Designation:E136215Standard Test Methods forCalibration of Non-Concentrator Photovoltaic Non-PrimaryReference Cells1This standard is issued under the fixed designation E1362;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover calibration and characteriza-tion of non-primary terrestrial photovoltaic reference cells to adesired reference spectral irradiance distribution.The recom-mended physical requirements for these reference cells aredescribed in Specification E1040.Reference cells are princi-pally used in the determination of the electrical performance ofa photovoltaic device.1.2 Non-primary reference cells are calibrated indoors usingsimulated sunlight or outdoors in natural sunlight by referenceto a previously calibrated reference cell,which is referred to asthe calibration source device.1.2.1 The non-primary calibration will be with respect to thesame reference spectral irradiance distribution as that of thecalibration source device.1.2.2 The calibration source device may be a primaryreference cell calibrated in accordance with Test MethodE1125,or a non-primary reference cell calibrated in accor-dance with these test methods.1.2.3 For the special case in which the calibration sourcedevice is a primary reference cell,the resulting non-primaryreference cell is also referred to as a secondary reference cell.1.3 Non-primary reference cells calibrated according tothese test methods will have the same radiometric traceabilityas that of the calibration source device.Therefore,if thecalibration source device is traceable to the World RadiometricReference(WRR,see Test Method E816),the resulting sec-ondary reference cell will also be traceable to the WRR.1.4 These test methods apply only to the calibration of aphotovoltaic cell that demonstrates a linear short-circuit currentversus irradiance characteristic over its intended range of use,as defined in Test Method E1143.1.5 These test methods apply only to the calibration of aphotovoltaic cell that has been fabricated using a singlephotovoltaic junction.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E490 Standard Solar Constant and Zero Air Mass SolarSpectral Irradiance TablesE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE772 Terminology of Solar Energy ConversionE816 Test Method for Calibration of Pyrheliometers byComparison to Reference PyrheliometersE927 Specification for Solar Simulation for PhotovoltaicTestingE948 Test Method for Electrical Performance of Photovol-taic Cells Using Reference Cells Under Simulated Sun-lightE973 Test Method for Determination of the Spectral Mis-match Parameter Between a Photovoltaic Device and aPhotovoltaic Reference CellE1021 Test Method for Spectral Responsivity Measurementsof Photovoltaic DevicesE1040 Specification for Physical Characteristics of Noncon-centrator Terrestrial Photovoltaic Reference CellsE1125 Test Method for Calibration of Primary Non-Concentrator Terrestrial Photovoltaic Reference Cells Us-ing a Tabular SpectrumE1143 Test Method for Determining the Linearity of aPhotovoltaic Device Parameter with Respect To a TestParameterG173 Tables for Reference Solar Spectral Irradiances:Direct1This test method is under the jurisdiction of ASTM Committee E44 on Solar,Geothermal and OtherAlternative Energy Sources and is the direct responsibility ofSubcommittee E44.09 on Photovoltaic Electric Power Conversion.Current edition approved Dec.1,2015.Published February 2016.Originallyapproved in 1995.Last previous edition approved in 2010 as E1362-10.DOI:10.1520/E1362-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 Normal and Hemispherical on 37 Tilted Surface3.Terminology3.1 DefinitionsDefinitions of terms used in these testmethods may be found in Terminology E772.3.2 Definitions of Terms Specific to This Standard:3.2.1 calibration source device,photovoltaic,nthe refer-ence cell used to measure the incident irradiance during thecalibration.3.2.2 monitor solar cell,na solar cell used to measure theirradiance of the solar s
