The station can include a source/meter, reference cell, cell holder, probing assembly, and measurement software, depending upon the configuration required. These products are designed to work with any of Newport's Oriel 2x2 and 4x4-inch standard solar simulators, and the 96000 Research Series Solar Simulator. Not included are a computer system to run the software, a solar simulator, and a workstation. • New! Complete I-V measurement solution for photovoltaic cells • Works with any 2x2 or 4x4-inch Oriel Solar Simulator • Easily integrated with Oriel Solar Simulators in the field • Easy-to-use LabVIEW®™ based I-V characterization software Configuration The Newport I-V Tester has the following intuitive configurator you can easily order either the complete solution or the appropriate subassembly to retrofit to an existing Oriel solar simulator. PVIV- Cell Holder Assy 0: No Holder assy 1: Single chuck for both ref cell and test cell 2: Separate chucks with a moving rail Reference Cell 0: no ref. cell 1: ref. cell included Cell Size 2: 2x2 4: 4x4 The Cell Size indicates the intended solar cell size to be used with the I-V test station. The major difference between the 2x2 option and the 4x4 is the capability of the voltage source/current meter. With the 2x2, you can get up to 3 A, while with the 4x4 you can get up to 5 A compliance current. Also, this implies the correct cell holder size, even though you can still choose not to purchase the holder. The Reference Cell configurator indicates whether the I-V system will include the NREL (National Renewable Energy Laboratory) calibrated Newport Reference Cell, which can be a critical component in obtaining accurate I-V measurements. The Cell Holder Assembly indicates the type of cell holder used. With option 1, the customer receives one chuck for both the Reference Cell and the cell under test. With the 2x2 and 4x4 option selected, the customer will receive a chuck with suitable adapter pieces for the cell size. If the Reference Cell must be available for a calibration at all times, one should consider the Cell Holder Assembly option 2, which consists of two chucks: one for the test cell and the other for the Reference Cell. Both chucks are mounted on a rail assembly. The chucks will have a mechanical register so that each chuck will move to the correct position under the solar simulator each time the chuck is moved. Cell Holder Assembly The basic Cell Holder can interchangeably hold either the Reference Cell or the test cell with a simple adapter piece in place. The Cell Holder is fixed in position with respect to the solar simulator beam, and only the cells on the adapter pieces move. Therefore, the cell position can be maintained with relatively high precision despite the simplicity of the design. 2x2" (left) and 4x4" (right) size cell adapters. The cell is placed on top of the adapter, which sits on the holder. At the bottom is the thermal sensor that measures the temperature of the cell. Reference Cell and Meter The Reference Cell consists of a solar cell assembly and an electronic display where the measured solar simulator irradiance and the cell temperature are displayed. These values are entered in the software to accurately perform the I-V characterization. The Reference Cell can also be used independently of the I-V Test Station, for tuning the solar simulator power level to a desired level of the cell test condition. The Reference Cell is also available as a separate item. For more details, see page 212. Software The LabVIEW based I-V measurement software is easy to understand, and easy to use. A number of critical cell performance parameters are calculated as well as displaying the raw I-V curve. Device ID and User Name can be easily entered from the main user interface, where the configuration set up and the raw data are easily saved into a tab delimited .txt file format report. The software menu also includes a Print Window function, so the measured plot can be printed. Oriel I-V Tester
