Low Voltage DC / Battery Powered HV Amplifiers
WMA-01 And WMA-01LF
-
The Falco Systems WMA-01 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-01LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

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.
