The International Electrotechnical Commission has released new IEC/TS 62789 standard. IEC 62789 ed. 1.0 applies to “Photovoltaic concentrator cell documentation”. The new edition is available for purchase on the IEC’s website.
“IEC TS 62789:2014 provides guidelines for the parameters to be specified for concentrator photovoltaic cells (both multi-junction and single junction) and provides recommendations and references for measurement techniques. No attempt is made to determine pass/fail criteria for cells. The purpose is to define the performance and physical characteristics of concentrator cells. This specification may also be used for describing cell assemblies and receivers.”
