30、 device 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 standardizatio
31、n 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 ent
32、rusted 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 Inte
33、rnational 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
34、 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 o
35、f 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
36、 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 ass
37、essment 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, emp
38、loyees, 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 t
39、he 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
40、 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 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems.
41、This third edition cancels and replaces the second edition published in 1998 and constitutes a technical revision. The main technical changes with respect to the previous edition are listed below: Re-writing of the clause on testing Addition of a new clause for the measurement of series-connected mo
42、dules Addition of the requirements of ISO/IEC 17025 Additional figures IEC 60904-8:2014 IEC 2014 5 The text of this standard is based on the following documents: FDIS Report on voting 82/822/FDIS 82/843/RVD Full information on the voting for the approval of this standard can be found in the report o
43、n voting indicated in the above table. A list of all parts in the IEC 60904 series, published under the general title Photovoltaic devices, can be found on the IEC website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the content
44、s of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 IEC 60904-8:201
45、4 IEC 2014 PHOTOVOLTAIC DEVICES Part 8: Measurement of spectral responsivity of a photovoltaic (PV) device 1 Scope This International Standard specifies the requirements for the measurement of the spectral responsivity of both linear and non-linear photovoltaic devices. It is only applicable to sing
46、le- junction devices. The spectral responsivity of a photovoltaic device is used in cell development and cell analysis, as it provides a measure of recombination and other processes occurring inside the semiconductor or cell material system. The spectral responsivity of a photovoltaic device is used
47、 for the correction of the spectral mismatch if a PV device is calibrated in a setup where the measurement spectrum is different from the reference spectral irradiance data given in IEC 60904-3 and a reference device with a different spectral responsivity to the device under test is used. This proce
48、dure is given in IEC 60904-7. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced
49、 document (including any amendments) applies. IEC 60904-3, Photovoltaic devices Part 3: Measurement principles for terrestrial photovoltaic (PV) solar devices with reference spectral irradiance data IEC 60904-7, Photovoltaic devices Part 7: Computation of the spectral mismatch correction for measurements of photovoltaic devices IEC 60904-9, Photovoltaic devices Part 9: Solar simulator performance requirements I
