Photovoltaic devices - Part 1: Measurement of photovoltaic current-voltage characteristics
IEC 60904-1:2020 describes procedures for the measurement of current-voltage characteristics (I-V curves) of photovoltaic (PV) devices in natural or simulated sunlight. These procedures are applicable to a single PV solar cell, a sub-assembly of PV solar cells, or a PV module. This document is applicable to non-concentrating PV devices for use in terrestrial environments, with reference to (usually but not exclusively) the global reference spectral irradiance AM1.5 defined in IEC 60904-3. This third edition cancels and replaces the second edition published in 2006. The main changes with respect to the previous edition are as follows: - Updated scope to include all conditions. - Added terms and definitions. - Reorganised document to avoid unnecessary duplication. - Added data analysis clause. - Added informative annexes (area measurement, PV devices with capacitance, dark I-V curves and effect of spatial non-uniformity of irradiance).
Photovoltaische Einrichtungen - Teil 1: Messen der photovoltaischen Strom-Spannungs-Kennlinien
Dispositifs photovoltaïques - Partie 1: Mesurage des caractéristiques courant-tension des dispositifs photovoltaïques
l’IEC 60904-1:2020 décrit les procédures pour le mesurage des caractéristiques/courant-tension (courbes I-V) des dispositifs photovoltaïques (PV) sous éclairement solaire naturel ou simulé. Ces procédures sont applicables aux cellules solaires individuelles PV, aux sous-ensembles de cellules solaires PV ou aux modules PV. Le présent document s’applique aux dispositifs PV sans concentration destinés à être utilisés dans des environnements terrestres, en référence (habituellement mais pas exclusivement) à l’éclairement énergétique spectral de référence global AM1.5 défini dans l’IEC 60904-3. Cette troisième édition annule et remplace la deuxième édition parue en 2006. Les principales modifications par rapport à l'édition précédente sont les suivantes: - Mise à jour du domaine d’application pour inclure toutes les conditions. - Ajout d’un article "Termes et définitions". - Réorganisation du document pour éviter les doublons inutiles. - Ajout d’un article "Analyse des données". - Ajout d’annexes informatives (mesurage de la surface, dispositifs PV à capacité, courbes I-V dans l’obscurité et effet de la non-uniformité spatiale de l’éclairement énergétique).
