Uncalibrated Photovoltaic Reference Cells Uncalibrated photovoltaic reference cells assist with measurement precision without the price of a calibration traceable to NREL. 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. CalibrationPV Measurements can provide reference cells with or without calibration. Uncalibrated reference cells are a great resource for labs that have a budget constraint and have an alternate method to get a measurement of the reference cell's calibration value. This method can give high precision measurements although the accuracy is lower. For more information on calibrations and calibrated reference cells, please see the Calibrated Photovoltaic Reference Cells page.Features of Most Common Configuration♦ 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 Options♦ Quartz window or colorglass filter for customizing spectral response to resemble that of a particular test material such as amorphous silicon (instead of BK7 glass)♦ RTD temperature sensor or alternative thermocouple type ♦ Cable termination using your preferred connector ♦ Different size solar cell or aperture placed over solar cell ♦ Customer-provided solar cell Other options are available; please contact us to discuss your requirements.
