Solar Simulators
TriSOL CPV
Concentrating Photovoltaics (CPV) has the promise of producing solar cells with high cell efficiencies, which result in a reduction in the cost of operating a PV module. However, a CPV system requires the integration of CPV solar cells, modules and CPV optics into one efficient system. OAI’s focus is CPV cell testing methodology. The CPV cells can now be tested using OAI’s advanced standalone CPV Simulators for low dose and high dose configurations. The low dose CPV Solar Simulator provides exposure up to 50 Suns, whereas, the high dose CPV Solar Simulator provides exposure up to 1500 Suns. The low and high dose simulators provide exposure in varying Sun concentrations in various beam sizes from 1.5cm x 1.5cm to 7.5cm x 7.5cm, and may be configured with OAI’s I-V Test Systems.

Testing for Si Solar Cells Using High Performance CCD
EL Imaging Tester
EL Testing for Si Solar Cells using High Performance CCD. The determination of luminescence (photo emissions) in solar cells is an important characterization tool. Typical solar cells often have defects which limit the efficiency or lifetime of a cell. Many of these defects are visualized with Luminescence Imaging. By using this technique, the manufacturing process can be optimized to produce better cells. Luminescence Imaging takes advantage of the radiative inter-band recombination of excited charge carriers in solar cells. The emitted photons can be captured with a sensitive CCD camera to obtain an image of the distribution of the radiative recombination in the cell. This distribution is determined by the local excitation level, allowing the detection of electrical losses, thus mapping the diffusion length of minority carriers as the emitted light is low intensity and in the near infra-red range, the CCD camera has a high sensitivity wavelength from 900 to 1100 nm with little thermal noise. This CCD camera provides excellent resolution of 1024 x 1024 pixels with a large 1μm pixel size, multi-megahertz readout speed, and robust USB 2.0 connectivity. The EL CCD Camera is the ultimate high-performance CCD camera for electroluminescence and photoluminescence imaging for Photovoltaic (PV) Cells and Modules. This camera combines low noise electronics and optimal sensitivity in NIR.

IV Curve Tracer
IVCT
In recent years, we have been developing a sophisticated IV curve tracer for PV modules including a maximum power point tracking (MPPT) function. The IV curve tracer is designed for operation with any market-available steady-state solar simulator. Through our web-based software design, the operator can supervise the test results from every computer in a company network. The software contains functions such as an irradiation sum counter that helps to check requirements stated in a stabilization test like they are defined in IEC 61215 (MQT 19). We have also included a correction function to correct the traced IV curves to standard test conditions (STC) when the user enters the required temperature coefficients. One of the most important features is the multi-IV curve tracing function, which enables the user to display more than 150 IV curves in one graph. This eases the analysis of the weakest cells in hot-spot tests, which are required in IEC 61730 (MST 22) and IEC 61215 (MQT 09).

Steady-state Solar Simulator For PV Modules
SORAS LS
In certification laboratories for photovoltaic modules, steady-state solar simulators are mostly used for stabilization / light soaking tests (MQT 19) and hot-spot endurance tests (MQT 09) according to IEC 61215 and IEC 61730. An initial stabilization is required for all PV modules that undergo a standard test procedure. For the hot-spot endurance test (MQT 09), it is important that the operator has easy access to the front and back site of the module. During the test, it is necessary to shade one cell after each other to take infrared pictures, which requires good visibility of the entire back side. Our swiveling module holding system enables easy access to the front and back side of the module.
