Photovoltaic devices - Part 11: Measurement of light-induced degradation of crystalline silicon solar cells

This European Standard describes procedures for measuring the light-induced degradation (LID) of crystalline silicon photovoltaic (PV) cells in simulated sunlight. The magnitude of LID in a crystalline silicon PV cell is determined by comparing maximum output power at Standard Test Conditions (STC) before, and after, exposure to simulated sunlight at a specified temperature and irradiance. The purpose of this document is to provide standardized PV cell LID information to help PV module manufacturers in minimizing the mismatch between cells within the same module, thereby maximizing power yield. When compared to PV module LID measurements described in the IEC 61215 series, several extra experimental factors have been found to show significant impact on the PV cell LID test, which were not considered by IEC 61215-2. This document provides a conditioning and measurements procedure and parameter settings required for consistent PV cell LID measurements. LID magnitude is one important factor of cell quality. For cells from the same sorting bin, the most important factor is the distribution of output power after LID.

Photovoltaik-Zellen - Teil 1: Messung der lichtinduzierten Degradation von kristallinen Silizium-Photovoltaikzellen

Cellules photovoltaïques - Partie 1: Mesure de la dégradation induite par la lumière des cellules photovoltaïques au silicium cristallin

l'IEC 63202-1:2019 décrit les procédures pour la mesure de la dégradation induite par la lumière (LID, light-induced degradation) des cellules photovoltaïques (PV) au silicium cristallin sous éclairement solaire simulé. L'amplitude de la dégradation induite par la lumière dans une cellule photovoltaïque au silicium cristallin est déterminée en comparant la puissance de sortie maximale aux conditions normales d’essai ((STC, standard test conditions) avant et après l'exposition à un éclairement solaire simulé, à une température et un éclairement spécifiés.
L'objet du présent document est de fournir des informations sur la dégradation induite par la lumière des cellules photovoltaïques normalisées, afin d'aider les fabricants de modules photovoltaïques à réduire le plus possible la désadaptation entre les cellules à l'intérieur du même module, augmentant ainsi au maximum le rendement de puissance.

Fotonapetostne naprave - 11. del: Meritve degradacije kristalnih silicijevih sončnih celic, povzročene s svetlobo

Ta evropski standard opisuje postopke za meritve degradacije kristalnih silicijevih fotonapetostnih celic, povzročene s svetlobo (LID), pod simulirano sončno svetlobo. Obseg degradacije, povzročene s svetlobo, v kristalni silicijevi fotonapetostni celici se določi s primerjavo največje izhodne moči pri standardnih preskusnih pogojih (STC) pred izpostavljenostjo simulirani sončni svetlobi pri določeni temperaturi in sevanju ter po njej. Namen tega dokumenta je podati standardizirane informacije o degradaciji fotonapetostnih celic, povzročeni s svetlobo, ki proizvajalcem fotonapetostnih modulov pomagajo zmanjšati neujemanje celic v istem modulu, s čimer se poveča izkoristek energije. Ugotovljeno je bilo, da v primerjavi z meritvami degradacije fotonapetostnih modulov, povzročene s svetlobo, ki je opisana v skupini standardov IEC 61215, na preskus degradacije fotonapetostnih celic, povzročene s svetlobo, pomembno vpliva več dodatnih preskusnih dejavnikov, ki v standardu IEC 61215-2 niso bili upoštevani. Ta dokument določa postopek pogojevanja in merjenja ter nastavitve parametrov, ki so potrebne za dosledne meritve degradacije fotonapetostnih celic, povzročene s svetlobo. Obseg degradacije, povzročene s svetlobo, je eden od pomembnih dejavnikov kakovosti celice. Najpomembnejši dejavnik celic znotraj iste razvrstitve je porazdelitev izhodne moči po degradaciji, povzročeni s svetlobo.

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.
