ITS-6200
-
The ITS-6200 is a versatile 10 MHz laboratory frequency reference useful for synchronizing test instruments to a common standard. Eight outputs are provided, each which can be configured independently as sinewave or logic level square-wave signals. Additionally, CMOS logic levels can be set for 5V, 3.3V, or 2.5V logic family compatibility. A 10 MHz reference input is provided to phase lock the ITS-6200 to an external reference, such as a GPS or Rubidium standard, or cascade multiple ITS-6200 units for additional outputs. The low phase noise and high stability OCXO within the ITS-6200 is suitable for the most demanding applications, whether free-running or phase locked. The compact size and low power consumption makes the instrument highly portable and suitable for AC-powered operation in the lab or battery operation in mobile or field applications.

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.
