dodatne zahteve za merjenje spektralne odzivnosti fotonapetostnih naprav z več spoji. V tem dokumentu je obravnavano le merjenje spektralne odzivnosti posameznih spojnih plasti znotraj naprave z več spoji z dvema priključkoma.
Ta dokument se lahko uporablja za fotonapetostne naprave, ki so namenjene za uporabo pri koncentriranem sevanju, če so merjene brez optike za koncentracijo.

PHOTOVOLTAIC DEVICES –
Part 8-1: Measurement of spectral responsivity
of multi-junction photovoltaic (PV) devices
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 60904-8-1 has been prepared by IEC technical committee 82:
Solar photovoltaic energy systems.
The text of this International Standard is based on the following documents:
FDIS Report on voting

PHOTOVOLTAIC DEVICES –
Part 8-1: Measurement of spectral responsivity
of multi-junction photovoltaic (PV) devices
1 Scope
This part of IEC 60904 gives guidance for the measurement of the spectral responsivity (SR)
of multi-junction photovoltaic devices. It is principally intended for non-concentrating devices,
but parts may be applicable also to concentrating multi-junction PV devices. The SR is
required for analysis of measured current-voltage characteristics of multi-junction PV devices
as described in IEC 60904-1-1.
The requirements for measurement of SR of single-junction PV devices are covered by
IEC 60904-8, whereas this document describes the additional requirements for the
measurement of SR of multi-junction PV devices. This document
