Application areas: Photovoltaic solar energy research and development and production Device Characterization: This is a radiometer used in evaluating the performance of photovoltaic devices using a reference measurement of illumination levels for PV cells. By quantifying the amount of light reaching the test device, it enables the light-to-photovoltaic conversion performance of solar cells and modules to be measured and compared. Reference cells are most commonly used to set the intensity of the light source to a specific test condition (such as one sun) for IV measurements. Reference cells are most commonly used to set the intensity of the light source to a specific test condition (such as one sun) for IV 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.
Reference Cells In the process of solar cell analysis and testing, a standard solar cell is usually used to calibrate the absolute light intensity of the light source, so as to calculate the photoelectric conversion efficiency of the solar cell under test and then conduct analysis and comparison. Especially when testing the IV characteristics of solar cells, a standard solar cell is usually used to calibrate the light intensity of the solar simulator. A standard solar cell is usually composed of a package shell, a solar cell, a temperature sensor, a protective window, etc. Among them, the type of solar cell, the type of temperature sensor, and the material of the protective window can all be selected by the user, and calibration data for the standard solar cell can also be provided. General Features Can be used outdoors (not suitable for long-term outdoor use) or with a solar simulator 2cm×2cm silicon standard solar cell Good thermal contact between solar cell and package housing Temperature detection Four-wire output BK7 glass window Broad spectrum anti-reflection coating on the back of the window and the surface of the solar cell The mounting holes meet the WPVS standard solar cell design requirements Optional GaAs standard solar cell, capable of testing GaAs and CdTe materials Provide your own solar cell for calibration Quartz window instead of BK7 glass window, or filter instead of BK7 glass window to test the specific spectral response of special material solar cells, such as amorphous silicon solar cells RTD temperature sensor or thermocouple Wire connector Customize other sizes of standard solar cells, or customize other sizes of mounting holes Reference Cells This photovoltaic reference cell is a radiometer used for measuring illumination levels when assessing the performance of photovoltaic devices. By quantifying the amount of light reaching a test device, it enables the light-to-electricity conversion performance of solar cells and modules to be measured and compared. Reference cells are most commonly used to set the intensity of a light source to a particular test condition (eg one-sun) for IV 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. We provide reference cells with calibration data.
