Calibrated Photovoltaic Reference Cells Use NREL traceable reference cells to ensure accurate light source settings. Reference cells are most commonly used to set the intensity of a light source to a particular test condition (e.g. one-sun) for I-V measurements. Reference cells include a rugged enclosure, solar cell, temperature sensor, and protective window. Cell type, temperature sensor, and window material can be selected to meet your requirements. PV Measurements can provide reference cells with or without calibration. When ordered with calibration, the customer receives calibration certificates citing traceability to NREL as well as I-V and spectral response data. Features of Most Common Configuration♦ Industry lowest profile♦ Low thermal mass ♦ May be used outside (not designed for continuous outdoor use) or with solar simulators ♦ 2 cm by 2 cm square silicon solar cell ♦ Close thermal contact between solar cell and enclosure ♦ Temperature sensor 4-wire contact to the solar cell ♦ BK7 glass window ♦ Broad-spectrum, low-reflectivity coating behind window and surrounding solar cell ♦ Mounting hole pattern (62 mm X 62 mm) compatible with WPVS reference cell design Reference Cell Selection GuideUse the table below to guide you through the selection of reference cell to minimize the spectral mismatch between the reference cell and your device.Your Device, Cell and Window Materials Mono-crystalline Silicon (c-Si) Multi-crystalline Si (mc-Si) Cadmium Indium Gallium di-Selenide (CIGS), Mono-crystalline Si with BK7 or Quartz Amorphous Si (a-Si) Dye sensitized cells (DSC or DSSC), Si with KG1, KG2, KG3, KG5 Amorphous Si/Microcrystalline (a-Si/μc-Si), Si with KG2 and RG610 Gallium Arsenide (GaAs) Cadmium Telluride (CdTe), GaAs with BK7 or Quartz OptionsEnsure a minimal spectral mismatch factor using a photovoltaic reference cell that is optimized for your research.
