28、 (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 Repo
29、rts, 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 n
30、on- 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
31、 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 ar
32、e 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 inte
33、rnational 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
34、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 use
35、rs 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 oth
36、er 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.
37、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 paten
38、t rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despi
39、te repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether t
40、hey can be transformed into International Standards. IEC TS 62789, which is a technical specification, has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. IEC TS 62789:2014 IEC 2014 5 The text of this technical specification is based on the following documents: Enquir
41、y draft Report on voting 82/776/DTS 82/821/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has dec
42、ided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International standard, reconfirmed, withdra
43、wn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer.
44、 6 IEC TS 62789:2014 IEC 2014 PHOTOVOLTAIC CONCENTRATOR CELL DOCUMENTATION 1 Scope and object This Technical Specification provides guidelines for the parameters to be specified for concentrator photovoltaic cells (both multijunction and single junction) and provides recommendations and references f
45、or measurement techniques. No attempt is made to determine pass/fail criteria for cells. The purpose of this specification is to define the performance and physical characteristics of concentrator cells. This specification may also be used for describing cell assemblies and receivers, but is not wri
46、tten to specifically address cell packaging. It is not intended to standardize the properties of the concentrator cells, but to standardize how the properties are communicated. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are in
47、dispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60904-3, Photovoltaic devices Part 3: Measurement principles for terrestrial photovoltaic (PV) solar de
48、vices with reference spectral irradiance data IEC 62787, Concentrator photovoltaic (CPV) solar cells and cell-on-carrier (COC) assemblies Reliability qualification 13 Specifications for concentrator cells All concentrator cell datasheets complying with this specification shall provide, as part of th
49、eir product marking and documentation, the information specified in Table 1 below. See subsequent clauses and subclauses of this Technical Specification for further explanation of individual specifications. In addition to the information indicated by the examples, it is required to include a sketch of the cell and the indicated graphs. Some of the specifications are optional; however, if a concentrator cell manufacturer
