Feature：
• Complete I-V measurement solutions for photovoltaic cells
• Works with all Oriel Solar Simulators
• Easily integrated with Oriel Solar Simulators in the field
• Easy-to-use LabVIEW®™ based I-V characterization software

The Oriel® I-V Test Station takes a modular approach to your I-V measurements. The necessary model is based on the current generated by the device under test. Today's
photovoltaic devices incorporate a wide range of efficiency, so your application may require only a small area and generate a higher current or may require a large area of
illumination but generate low current. To address this, Oriel has created basic IV systems that incorporate an appropriate source/meter, cabling, interface, and measurement software into separate models for 1amp, 3 amps, 5 amps, or 10 amps.

The new Oriel PVIV-2.0 software runs I-V measurements and calculates critical parameters such as short circuit current (Isc), current density (Jsc), open circuit voltage (Voc), fill factor (ff), maximum output power (Pmax), cell efficiency, and other standard photovoltaic cell parameters.

In addition, Oriel offers a wide range of Solar Simulators, sampling chucks, probing devices, test stations which allow you to customize a complete I-V solution that meets all your needs. In addition, your choices can be integrated at the factory and delivered as a turn-key system if desired. A typical configuration includes a source/meter, reference cell, cell holder, probing assembly, and measurement software, depending upon the configuration required. These products are all designed to work with any Oriel Solar Simulator.

The current generated by the Cell under test determines which model is appropriiate. With the large range of cell sizes and efficiencies, the choice of Solar Simulator and IV test
components is not directly related to size. The major difference among the models is the capability of the voltage source/current meter (1amp, 3 amps, 5 amps, 10 amps). The user
can mix and match the correct cell holder size, Solar Simulator size and current requirements as well as the accessories needed to put together a complete test station.

Accessories
• Basic sample positioning chuck
• Temperature controlled vacuum chuck
• Electrical probing (Single Point or Bus-Bar)
• Chiller
• Calibrated Reference Cell
• Vacuum Pump
• PV Work Station

Cell Holder Assembly
Various cell holders are available to allow for precise positioning of the device under test. These chuck assemblies are fixed in position with respect to the solar simulator beam. The
cell position can be maintained with relatively high precision despite the simplicity of the design. Vacuum positioning and temperature control are available options on some models.

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 57.

Software
The PVIV 2.0 is a LabVIEW based I-V measurement software suite with an intuitive easy to use interface.

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 IV Software Version 2.0 functions include:
Calculates critical parameters such as short circuit current (Isc), current density (Jsc), open circuit voltage (Voc), fill factor (ff), maximum output power (Pmax), maximum output
voltage (Vmax), maximum output current (Imax) cell efficiency (h) ,Shunt Resistance 1 sun (R@Isc), Series Resistance 1 sun (R@Voc) ,Shunt Resistance Dark IV (RShunt), and other standard photovoltaic cell parameters.

• Viewing of multiple IV measurement results simultaneously
• Multiple data presentation formats for enhanced visualization
• More complete results files stored in tab-delimited ASCII format
• Ability to load previously stored data from disk
• Option to perform "Dark IV" measurements
• Support for new PVIV 10A I-AMP current amplifier hardware

Workstation
The workstation is not included in the I-V Tester part number PVIV-xxx. To complete the system, we recommend the model 91590 Workstation, which includes: a 30x48" Newport VH IsoStation™ Series cleanroom compatible workstation. If other types of workstations are desired, please contact Newport for other options. Note that mechanical clamps are required to mount the components on a breadboard with pre-tapped mounting holes.

Complete Oriel I-V Tester setup on a workstation. Solar simulator and workstation are sold separately. Computer is not included in the Station.
